The SI63X340 industrial cylinder features a reinforced piston rod (hardened to HRC 45-50) and low-friction seals for high cycle rates. Its extended stroke design incorporates a wear-resistant guide bushing to prevent side load deflection. The cylinder tube undergoes multi-stage surface treatment including anodic oxidation and particle sealing for corrosion resistance. Requires ISO 8573-1:2010 Class 3-4-3 compressed air.
- Palletizing robot arm actuators
- Plastic injection molding ejectors
- Steel coil handling systems
- Automotive welding fixture positioning
- Paper roll tensioning mechanisms
Installation note:
Optimal performance achieved when mounted horizontally (±5° tolerance). For vertical installations,
use rod-down orientation and specify C95 counterbalance valves. Lubricate via air line lubricator
(ISO VG32 recommended) if cycle rate exceeds 200/min.
