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.
Needle roller bearings have a high load carrying capacity in addition to their low cross-section and stiffness. They are especially suitable for bearing arrangements where radial space is limited because needle roller bearings only carry pure radial load and can not limit the axial displacement of shaft relative to the housing. It is important to ensure that inner ring axis and outer ring axis must be aligned during mounting the bearings.
