roller bearing

Rotating friction reducer

A roller bearing is a mechanical device that reduces friction between moving parts by using cylindrical rollers instead of balls.

The rollers sit between an inner and outer ring, allowing smooth rotation while supporting heavy loads.

Roller bearings handle greater weight than ball bearings and appear in machinery, vehicles, and industrial equipment: The conveyor system runs on roller bearings.
