Precision-adjustable cylinder featuring a unique dual-stroke design with mechanical stroke limiter. The 30mm fine-tuning range allows millimeter-level positioning accuracy through its hex socket adjustment screws (M8×1.25 pitch). Integrated shock absorption reduces end-impact noise by 40% compared to standard cylinders. Optional magnetic piston version (SAUJ50X85-30-M) available for position sensing.
- Die-casting machine ejection force control
- PCB drilling equipment depth adjustment
- Automotive welding fixture positioning
- Textile machinery tension control systems
- Glass cutting line pressure regulation
Installation note:
Adjustable end must face accessible side for maintenance. Use locknut (included) after stroke adjustment.
Avoid side-load exceeding 30N. For vertical mounting, install rod-end down to prevent contaminant accumulation.
- Re-lubricate every 6 months using ISO VG32 hydraulic oil
- Inspect cushion seals every 5,000 cycles in high-speed applications
- Maximum side load: 1/20 of piston thrust
- Storage humidity: ≤85% RH (non-condensing)
