- Variable stroke material feeding mechanisms
- Semiconductor wafer handling robots
- Pharmaceutical blister packaging machines
- Automated optical inspection systems
Operational note:
Achieve optimal performance by maintaining 0.3-1.0 MPa lubrication pressure.
For vertical installations, use counterbalance valves when handling loads >2kg.
Alignment tolerance: ≤0.2mm/meter in lateral loading conditions.
