Technical Information

WHEEL DEFLECTION CHARACTERISTICS

The amount a No-Crush Wheel will comply or "crush" relies on a few factors including the wheel diameter, width, and polyurethane durometer. Since there are so many variables, we generally recommend starting with a softer durometer first, and then increasing the durometer (harder) when you see the majority of the No-Crush Wheel becoming "crushed" in the application.

For reference, the most popular durometer is 40A.

MOUNTING AND WHEEL ORIENTATION

Applications in which material is being driven/fed by a No-Crush Wheel are mounted opposite from applications in which the No-Crush Wheel is idling.  Use this helpful diagram to determine the orientation of your No-Crush Wheel for best results!

Durometer

The durometer of a Zero Crush wheel can be specified with no effect on the price for any volumes required. For more information on durometer, check out our Technical Information and Frequently Asked Questions (FAQ) section below!

Color

For standard No-Crush Wheels, the color of the wheel is a designation to the durometer of the polyurethane (40A = Yellow, 55A = Blue, etc.), however, ​​NoCrushWheels.com can provide specific durometers to your preferred colors at a slight upcharge, regardless of volume. For colors not shown or for an exact PMS / RGB color match, this can also be done but for an additional cost - Contact Us to find out more.

Mounting / Hub Type

The center hub (or core) of the No-Crush Wheels can be specified for your exact need.  Customers can also provide their own cores (hubs, bushings, bearings, etc.) if this is preferred; otherwise, ​​NoCrushWheels.com can deliver complete to exact specifications.  Generally speaking, unless the bore sizing is something we already have available, it makes the most sense on quantities of 25 or more No-Crush Wheels.

Width

The center hub (or core) of the No-Crush Wheels can be specified for your exact need.  Customers can also provide their own cores (hubs, bushings, bearings, etc.) if this is preferred; otherwise, ​​NoCrushWheels.com can deliver complete to exact specifications.  Generally speaking, unless the bore sizing is something we already have available, it makes the most sense on quantities of 25 or more No-Crush Wheels.

Outside Diameter

All Zero Crush Wheels are molded exactly to size and dimension, using NoCrushWheels.com's time-proven techniques and methods to guarantee maximum quality.  Molding No-Crush Wheels guarantees the exact same size and properties between wheels and batches - time and time again.  To generate a custom outside diameter for a No-Crush Wheel involves producing tooling to this exact dimension and generally starts to make sense for estimated annual usage of 100+ No-Crush Wheels per year.

Spoke Profiles

Customers request custom spoke profiles for their No-Crush Wheels for many different reasons such as matching the exact profile of an existing wheel manufacturer that is no longer in business, wishing to keep the same durometer between all of their No-Crush Wheels but with different compliance properties, and sometimes simply because they have their mind set on something that is unique and specific to their No-Crush Wheels.  Whatever the reason might be, ​​NoCrushWheels.com can deliver custom spoke profiles, generally for orders where the estimated annual usage is 100+ No-Crush Wheels per year.

FDA Compliance

For applications which require FDA-Compliant polyurethane molded No-Crush Wheels, we offer special FDA-Compliant No-Crush Wheels (dry).  This guarantees safe and compliant use of our Zero Crush Wheels for food, beverage, pharmaceutical, and other sensitive applications; this is available for volumes as low as 10 pieces.

Anti-Static

For applications which cannot create a static charge, ​​NoCrushWheels.com offers special additives to its polyurethane anti-static No-Crush Wheels to minimize the amount of static potential and is available for order volumes as low as 10 pieces.

FREQUENTLY ASKED QUESTIONS

This is a very common question related to selecting a No-Crush Wheel, but perhaps the most challenging one to answer accurately!

The durometer of a No-Crush Wheel can be generally correlated directly with how much compliance or "crush" the actual wheel will exhibit.  A harder durometer or larger diameter No-Crush Wheel will exhibit less "give" or compliance than one with a lower durometer or smaller diameter; and while there is no SAE spec or any type of "standard" amount a No-Crush / Zero-Crush Wheel should exhibit, here are some common things to take into consideration when making a selection of No-Crush Wheel for your application:

  1. Force / Load: A heavy item, or one where a large amount of force is desired to hold down, or make contact with the No-Crush Wheel would require a higher durometer No-Crush Wheel.  The lower the durometer, the less force will be required to "crush" the No-Crush Wheel.
  2. Rigidity of Item in Contact: For example in a labeling application, more delicate items such as corrugated cardboard boxes and paper products will be much less rigid than say a wine bottle passing by it.  In both applications pressure is needed to apply a label, but a pre-made cardboard box will be much more susceptible to being crushed versus a wine bottle being broken, by the same durometer and size of No-Crush Wheel.
  3. Other Machine Adjustments: For applications where there is a large amount of variance between the materials coming in contact with a No-Crush Wheel, it is recommended that other areas allow for adjustment, beyond just relying on the "give" or compliance of a No-Crush Wheel.  This can include hinged and spring loaded axles of rotation, machine screws or threaded rods, and other fixturing with adjustment opportunities.

