- Automotive assembly line clamping devices
- Plastic injection molding machine ejectors
- Textile machinery tension control systems
- Food processing equipment (stainless steel version optional)
Installation note:
Requires minimum 1.5× bore size clearance for rod extension.
For vertical mounting, use spring-up orientation to prevent
unintended descent during pressure loss. Lubricate with ISO VG32
hydraulic oil if used in high-cycle (>5,000,000 cycles) applications.
