Ordering NSK bearings: what we need

Give the complete designation marked on the bearing, including prefix and suffix letters such as seal, cage, clearance and precision codes. If the marking is worn, measure bore, outside diameter and width and tell us the machine and shaft position, the operating speed and the lubrication. State the quantity and any precision class or special clearance required.
