Needle Roller Bearings

Needle roller bearings use small needle rollers (6 mm diameter or less) as rolling elements. These bearings have small cross-sectional areas, high load carrying capacity, high rigidity and low inertia forces, which help reduce machine size and weight. They are designed to withstand vibrations, operate under harsh conditions and be interchangeable with plain bearings. Needle roller bearings are cylindrical roller bearings with a small diameter relative to their length. The improved roller/raceway profile prevents stress peaks, which increases bearing life.

Needle Roller Thrust Bearing Features and Benefits:

Range includes solid, stamped outer ring or cage and roller options High-quality ultra-clean steel can extend bearing life by up to 80% Needle roller thrusting bearings can be divided into radial bearings and thrust bearings depending on the direction of the load they are subjected to. Needle roller bearings have rollers that are three to ten times longer than their diameter and have a relatively large radial load capacity. Applications using needle roller bearings include automotive transmissions or air conditioning compressors.

What is a needle roller bearing used for?

Needle roller bearings are used in automobile components such as rocker arm pivots, pumps, compressors, and transmissions. In many of those applications, needles ride on hardened shafts instead of inner rings.
