PRECISION COMBINED ROLLER BEARINGS - DIMENSIONS

These precision combined roller bearings have a larger outer diameter than the Standard Combined Roller Bearings & are designed to be used in conjunction with precision profiles. The precision comes from the tighter clearance (0.2mm) between the bearing & channel.
