I ordered these bearings to replace worn out bearings in my handyman table saw. My engine is the R871 model. They fit perfectly. After putting the engine back together, it purred like new. I can't find any bearing noises, at least they seem to be quieter than before. When I received them the bearings were in a soft plastic case that keeps them all lined up so I don't have to worry about a little extra bearing noise. vicinity.
