Ultra-precision crossed roller guide featuring 90° V-groove design for simultaneous absorption of radial and axial forces. Incorporates preloaded rollers with 45° contact angles for zero-backlash operation. Hardened raceways undergo super-finishing (Ra 0.2μm) for smooth motion characteristics. Includes integrated lubrication ports and anti-creep design for vertical installations.
