Product Description

Needle Roller Bearings NA Series The designs provide maximum cage strength consistent with the inherently high load ratings of needle Roller Bearings. Accurate guidance of the needle rollers by the cage bars allows for operation at high speeds. Also available are needle roller and cage assemblies using molded. Drawn Cup Needle Roller Bearings with closed ends and open ends are obtainable in open and closed variants. Owing to the thin-walled external drawn cup and the lack of an internal ring, drawn cup needle roller bearings with a closed end and open ends have a very low radial section height. They contain extremely high load carrying ability, are appropriate for high velocities and can be effortlessly fixed. If snap rings, shoulders, etc., are not used for axial location, the housing bore can be shaped effortlessly and in particular economical.

Drawn Cup Needle Roller Bearings NA

Drawn Cup Needle Roller Bearings NA combine high radial load carrying capability with low cost.
The inward-turned lips of the cup mechanically retain the optimum number of needle rollers. This feature provides positive radial retention even in applications where repeated shaft removal and reinstallation may be necessary.

Full Complement Needle Roller Bearings NA offer very high load-carrying capabilities, while minimizing required cross section
In certain applications, we can replace a caged bearing with a full complement bearing to provide greater power density.
