High-precision crossed roller guide featuring 45° contact angle rollers for simultaneous radial and axial load handling. The R36 suffix indicates medium preload configuration optimized for vibration damping in heavy cutting applications. Hardened raceways (HRC 58-62) ensure extended service life under 24/7 operation.
- CNC gear grinding machine Z-axis positioning
- Semiconductor wafer handling robots
- Optical lens polishing equipment stages
- High-speed PCB drilling machine slides
- Automotive cylinder boring tool guides
Installation protocol:
Requires granite surface plate alignment (≤0.01mm/m flatness) and 6.8Nm torque for M5 mounting screws.
Always install wiper seals facing away from contamination sources. Thermal expansion compensation needed for
installations exceeding 1.5m rail length.
