6900ZZ (6900Z) Shielded Scooter Wheel Bearings (Set of 2)

Set of 2 6900ZZ shielded wheel bearings. 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).

In addition to their primary job of allowing wheels to spin, this bearing is also used by Baja Motorsports as the fork bearings on their Doodle Bug mini bikes.

Note that 1 set is required for each wheel or fork.
