- Packaging machine clamping/positioning
- CNC machine tool actuation
- Automotive assembly line tooling
- Electronics component press-fit operations
Installation note:
Align cylinder axis within 0.2mm perpendicular tolerance. Apply ISO VG32 hydraulic oil
or equivalent for initial lubrication. Buffer adjustment requires 10-15 test cycles
after installation.
