CRBC Crossed Roller Bearings CRBC25040

CRBC Crossed Roller Bearings CRBC25040

The CRBC25040 is a crossed roller bearing with a 250mm bore and 355mm outer diameter, designed for combined loads. Its compact 40mm width and steel construction make it sturdy yet space-efficient.

With a basic load rating of 195 kN, it handles heavy loads smoothly, while the open design allows easy lubrication. The bearing operates well in temperatures from 0°C to 110°C.

Its press-fit shaft mount ensures a secure installation, and the ABEC5 rating (upgradable to ABEC7/9) offers precision for demanding applications. The crossed roller design provides stability under combined loads.

Ideal for industrial machinery, robotics, or precision equipment where space and load capacity matter. Compliant with RoHS and REACH standards, it weighs 14.8kg for its robust size.
