HomeCYLINDRICAL ROLLER BEARING

CYLINDRICAL ROLLER BEARING

A cylindrical roller bearing is a type of rolling-element bearing that primarily supports high radial loads and, to a lesser extent, axial loads in one direction. It consists of cylindrical rollers held in place by a cage or retainer between two races, typically an inner and an outer ring.

The key components of a cylindrical roller bearing include:

Inner Ring

The inner ring is designed to fit onto a shaft and serves as the raceway for the cylindrical rollers.

Outer Ring

The outer ring provides the housing for the bearing and also serves as a raceway for the rollers.

Rollers

Cylindrical rollers are cylindrical in shape and are arranged parallel to the axis of rotation. They facilitate the movement of the bearing by rolling between the inner and outer rings.

Cage or Retainer

The cage or retainer holds the cylindrical rollers in place and maintains their spacing, ensuring smooth operation of the bearing.

Cylindrical roller bearings come in various configurations, including single-row, double-row, and multi-row designs, to accommodate different load capacities and operational requirements. They are commonly used in applications such as electric motors, machine tools, gearboxes, and automotive transmissions, where high radial loads and relatively low axial loads are present.
