Six inch kingpinless swivel caster with poly urethane wheel
✔️ 6 inch poly tire, cast iron rim, 3/4 inch sealed bearings

Sold individually as a single heavy duty unit, this kingpinless caster handles warehouse ramps and industrial workstations. The rigid steel frame and tough poly urethane tread absorb vibration while moving tool bins across cracked concrete. Shop crews rely on this setup for reliable daily logistics.

✅ Six inch polyurethane surface glides quietly over gravel and shop floors
✅ Kingpinless roller design cuts turn radius for tight aisle navigation
✅ Forged cast iron core carries maximum deck weight without bending
✅ Three quarter inch sealed balls trap moisture away from contact points

💡 Why should maintenance teams choose kingpinless caster models for utility racks?
These handy pivot systems spread thrust load across rollers instead of grinding metal pins. * Dry packed grease seals keep abrasive grit away from the raceway * Split raceway housing takes weight shock without metal flexing * Standard plate pattern fits existing bolt holes for quick wrench installs
