Here is a set of two 1605-RS sealed mobility scooter & power chair wheel bearings.

These 5/16" x 29/32" (.906) precision caster bearings (1605-RS) are relatively common on skateboards, but are a rare size for mobility products such as electric power chairs. Most often they are found on some Merit's power chair caster wheel assemblies.

Check your existing bearings for the series number, which is usually etched into the side of the bearings.
