in Inch Sizes

Needle Bearings in Inch Sizes are often preferred when high radial loads occur and the available installation space is limited. The needle rollers employed are thin and long, which results in a larger contact area with the shaft. As a result, needle roller bearings in inch sizes can support high loads while maintaining their rigidity.

The compact and lightweight design of needle bearings in inch sizes makes them easy to mount in housing bearings. They are used in diverse areas, including agriculture, construction machinery, pumps and compressors, and the automotive industry, especially in engines and transmissions.

For needle bearings in inch sizes, the diameters of the needles and outer ring are specified in inches instead of metric sizes. They are mainly used in applications developed in countries using the imperial system of measurement, such as the USA.

Needle bearings in inch sizes are not directly comparable to needle bearings in metric dimensions. When selecting the appropriate needle bearing, the defined sizes and specifications should be carefully considered, including their accuracy and tolerance class. These needle bearings usually have higher load capacity and longer service life.
