Roller Bearings

Roller bearings are mechanical components used to reduce friction between two rotating or moving parts. Unlike ball bearings, which use spherical steel balls, roller bearings use cylindrical or tapered rollers to reduce friction.

The inner and outer rings of a roller bearing have raceways that the rollers roll along. As the inner ring rotates, it causes the rollers to rotate as well, reducing the friction between the two surfaces. The shape of the rollers allows them to distribute the load over a larger area, making roller bearings capable of handling heavier loads than ball bearings.

Roller bearings are used in a wide range of applications, from heavy machinery and automotive systems to power transmission and conveyor systems. They are preferred over ball bearings for applications that require higher load-carrying capacity, greater stiffness, and better shock resistance.

There are many different types of roller bearings, including cylindrical roller bearings, spherical roller bearings, needle roller bearings, and tapered roller bearings. Each type has its unique characteristics and is designed for specific applications.
