PRODUCT OVERVIEW

Understanding the
Cylindrical Roller Bearing

Cylindrical roller bearings are rolling-element bearings designed to carry heavy radial loads at high speeds. Their cylindrical rollers make line contact with the raceways, spreading the load over a larger area and giving higher load capacity and rigidity than ball bearings of the same size.

BEARING CONSTRUCTION: Cylindrical rollers are guided between the inner and outer rings by a cage, with flanges on one or both rings keeping them aligned. This line-contact design carries heavy radial loads with low friction, and many designs allow the rings to be separated for easy mounting and dismounting.

About

Cylindrical Roller Bearings

Every element works together to carry heavy radial loads with controlled, efficient rotation.

IR

Inner Race

The inner ring fits on the rotating shaft and provides the raceway for the rollers.

ROTATING COMPONENT
OR

Outer Race

The outer ring sits in the housing and guides the rollers along its raceway.

SUPPORT COMPONENT
CR

Cylindrical Rollers

Precision rollers make line contact with the races, giving high radial load capacity.

ROLLING ELEMENT
C/R

Cage / Retainer

Keeps the rollers evenly spaced and parallel to the shaft axis during operation.

FAQ

Cylindrical Roller Bearing Guide

Understand the essential information before selecting a bearing for your application.

01 What is a cylindrical roller bearing? +
A rolling-element bearing that uses cylindrical rollers between the inner and outer ring raceways. The rollers make line contact with the raceways, which allows the bearing to carry heavy radial loads at high speeds.
02 Where are cylindrical roller bearings commonly used? +
In applications that need to carry heavy radial loads with rigid shaft support, such as electric motors, gearboxes, pumps, compressors, rolling mills and other heavy machinery.
03 Why do cylindrical roller bearings carry higher loads than ball bearings? +
Their rollers touch the raceways along a line instead of at a single point. This spreads the load over a larger contact area, giving higher load capacity and greater rigidity than a ball bearing of the same size.
04 What are the main parts of a cylindrical roller bearing? +
A cylindrical roller bearing consists of an inner ring, an outer ring, cylindrical rollers and a cage that keeps the rollers evenly spaced. Flanges on the rings guide the rollers and keep them aligned.
05 How do I select a cylindrical roller bearing? +
Bearing selection typically depends on factors such as bearing size, load, speed, shaft and housing dimensions, operating environment, lubrication and the requirements of the specific machine.
06 What information should I provide when requesting a bearing? +
Providing the bearing number, dimensions, application, machine type, operating speed and load requirements can help identify a suitable bearing specification.
