Machined needle roller bearings 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. X-life Various sizes are supplied in the X-life grade. These bearings are indicated in the dimension tables. 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. X-life Various sizes are supplied in the X-life grade. These bearings are indicated in the dimension tables.
