High-performance ISO cylinder with double-acting operation, featuring precision-ground stainless steel guide bushings for minimal friction. The hard-anodized barrel incorporates wear-resistant strips for extended service life. Designed for heavy-duty industrial applications requiring precise linear motion control over long strokes.
- Automated press machinery (stamping/bending operations)
- Automotive assembly line clamping systems
- Plastic injection molding machine ejectors
- Material handling equipment (conveyor gate actuators)
- Die casting machine core-pull mechanisms
Installation recommendations:
Use with 40μm filtered air and ISO VG32 hydraulic oil mist lubrication (1 drop/m³).
Allow minimum 20mm lateral clearance for thermal expansion.
For vertical mounting, install rod-down orientation with flow control valves.
- 5,000km theoretical stroke life (clean air conditions)
- Replace seals after 2 million cycles or 3 years (whichever comes first)
- Rod bearing replacement interval: 10 million cycles
