💡 Why use polyurethane-covered ball bearings in machinery?
They’re made for durability and shock resistance under load.

• Polyurethane layer resists wear and tear better than rubber

• Handles impacts and heavy stress with added toughness

• Commonly used in wheels, rollers, and mechanical drive systems

This bearing brings extra toughness with smooth rolling action, grab one today and keep your system moving reliably.
