A cylindrical roller bearing is a type of rolling-element bearing that uses cylindrical rollers as the rolling elements placed between the inner and outer races. Unlike ball bearings, which use spherical rolling elements, cylindrical roller bearings use rollers shaped like cylinders. This design enables the bearing to handle higher radial loads because the line contact between the rollers and raceways distributes the load over a larger area.

The rollers are arranged parallel to the bearing's axis, allowing smooth rotation and efficient load transfer. These bearings are typically designed to handle radial loads but can also accommodate limited axial loads depending on their construction.

The main components of a cylindrical roller bearing include:

Inner ring: Fits onto the shaft and rotates with it.

Outer ring: Housed within the bearing seat or housing.

Rollers: Cylindrical-shaped elements placed between the rings.

Cage (retainer): Holds the rollers in place and evenly spaces them to prevent contact and reduce friction.

Raceways: The grooves on the inner and outer rings where rollers roll.

Cylindrical roller bearings come in several designs, such as single-row, double-row, and multi-row types. The choice depends on the load requirements and operating conditions.
