- Semiconductor wafer handling robots
- Optical measurement equipment stages
- 5-axis machining center trunnions
- Medical CT scanner gantries
Installation note:
Requires torque-controlled tightening (8.8Nm ±10%) using M6 mounting screws.
Lubricate with ISO VG32 grease before initial operation. Avoid thermal expansion
by maintaining ≤0.02mm/m temperature gradient during installation.
