BTR series high-speed angular contact thrust ball bearings

Ball screw support bearings

Integrating angular contact and thrust structures, these bearings withstand combined axial and radial loads and adapt to high-speed operation. They run smoothly with high rigidity and low friction, effectively controlling temperature rise. Mainly used for machine tool spindles, precision transmission devices and high-speed rotating mechanisms with strict requirements on speed and load capacity.
