12 Inch Extra Heavy Duty Swivel Caster Set Featuring Blue Polyurethane On Cast Iron Wheels With Bolt On Swivel Locks For Smooth Cruising Action And Shop Workhorse Load Capacity

Extra Heavy Duty 12 Inch Blue Swivel Caster Set With Locks
✔️ 12 inch poly wheels support 3500 lbs each for shop equipment

This caster set rolls your workshop gear across concrete and tile floors. You bolt four sturdy plates directly to welding rigs and platform trucks. The blue poly tread grips well without scuffing your shop surfaces.

✅ Set of four 12 inch swivel casters with bolt on swivel locks
✅ Kingpinless hot forged steel builds for severe shock loading
✅ Non marking polyurethane treads protect concrete and hardwood
✅ Top plates span 5¼ by 7¼ inches for quick bolt down installs

💡 Why pick kingpinless bearing systems for heavy material handling
- Conventional pins fracture when you drop sudden shop loads
- Hardened steel balls absorb vertical thrust and lateral sway
- Heat treated housings maintain tracking through rough job sites
- You save downtime by swapping out worn hardware less often
