SELF-ALIGNING PERFORMANCE

Spherical Roller Bearings

Heavy-duty bearings with two rows of barrel-shaped rollers running on a spherical outer raceway. They carry very high radial loads and axial loads in both directions while tolerating shaft misalignment in mining, cement, paper mills, crushers, gearboxes and heavy machinery.

PRODUCT OVERVIEW

Understanding the
Spherical Roller Bearing

Spherical roller bearings are self-aligning rolling-element bearings designed to carry heavy radial loads along with moderate axial loads in both directions. Their barrel-shaped rollers run on a spherical outer raceway, allowing the bearing to tolerate shaft misalignment and deflection in demanding industrial applications.

BEARING CONSTRUCTION: Two rows of barrel-shaped rollers run between a double-grooved inner ring and a common spherical outer raceway. This design provides self-alignment, high load capacity and dependable performance under shock loads and vibration.

About

Spherical Roller Bearings

Every element works together to carry heavy loads and accommodate shaft misalignment.

IR

Inner Race

The inner ring fits on the rotating shaft and has two raceways, one for each row of rollers.

ROTATING COMPONENT
OR

Outer Race

The outer ring has a single spherical raceway, which lets the inner ring and rollers tilt to absorb misalignment.

SUPPORT COMPONENT
SR

Spherical Rollers

Barrel-shaped rollers in two rows carry heavy radial loads and axial loads from both directions.

ROLLING ELEMENT
C/R

Cage / Retainer

Keeps both rows of rollers evenly spaced and guided during operation.

FAQ

Spherical Roller Bearing Guide

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

01 What is a Spherical Roller bearing? +
A Spherical Roller bearing is a rolling-element bearing that uses balls between 2 rollers and heavy raceways to support rotating components and reduce friction during motion.
02 What are Spherical Roller bearings commonly used for? +
Heavy-duty industrial machinery that experiences high radial loads, shock forces, and shaft misalignment.
03 How do Spherical Roller bearings reduce friction? +
Replacing sliding contact with rolling contact and automatically adjusting to shaft misalignments so the rollers never bind.
04 What are the main parts of a Spherical Roller bearing? +
The main components are generally the inner race, outer race,replacing sliding contact with rolling contact and automatically adjusting to shaft misalignments so the rollers never bind and cage or retainer. Some bearing designs may also include seals or shields.
05 How do I select the Spherical 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.
