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.
