Needle roller bearings with ribs are single or double row units comprising machined outer rings with ribs, needle roller and cage assemblies and removable inner rings. Needle roller bearings with ribs are X-life bearings. These bearings have optimised raceway surfaces. This gives higher load carrying capacity and longer rating life.
