Kingpinless Casters

On a swivel caster, the point at which a failure is most likely to occur is at the swivel section or “swivel raceway” of the caster. This area of the caster is exposed to great amounts of torque and stress which can cause the raceway to loosen up. As it loosens, ball bearings from the swivel raceway can fall out affecting the swiveling capabilities of the caster. This loosening can eventually lead to buckling of the caster entirely which immobilizes the piece of equipment your casters are intended to move. For applications which require higher weight capacities, towing capabilities or more abusive environments, my team and I recommend a Kingpinless Caster. A Kingpinless raceway is much stronger than a normal swivel raceway with a kingpin in it. Constructed of a top plate with an inner raceway and an outer raceway, the rigs legs are welded to the base for the wheel to be installed. The outer raceway is fastened to the inner raceway using a series of ball bearings installed through the ball bearing loading hole. This load hole is then sealed once the required amount of bearings is installed which then insures the caster is permanently fixed together. Designed for higher towing speeds, higher levels of abuse and heavier weight loads, the Kingpinless caster design eliminates the leading cause of caster failure and is the perfect fit for many of these higher abuse applications.
