High-rigidity crossed roller guide featuring 90° V-groove design for simultaneous radial and axial load support. The alternating orthogonal roller arrangement eliminates clearance while maintaining smooth motion (friction coefficient μ<0.003). Includes pre-loaded rollers for zero-backlash operation, with hardened raceways (HRC58-62) for extended service life.

Installation note:
Requires mounting surface flatness <0.02mm/m. Use M4x8mm SHCS (12.9 grade)
at 50-60N·m torque. Apply ISO VG32-way oil during assembly. Avoid angular
misalignment exceeding ±0.05° to prevent premature wear.
