Modular top plate/raceway design allows for several top plate and mounting hole configurations. Elimination of kingpin eliminates the number one cause of swivel caster failure. Patented heat-treated raceways reduce bearing indentations caused by impact loads allowing the swivel section to turn easily in the roughest applications. Patented precision-machined raceway: reduces raceway wear, improves swivel action, reduces maintenance and provides longer service life.

RWM is the originator of the Kingpinless ™ caster, the most emulated caster in the industry today. RWM’s Patented Offset Raceway – Why It’s a Superior Design Our patented offset precision-machined raceway exerts radial force evenly where there is full contact between the ball bearing and the raceway. The result: No direct “hammering” forces on the intersections of the raceways Vastly reduced raceway wear Elimination of the “pull apart” forces of stress in the swivel section Smoother swiveling action High maneuverability Longer service life Less maintenance Extra impact resistance High...

More Reasons to Buy RWM Kingpinless ™ Casters No caster shimmy. Superior strength means superior performance – and RWM’s patented swivel section provides the strength to build longer swivel leads that function flawlessly – even at high speeds – without shimmy. We have applied over 100,000 pounds of impact forces to our 125 series with a 5” swivel lead with no damage to the swivel section. Closer machine tolerances. RWM swivel section tolerances are .017, compared with .030 for the competition. This differential represents the amount of play between the top plate and the swivel yoke. The...
