You can measure to check the shaft diameter to make sure it is the right bearing if you're not sure or, look for the number 205 on the bearing. Shaft diameter is 1" = 25.4mm.
Be careful, as there are also bearings that look the same as this on some of the equipment but with a 3/4" and 1 1/4" shaft size.
Some units use a back seal, please select that variant when adding to cart if required.
