The Quickie Caster Wheel Bearing is designed to keep your caster wheels rolling smoothly, even in harsh environments. Their 7/8 x 5/16 (22mm x 8mm) size is made for all Quickie caster wheels.
We recommend replacing these once a year as part of your yearly wheelchair maintenance. Doing so will allow you to go faster and roll farther with less strain on your body.
Helpful Tip: Two caster bearings are needed for each wheel.
