A high-duty pneumatic cylinder featuring precision honed tube and dual cushioning control. The SI40X260 delivers 502N thrust at 0.6MPa (extend) with ±0.5mm repeat positioning accuracy. Magnetic piston version (SI40X260-M) enables position feedback via sensors. Corrosion-resistant construction allows operation in humid environments when paired with proper air treatment.
- Automated assembly line pallet transfer systems
- Plastic injection molding machine ejectors
- CNC machine tool clamping mechanisms
- Automotive welding fixture positioning
- Packaging machine product pushers
Installation note:
Maintain 0.05–0.1mm alignment tolerance during mounting. For vertical installations,
use rod-down orientation to prevent piston drift. Lubricate through air supply
(ISO VG32 pneumatic oil recommended) if not using non-lube seals.
