What Are Needle Bush Bearings?
05 June 2019

Needle bush bearings consist of a thin, heat treated outer ring formed from accurately controlled sheet steel encasing a set of needles. Bushes may have a full complement of needles retained in the outer ring by their ends or by grease; others have the needles retained in a cage which is prevented from moving laterally in the outer ring.

These needle bush bearings which occupy very little radial space are particularly economical to use and possess a high load capacity, relative to their size. They should be selected in preference to other bearings when conditions of mounting and operation permit.

When needle bushes are used without an inner ring and the needles rotate on a shaft of suitable hardness, they occupy minimum space and therefore provide a very satisfactory solution.

NRB is one such company that manufactures needle bush bearings. The organization offers a wide range of high-precision friction solutions for all mobility applications. The team is a leader in the production of needle bearings and cylindrical roller bearings. The company also manufactures ball bearings, taper roller bearings and all types of thrust bearings.
