1/2 x 1 3/8 in. with Ring 1621RS Precision Wheelchair or Scooter Bearing Fitment Notes
This bearing features a snap ring around the outer diameter. Your existing bearing should have one of these alpha numeric numbers stamped on the shield of the bearing: 1621RS, 1621-2RS, 1621Z, 1621ZZ. Also verify it has the snap ring as their is the same bearing without the ring.
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.
