SR8 is the stainless steel counterpart of the R8 bearing, with the same 1/2 x 1-1/8 x .3125 in dimensions. This four-pack is intended for shower wheelchairs, where ordinary steel bearings corrode. The bearings are ABEC-1, closed with rubber seals and packed with Multemp SRL water-resistant grease. The seller names the RAZ SP shower chair and other shower chairs with a 1/2 in axle.
Suits shower and commode wheelchairs with 1/2 in axles that take an SR8 bearing, including the RAZ SP named by the seller. It is also an option for everyday chairs used near salt water, if the size matches.
