Needle Roller Bearings – What Are They?
11 October 2018

A needle roller bearing is a bearing that uses small cylindrical rollers. These rollers are used to reduce friction of a rotating surface. Compared with ball bearings, needle roller bearings have a large surface area that is in contact with the bearing raceway journals.

The typical structure of a needle roller bearing comprises an inner race (or sometimes just a shaft), a needle cage which orientates and contains the needle rollers, the needle rollers themselves, and an outer raceway. There are many different designs of needle roller bearing, including drawn cup, precision race, caged roller, and thrust roller.

Essentially, needle roller bearings have

• Higher load capacity than a single-row ball or roller bearings of comparable OD.
• The ability to handle a larger, more rigid shaft in a given application.
• Excellent rolling characteristics within a small cross-section.
• Generally lower cost, especially for the drawn-cup type compared with machined versions.

This technical advantage has made the needle roller bearing the preferred choice of bearing in a wide variety of industrial applications over the years.
