Single kingpinless swivel caster with poly wheel for warehouse tasks
✔️ Single poly urethane 8x3 inch caster on cast iron core with sealed bearings

This kingpinless swivel caster pairs a thick poly urethane tread over a solid cast iron core to eat up impact while shipping goods around busy yards. You will find it mounted on utility carts, hospital beds, and storage racks where smooth rolling and steady load support matter most.

✅ Swivel head rotates fully for tight corner navigation without dragging equipment ✅ Sealed precision ball bearings cut friction and handle heavy point loads easily ✅ Flat mounting plate sports pre drilled holes for quick bolt down application

💡 What sets a kingpinless design apart from traditional pinned casters when pushing heavy equipment?
This kingpinless build skips the center pivot bolt that usually grinds down on older wheels, making it a handy fix for shop managers who hate downtime.
- Hardened steel raceways spread weight evenly across the tread to prevent flat spotting
- Rigid cast iron housing stops lateral wobble during sharp turns and steep ramps
- Low friction seals keep dust out while letting the bearing spin smoothly over grit
