Manufacturers of covered bearings for industrial and manufacturing applications.


Examples of the different types of urethane covered bearings

Urethane covered bearings reduce the noise and vibration associated with bearings moving at high speed on conveyor lines — while allowing the inner diameter (ID) of the bearing to spin freely of the outer diameter (OD).

The urethane cover also minimizes wear and tear on the bearings — as well as protecting machinery. See our Covered Bearings Tech Tip for additional information.

Made to your specification

If requested, UI can include features in the profile of your covered bearing, such as a name or part number, and many types of configurations. Within each configuration, we can do the shoulder bushing, the OD profiles, or double bearings.


In addition to the modifications listed here, we can accommodate your special requests:

  • Creating a color code system based on durometer for easy identification – especially useful if you have the same bearing design serving multiple uses
  • Making the urethane cover to any size or specification
  • Performing secondary machining operations as requested

We can supply bearings to your specification or you can send us your new bearings to cover.


For this modification, the customer wanted a groove machined into the bearing as a secondary operation (machining performed at our in-house machine shop). And, since a belt runs on the covered bearing, tolerances were quite tight.


These urethane covered bearings have a machined radius. Features like this allow covered bearings to serve a multitude of purposes.


A double bearing configuration works well when significant side-loading is an issue. A single bearing takes the brunt of the load and thus is prone to failure; the double bearing just laughs and keeps right on rolling.
