SKF NKXR45 bearing

45x58x32

SKF supplies certain needle roller / thrust ball bearings capped with a stamped steel cover over the thrust part of the bearing (fig. 7, fig. 9, designation suffix Z). The cover, which has no lubrication holes, forms a gap-type seal to retain the grease in the bearing.
