INA machined needle roller bearings are used when the load carrying capacity or accuracy of drawn cup needle roller bearings with open ends is no longer sufficient and the high load capacity of cylindrical roller bearings is not yet required.

Standard bearings are available as - needle roller bearings with ribs, with or without inner ring, and needle roller bearings without ribs, with or without inner ring.

Bearings without an inner ring are highly suitable for bearing arrangements with particularly compact radial dimensions, if the shaft raceway can be hardened and ground.

Bearings with an inner ring are used if the shaft cannot be configured as a rolling bearing raceway.

With an improved surface quality, the load ratings of X-life needle roller bearings have been increased even further. The dynamic load rating could be increased by 13 % compared to the previous needle roller bearings. The substantially improved load ratings lead to higher-performance bearings with a longer service life, reduced lubricant load, reduced friction and lower bearing temperatures. The benefits stemming from all of these developments include greater efficiency for your applications and a much better price-to-performance ratio.
