💡 Why do polyurethane-on-steel core caster wheels improve handling under heavy loads?
The steel core adds strength while the PU layer keeps rolling smooth and quiet.
- Reduced rolling friction helps equipment move easier
- Strong core prevents wheel deformation under weight
- Handy for shop carts, industrial gear, and material handling

This 6 inch caster delivers steady, smooth rolling that makes moving heavy equipment way easier for anyone using it.
