Thanks to 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.

Needle roller bearings with ribs
Needle roller bearings are single or double-row units comprising machined outer rings with ribs, needle roller and cage assemblies and removable inner rings. The bearings are available in open and sealed designs.

Needle roller bearings without ribs
Needle roller bearings are single or double-row units comprising machined outer rings without ribs, needle roller and cage assemblies and removable inner rings.
The bearings are not self-retaining. This means that the outer ring, needle roller and cage assembly and inner ring can be fitted independently of each other.

Various sizes are supplied in the X-life grade. These bearings are indicated in the dimension tables.
Needle roller/axial ball bearing
Combined needle roller bearings such as needle roller/axial ball bearings are units comprising radial needle roller bearings with a rolling bearing component capable of supporting axial loads

Needle roller/axial cylindrical roller bearings
Needle roller/axial cylindrical roller bearings comprise an outer ring with radial and axial raceways, two shaft locating washers, an inner ring, a radial needle roller and cage assembly and two axial cylindrical roller and cage assemblies. The bearings are available in versions for screw mounting and not for screw mounting.

X-life – proven to be better
In these bearings, the raceways have optimized roughness and geometrical accuracy. This gives a higher load-carrying capacity and longer service life. X-life is the premium brand that identifies particularly high-performance products under the INA and FAG brands.
They are characterized by a longer rating and operating life – the result of higher dynamic load ratings than those of current standard products. If the load and design envelope are unchanged, X-life bearings have a longer rating life. Longer maintenance intervals are possible.
