Detailed Product Description

Radial Needle roller and cage assemblies(needle roller bearing)

arkets:

 Automotive and truck transmissions,agricultural and construction equipment,two-cycle engines, pumps and compressors.

Features:

 Special coatings and platings; split and segmented designs for simplified mounting;engineered polymer cages. Benefits: High load capacity and high limiting speed within the smallest envelope.

Needle roller and cage assemblies are a complement of needle rollers held in place by a cage. The mating shaft and housing are normally used as inner and outer raceways. The unitized design allows for easy handling and installation. Controlled-contour rollers reduce end stresses and permit operation under moderate misalignment. A variety of cage designs, styles and materials, as well as multiple roller paths and segmented constructions, meet broad application requirements.

Needle roller and cage radial assemblies have a steel cage that provides both inward and outward retention for the needle rollers.The designs provide maximum cage strength consistent with the inherent high load ratings of needle roller bearings. Accurate guidance of the needle rollers by the cage bars allows for operation at high speeds. Needle roller and cage assemblies have either one or two rows of needle rollers.Needle rollers with relieved ends used in these assemblies are made of high carbon chrome steel, through-hardened, ground and lapped to close tolerances for diameter and roundness. See the engineering section of this catalog for further discussion of relieved end rollers.
