Ultra-precise crossed roller guide featuring 90° V-groove design for simultaneous control of radial and axial loads. The staggered roller arrangement eliminates clearance while maintaining smooth motion (friction coefficient <0.003). Includes pre-loaded rollers (±0.005mm preload adjustment) and hardened raceways (HRC 58-62) for long-term accuracy retention.
