Needle Roller Bearings

Needle roller bearings are used to help prevent stress on rollers. Designed small in diameter, these bearings can help extend bearing service life. Find durable needle bearings that can be used in engine components like rocker arm pivots, pumps, compressors, transmissions and more.Metric shell type needle roller bearings have high length-to-diameter ratios. They are commonly used in farm and construction equipment, gasoline engines, gas pumps, and small appliances. Needle bearings have smaller rollers and the highest load capacity for a given radial space of all rolling bearings.Needle roller bearings are used to help prevent stress on rollers. Designed small in diameter, these bearings can help extend bearing service life.

A built-in thrust ball bearing reduces wear from adjacent shaft components, while the needle rollers support high radial loads. Install anywhere you would use separate bearings for radial and thrust loads.. For technical drawings and 3-D models, click on a part number.
