Set of 2 6900ZZ shielded wheel bearings found on some models of Jazzy power chairs, from Pride Mobility. Made of carbon steel, these bearings can rotate up to 48,000 rpm. This size bearing is also sometimes referred to as simply a 6900Z bearing.

Bearings are closed with metal shields to protect the bearing from dust or any possible contamination and are self lubricated (bearings are already greased).

Note that 1 set is required for each wheel.