Tech Tip: The most popular durometer of No-Crush Wheels is Shore A 40 durometer, also referred to as '40A'.

Generally speaking, it's best to choose a durometer of No-Crush Wheel to where the load/force exhibited onto the wheel does not completely "crush" the internal spokes of the wheels, as this will thereby max out the compliance of the No-Crush Wheel.  The great part is that ​​NoCrushWheels.com offers five durometers (40A, 55A, 70A, 80A, 90A) to meet all the needs you might have for your exact application.

Is it a device?  A unit of measure? A scale?

Yes!

Durometer - du·​rom·​e·​ter: an instrument for measuring hardness.

Technically speaking, a Durometer is a 'Duro-Meter' which is a device that is utilized to measure the hardness of something.  However speaking more conventionally, Durometer is also used as a unit of measure for the hardness of softer materials.  For No-Crush Wheels and other molded polyurethane rollers, idlers, and wheels, it is effectively how hard or soft the polyurethane which is bonded to the surface really is.Durometer Measurement Tool

There are different scales which polyurethane and other rubber-like materials are measured under, including Shore A, Shore D, and Shore M, ranging from 0 to 100 points; the lower the number, the softer the hardness of the material on a given scale.  Most conventionally molded polyurethanes typically lie in the Shore A and Shore D scales, with all of No-Crush Wheels residing in the Shore A scale.  Below is a helpful chart to give you some real-world examples of what is comparable to the different hardnesses of Shore A and Shore D materials.

Durometer Chart

When selecting a No-Crush Wheel, it is important a Durometer is selected that adequately matches the use in which it is intended for.  Too hard of a Durometer and the No-Crush Wheel will not "crush" or deform enough with regard to the material and force it is coming on contact with.  Too soft of a Durometer and the No-Crush Wheel will "crush" and deform too much.

While there is no set SAE or universal compliance (crush) standard -- ​​NoCrushWheels.com does have useful information to help get you started in the right direction.

The durometer of a No-Crush Wheel can be generally correlated directly with how much compliance or "crush" the actual wheel will exhibit.  A harder durometer or larger diameter No-Crush Wheel will exhibit less "give" or compliance than one with a lower durometer or smaller diameter; and while there is no SAE spec or any type of "standard" amount a No-Crush / Zero-Crush Wheel should exhibit, here are some common things to take into consideration when making a selection of No-Crush Wheel for your application:

While​​ NoCrushWheels.com was created as your single source for high-quality, American-Made, polyurethane No-Crush Wheels in volumes as low as one piece...we equally support high volume original equipment manufacturers (OEM), and maintenance/repair operations too!

The online store at ​​NoCrushWheels.com is set up to be a quick way to find, spec, and purchase No-Crush Wheels! For larger volumes, ​​NoCrushWheels.com accepts blanket purchase order agreements, and can offer discounted pricing and scheduled deliveries to meet your needs for higher volumes.  Get in touch with us to get started!

Generally speaking the most important tolerance aspect of a No-Crush Wheel is the tolerance of the inner core (bore diameter) of the hub, bearing, or surface that mates with whatever is running through the center.

All of the internal cores utilized by ​​NoCrushWheels.com are precision CNC machined and have a tight bore tolerance to ensure maximum concentricity.  Generally speaking all cores have a bore tolerance of +0.002" / -0.000" to accurately slide over and affix to common shaft sizes.

The outside diameter of our Zero Crush Wheels are precision molded to the same diameter each and every time, ensuring you get the same performance on every wheel.  There is no grinding or post-finishing that occurs to the outside diameter, ensuring a smooth and consistent surface is maintained that does not collect debris over time.  Because of the nature and design of no crush wheels however, flex in the actual wheels will happen (by design) and therefore a true total indicated runout measurement is impossible to measure and provide a tolerance for.

The width of our standard Zero Crush Wheels is generally +/- 0.075".  For more detailed datasheets, please click here.

If you have questions or require custom or tighter tolerances, please feel free to contact us!

​​NoCrushWheels.com only manufactures the highest quality of Zero Crush Wheels in the United States of America.  Having end-to-end and full control of all facets of production, from our exclusive industrial ML6 polyurethane base polymers, to strict process control procedures on the production floor guarantees that we produce high quality No-Crush Wheels consistently, each and every time.

