Industrial-grade adjustable stroke cylinder featuring heavy-wall steel construction with corrosion-resistant treatment. The double-acting design incorporates a unique stroke adjustment mechanism with positive locking nuts, allowing ±25mm fine-tuning without disassembly. High-load capacity design supports 25% greater side moment resistance compared to standard models. Requires ISO 8573-1:2010 Class 3-4-3 compressed air quality.
- Die casting machine ejection systems
- Heavy-duty press brake tool positioning
- Automotive welding fixture clamping
- Shipbuilding plate bending equipment
- Mining conveyor tensioning mechanisms
Maintenance advisory:
Apply ISO VG32 hydraulic oil mist lubrication (1:1000 ratio) for optimal seal life.
Perform stroke adjustment only in depressurized state using calibrated torque wrench (85-95 N·m).
