High-precision industrial cylinder featuring dual-side shock absorption and mechanical stroke fine-tuning capability. The hexagonal body design enables easy wrench adjustments during operation. Special piston design achieves ≤0.5mm positioning repeatability. Includes anti-rotation guide mechanism for angular force applications.
- Die casting machine ejection force control
- Automated palletizing position correction
- Glass panel press fitting systems
- PCB drilling equipment depth adjustment
- Automotive welding fixture positioning
Operation Tip:
For optimal performance, rotate the adjustment nuts in 15° increments while monitoring pressure gauge fluctuations.
Always maintain 0.05-0.1mm lubrication gap between cushion seal and end cover. Avoid over-tightening beyond 25N·m torque.
Critical Note:
Requires weekly inspection of cushion needle valve (CW/CCW rotation ≤270°) and monthly lubrication of guide bushings
using ISO VG32 hydraulic oil. Not suitable for side load >150N without external guide.
