One of the greatest cause of caster failure is a failing kingpin; eliminate the kingpin – eliminate kingpin failure. Colson Enforcer Kingpinless solutions utilize a sealed precision-manufactured single ball hardened raceway to provide strength and resistance for high-impact shock loading and operation over rugged terrain. Handling working loads of up to 2,000 lbs. per caster, Colson 4 Series Kingpinless casters provide the ultimate mobility solution for 2″-wide caster needs. Formed legs are attached to swivel raceway by robotic welding and are finished with attractive, corrosion-resistant zinc plating. A hollow axle with grease fitting, plus grease zerk on swivel raceway, provide continued maintenance ease.
