Polyurethane on Polypropylene

Medium duty casters are designed with a kingpin in the swivel with a double row ball bearing for smooth turning. Casters come in swivel, rigid, and brake casters. Polyurethane on Polypropylene wheels are composed of injection molded polyurethane treads which are mechanically bonded to a polyolefin core. The polyurethane tread is molded in, around and through a ribbed extension of the core to prevent debonding. These wheels withstand exposure to many chemicals, solvents, water, and acids. They are especially suited for use in Research Laboratories, Hospitals, Food Service, Schools, Bakeries and other Institutional applications.
