💡 How do sealed ball bearing swivel casters improve heavy load mobility on workshop floors?
- Most budget setups fail under point loads because thin plates flex and hollow tires vibrate out of control.
- A proper hardened steel body keeps the geometry rock steady when you push past two hundred pounds.
- Sealed double row ball bearings cut friction so dirt never grinds down the raceways over time.
- Polyurethane treads absorb impact shock while staying handy enough to pivot sharp corners on command.
