High-torque industrial cylinder designed for heavy-duty automation applications. Features dual sealing system with integrated wiper ring to prevent particulate ingress. The precision-machined barrel ensures ≤0.05mm ovality tolerance. Optional magnetic piston version (SI125X350N-M9) available for position sensing.
- Automotive assembly line clamping mechanisms
- Steel mill material handling systems
- Injection molding machine ejectors
- Palletizing robot end-effectors
- Hydraulic press synchronization systems
Installation guidelines:
Maintain 0.1–0.3mm alignment tolerance during mounting. Use flexible couplings
when lateral forces exceed 15% of maximum thrust. Lubricate rod weekly with ISO VG32
hydraulic oil in high-cycle applications (>500,000 cycles/month).
Critical note:
Requires 5μm filtered compressed air with dew point ≥3℃ below ambient temperature.
Avoid extended partial stroke operation below 0.3MPa to prevent seal wear acceleration.
