This 10" x 3" Kingpinless Rubber on Cast Iron Swivel Caster is an economically friendly option that provides decent resistance to shock and vibration, but is not recommended for environments where water or floor debris is present. It is also not recommended for delicate flooring, as it can leave marks when operated in less than ideal circumstances. Featuring a weight capacity of 1,100 lbs., the 80 Shore A black rubber is chemically bonded to a semi-steel wheel core and has an operating temperature range of -40° to +180° degrees Fahrenheit. Rubber on steel wheels provides good floor protection and quiet movement.

Kingpinless caster rigs are different from standard kingpin caster rigs in that the swivel section is held together without a rivet or nut and bolt kingpin. Kingpinless caster rigs are held together by a single row of ball bearings that are contained by a full contact interlocking swivel raceway design. Kingpinless casters are ideal for towing, conveyor, maintenance/utility carts, tow lines, drag lines and more robust applications seen in industrial environments.
