- Die-casting machine ejection systems
- Plastic injection molding machine part extractors
- Automotive welding fixture positioning
- Packaging machine vertical lift systems
Installation guidelines:
Align cylinder axis within 0.2mm angular misalignment tolerance.
Lubricate with ISO VG32 hydraulic oil if using non-lubricated air.
For vertical mounting, install rod-down orientation to prevent seal wear.
