- Pharmaceutical blister packaging linear actuators
- Semiconductor wafer inspection stages
- 3D printer X/Y axis systems requiring <5μm repeatability
- Laboratory automation liquid handling systems
Mounting protocol:
Apply 25-30N·m torque on rail fasteners using cross-pattern tightening sequence.
Maintain 0.02mm/m straightness tolerance during installation. Lubricate with ISO VG32
grease through 4 zerk fittings (included) before initial operation.
