Many bearings cross-over to fit other applications. Please check your existing bearings prior to purchase to ensure that you are ordering the correct type for your machine. Key things to check are the outer diameter, inner diameter, width and bearing code, which written on the outer case of the bearing.

This is used to prevent dirt and grime from entering the rollers and clogging them up. This type of bearing is often found on wheels * NR: The bearing includes a snap ring around its outer diameter, which is used to increase the overall size of the bearing * Z: One side of the bearing rollers is covered by a metal shield to cover and protect the rollers.

The other side will be open. A 6001 RS bearing will have plastic dust covers on either side. A 6001 NR/ZZ bearing wi
