PRECISION COMBINED ROLLER BEARINGS (PR4.0xx)

standard combined roller bearing

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.

If this level of precision is not required, then please look at our standard range. Calculate which size you need using Hertzian Pressure.
