Product Description

Needle roller bearings contain many slender rollers with a length 3 to 10 times their diameter. Therefore, the ratio of the bearing outside diameter to the inscribed circle diameter is small, and they have a rather high radial load capacity. There are numerous types available, and many have no inner rings. The drawn-cup type has a pressed steel outer ring and the solid type has a machined outer ring. There are also cage-and-roller assemblies without rings. Most bearings have pressed steel cages, but some are without cages.
