3/8 x 7/8 in. 1604Z Precision Wheelchair or Scooter Bearing Fitment Notes
Fits some Rascal casters. Your existing bearing should have one of these alpha numeric numbers stamped on the shield of the bearing: 1604ZZ, 1604Z, 1604RS or 16042RS. It may fit other wheelchairs or scooters needing the same size or with one of these reference numbers.
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.

3/8 X 7/8 inch ball bearing(s), May 6, 2022 By James Francom (Evanston, WY)(Verified)
I purchased 4 of these (Chinese generic) bearings to replace the bearings inside of the front casters on my 'TiLite AreoR' wheelchair. My cost to replace all 4 bearings was $20 total. And it only took15 minutes of work to knock out the old bearings, and then tap the new ones back into the wheels. That is way better on the ol' wallet than my previous experiance of having to buy 2 replacement caster-wheel-and-bearing assemblies for a total of $170.
Let's hear it for the consumer's "right to repair"!
No more $5000 wheelchairs for me. Not when you can get replacement parts this cheap.
