Precision-engineered adjustable stroke cylinder featuring dual-position magnetic sensor slots for flexible automation setups. The enhanced rod guidance system reduces lateral load stress, while the double-lip rod seal ensures leak-free operation in high-cycle applications. Requires ISO VG32 hydraulic oil mist lubrication for optimal performance.
- Variable height work platforms in assembly lines
- Clamping force adjustment in CNC fixturing
- Precision web tension control in printing machinery
- Modular robotic end effector positioning
- Batch-specific stroke adjustment in packaging systems
Installation protocol:
Align cylinder axis within 0.2mm perpendicularity tolerance.
For adjustable stroke applications, tighten stopper bolts to 12-15N·m torque
and verify position with limit switches before operation.
Maintenance alert:
Replace cushion seals every 500,000 cycles in continuous duty applications.
Never exceed 1,200mm/s piston speed without consulting factory engineers.
