Detailed description
CRBF108AT, CRBF108AT UU cross roller bearing belongs to high stiffness type slewing ring, because its inner and outer ring are solid one-piece. And due to its compact structure, CRBF108AT crossed roller bearing can minimize the mounting errors. Besides, it's suitable for both inner ring and outer ring rotation, and do not need mounting plate during installation cause it can be bolted to the related parts directly through its mounting holes.
CRBF cross roller bearings can take radial/axial loads and tiling moment at the same time.
