Used where rotation accuracy matters: the outside diameter and the spigot are turned in one pass, so concentricity comes from turning and face runout stays within 0.03 mm.
Six equally spaced holes let the cap be clocked to suit the grease nipple.
Round Bearing End Cover
Outside diameter and spigot turned in one pass for concentricity, face runout held within 0.03 mm; six holes let the cap be clocked to the grease point.
