A high-performance industrial cylinder featuring precision honed tubing and dual anti-rotation guides. The SI63X70 combines optimized flow characteristics with low friction seals, delivering smooth operation across 1 million+ cycles. Its modular design allows easy integration with magnetic sensors (separately available) for position feedback.
- Automated assembly line clamping mechanisms
- Packaging machine ejection systems
- Plastic injection molding machine part extractors
- Material handling lift-and-position units
- Textile machinery tension control systems
Installation note:
Lubricate through air ports before initial use. For vertical mounting,
use locknut accessories to prevent rod rotation. Maintain 0.5–1mm
alignment tolerance during bracket installation.
Requires 40μm filtered air with ISO
VG32 turbine oil mist lubrication (1 drop/m³). Avoid side-load forces
exceeding 15% of max thrust capacity.
