Cartridge Wheel Assemblies

These full ball and roller bearing wheel assemblies are suitable for medium to heavy service. The cartridge type bearing housings are designed to be mounted in the truck members with a small amount of side clearance and held in place with a keeper plate. This slight looseness will allow for proper distribution of load.
