- Variable position clamping in CNC fixtures
- Material handling with fragile components
- Packaging machine stopper mechanisms
- Automated test equipment positioning
Installation note:
Adjust cushion screws incrementally (1/4 turn per adjustment) while monitoring stroke performance.
Lubricate with ISO VG32 hydraulic oil before initial use. Maintain 0.3–0.5 MPa air pressure during
cushion adjustment for optimal results.
Avoid lateral loads exceeding 30N. For vertical mounting,
use guide mechanisms when payload exceeds 5kg. Cushion adjustment range varies with operating pressure -
re-calibrate after pressure changes.
