- Clamping force adjustment in CNC fixture systems
- Packaging machine stopper positioning
- Semiconductor wafer handling robots
- Printing press pressure control mechanisms
Operation tip:
For optimal performance, lubricate adjustment threads monthly with ISO VG32 hydraulic oil.
Always unlock the adjustment collar (rotate counterclockwise) before position adjustment,
then re-tighten to 0.8-1.2N·m torque after setting.
Critical note:
Avoid partial stroke operation exceeding 8 hours continuously.
Maximum side load capacity reduces by 15% when operated at minimum stroke (25mm).
