Caster bearings are one of the most frequently replaced items on a wheelchair. The 11 mm caster wheel bearings for the Drive Medical Cirrus IV, Cruiser X4, and Silver Sport 2 manual wheelchairs are designed for hard use, but any bearing will eventually seize-up if not kept lubricated.

This is the 11 mm bearing that is used on the 8" Front Caster Wheel Assembly with 11mm Bearings for the Drive Cirrus IV, Cruiser X4, & Silver Sport 2 Manual Wheelchair.

Note: Drive Medical states that this bearing is serial number specific. It is compatible with wheelchairs chairs with a serial number beginning with 5D.
