Manufacturers of covered bearings and guide wheels for material handling and automated conveyor applications.


Examples of the different types of urethane covered bearings

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

The urethane cover minimizes wear and tear on the bearings — as well as protecting machinery.

Covered bearings are also known as diverter wheels, guide wheels, slide shoes, and AGV stacker wheels.

Made to your specification

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

Precision covered bearings

Guide Wheels / Diverters

Guide wheels and diverter wheels are used for automated conveyor and material handling applications. The red wheel features a single bearing; the green one a double bearing.


Guide Wheels with Machined Radius

Covered bearings with a machined radius allow these guide wheels to serve a multitude of material handling purposes.


Heavy-Duty Support Wheels

Urethane wheels with double bearings support heavy loads on automated conveyor systems (e.g. luggage).

Configuration options

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. Other configurations available on request.

Straight Grind


Chamfer with Shoulder Bushing Pressed In

Single Bearing Centered with Radius

Double Bearing with Radius on Both Ends


Special Requests

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
