Fitment Notes:
This bearing is used most often on aftermarket manual wheelchair wheels when the wheelchair is equipped with 12 mm axles. Your existing bearing should have one of these alpha numeric numbers stamped on the shield of the bearing: R8RS12mm, R8RS 12mm, R8 or R8RS. It is highly advisable to measure the inside diameter of your existing bearing if the reference number is R8 or R8RS and make sure it is 12 mm as R8 or R8RS are also available with 1/2" or 7/16" inner diameters.

General Wheelchair and Scooter Bearing Notes:
Many bearings found on wheelchairs and scooters have a alpha numeric reference or just a numeric reference number stamped on the side of the bearing which refers to the type and size of the bearing. In most cases, that is all you need to purchase the correct bearing. For alpha numeric reference numbers ending in Z, ZZ, RS, or 2RS, they are all interchangeable (Z and ZZ refer to a metal outer side shield and RS and 2RS refer to a rubber outer side shield protecting the balls inside the bearing). If your bearing has no reference on it, you will have to measure. If the bearing reference appears worn off, you may be able to see it stamped on the other side.
