Fitment Notes:
Generally used as a rear wheel bearing on a variety of manual wheelchairs. It may fit other wheelchair applications. Your existing bearing should have one of these alpha numeric numbers stamped on the shield of the bearing: R8RS7/16, 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 7/16" as R8 or R8RS bearings are also available with 1/2" or 12 mm 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. Click the "Fitment" tab for more information on how to identify or measure your bearing.
