INA FAG is extending its premium X-Life bearings range with new needle roller bearings up to a maximum 120mm outside diameter. X-Life precision machined needle roller bearings offer dynamic load ratings some 13% higher than standard products, lower running temperatures (due to reduced friction) and a service life extension of up to 50%. These benefits have been achieved by paying close attention to the geometric accuracy of the machined needle roller bearing raceways, and ensuring minimum surface roughness.
