Description

BRS Bearing Heavy-duty Needle Roller Bearings
Heavy-duty needle roller bearings consist of a machined and ground channel-shaped outer ring with a complement of needle rollers retained and guided by a cage. The high-strength cage retains and guides the rollers. An optional lubrication groove and hole in the outer ring facilitate relubrication.These bearings can be used with or without a machined and ground inner ring, depending on the suitability of the shaft as a raceway surface.

Sizes: Metric: 80 mm - 175 mm bore (3.1496 in. - 6.88976 in.).

Markets: Gear pumps, sheaves, automotive transmissions and two-cycle engines.

Features: Thick outer ring provides maximum load capacity and shock resistance
with a relatively small radial cross section.

Benefits: Optimum speed and lubrication-retention capability.
