Precision-engineered adjustable stroke cylinder featuring a unique dual cushioning system and ±0.5mm stroke repeatability. The hardened piston rod and triple-lip seal design ensure leak-free operation in high-cycle applications. Integrated magnetic piston allows for position feedback when used with external sensors. Optional auto-stop mechanism prevents over-extension beyond set stroke.
- Variable height positioning in automated packaging lines
- Clamping force adjustment in CNC fixture systems
- Precision web tension control for printing machinery
- Automotive welding jigs requiring stroke fine-tuning
- Plastic injection molding ejector systems
- Food processing equipment with cleanroom requirements
1. Use locknuts (not included) on adjustment screws after stroke setting
2. Maintain 0.5-1mm clearance between cushion needle valve and end cap during adjustment
3. Lubricate with ISO VG32 hydraulic oil if operating below 0.3 MPa
4. For vertical mounting, install rod-down orientation to prevent seal wear
- Relubricate every 500,000 cycles (standard conditions)
- Replace cushion seals every 2 million cycles
- Magnetic sensor compatibility: 20-30VDC, 2-wire PNP/NPN configurable