Nevertheless, estimating how long a No-Crush Wheel will last in your application is still a challenge due to the wide range of applications and use cases, and subsequent variables that exist.  Generally speaking, the polyurethane durometer, application force / pressure (load), speed, environmental factors, and rotations (cycles) will influence how long a No-Crush Wheel will last in an application.

Generally, the higher the durometer, the less deformation a No-Crush Wheel will have, and it will exhibit less deflection as pressure is being placed on it.  The less cyclic deflection a No-Crush Wheel exhibits, decreases the stress that the grain structure sees and the wheel will be less prone to eventual cracking.  The tradeoff comes with having less "give", and the wheel might not be flexible enough for your application or load being placed on it.

In summary, similar to an automotive tire - "results may vary" based on a multitude of factors and there is no set lifetime a No-Crush Wheel can or should last.  On a whole, we hear many success stories and have a growing list of repeat customers that have ​​NoCrushWheels.com as their single-source supplier of polyurethane No-Crush Wheels for all their applications.

This is a question we even ask ourselves at ​​NoCrushWheels.com sometimes, and to top it off we are certain we haven't even heard them all yet!

Whether at tradeshows, during phone calls, or in-person visits - we hear these types of spoked wheels get called all kinds of different things. About the only thing consistent about their inconsistent naming convention is that the names typically have less to do with their shape, and more about where they are used and what they do.

Some, but likely not all of the names these types of wheels get called include:

  • No-Crush Wheels
  • Zero-Crush Wheels
  • Flex Grip Wheels
  • Durasoft Wheels
  • Pacing Wheels
  • Metering Wheels
  • Bottle Spacing Wheels
  • Hold-Down Wheels
  • Spider Wheels

No-Crush Wheels are incredibly versatile in how they can be used in applications, and below are just a few examples of how they are used and potentially some insight on where this growing list of names may have stemmed from.

No-Crush, Zero-Crush Wheels, and Flex Grip imply that whatever object they are coming in contact with presumably do not get damaged or crushed in the process of passing by the wheels - all the while applying grip or pressure.  For example, corrugated cardboard boxes passing by a wheel which applies pressure to a label applicator needs give to account for variability in box dimensions on a production run.  A No-Crush / Zero-Crush Wheel will have "give" in it, and subsequently avoid crushing or damaging the corrugated cardboard box.

Pacing, Metering, and Bottle Spacing Wheels generally implies something that is held back by the wheel until the appropriate time where the wheel is indexed to then allow for the product to pass along to the next step in the process.  For example, picture a series of wine bottles on a linear conveyor line that get labeled by an applicator machine.  The group of glass bottles will stack up and the Pacing / Metering / Bottle Spacing Wheel indexes to allow individual wine bottles to pass on and get labeled before moving on to the next stage of the process.

Hold-Down Wheels imply that some type of product is being held down onto a base layer, or potentially "joined" to another material but it needs "give" to allow for variance in material thickness.  An example of this would be two layers of adhesive backed papers that package a product in a void in the center.  Obviously pressure needs to be applied to the materials passing by, while allowing for "give" when the actual product being packaged (sandwiched) passes.

As for Spider Wheels -- well, that's anyone guess and the closest thing we have been able to deduce is from the shape of the wheels themselves, but if you have other thoughts, by all means Contact Us -- we would love to hear even more names for these interesting wheels!

A typical lead time for standard No-Crush Wheels for a low volume order (<10 pieces) is typically around two weeks.  Since we have so many variations and sizes, it is difficult to keep them all in stock at all times.  For custom No-Crush Wheels, lead times can vary from 2-6 weeks typically, depending on the complexity of the customized wheels.

Feel free to Contact Us at any time should you have any questions - we are happy to help!

​​NoCrushWheels.com relies on the engineering expertise and manufacturing excellence of its parent company, Meridian Laboratory, Inc. who has been a manufacturer of standard and custom molded polyurethane drive wheels, polyurethane idler wheels, polyurethane coated cam followers, polyurethane coated bearings, robotic gripper fingers, and more since 1963.

Aside from the many things which set Meridian Laboratory and ​​NoCrushWheels.com apart from the competition, bond strength of the polyurethane to the core material itself is one of the things which we are best known for.  Taking the time to properly prep the surfaces, and using tightly controlled processing techniques during the polyurethane molding process guarantees an excellent bond between the polyurethane and the core material.

Oftentimes customers approach us stating how over time and use their rollers and wheels become delaminated from the core, ultimately rendering them useless.  With our proven techniques and expertise you can be guaranteed a No-Crush Wheel that outperforms and outlasts, ultimately providing you less downtime, more savings, and the best return on investment.

No - the default colors assigned to the durometers is a simple way to keep track of the different durometers (hardness) of No-Crush Wheels.
