Precision-engineered adjustable stroke cylinder featuring a unique mechanical stopper system for millimeter-level positioning control. The double-rod design provides balanced force distribution and enables position feedback integration. Anodized surface treatment enhances corrosion resistance in humid environments. Includes magnetic piston for sensor mounting (non-magnetic version available).
- Precision clamping fixtures in CNC machining centers
- Variable stroke press mechanisms in packaging lines
- Position-adjustable stops in automotive assembly jigs
- Material handling systems requiring force modulation
- Printing machinery with variable sheet sizes
Installation recommendation:
For optimal performance, maintain 0.5-1mm clearance between stopper screws during adjustment.
Lubricate with ISO VG32 hydraulic oil if used in high-cycle applications (>5 cycles/sec).
Avoid lateral loading exceeding 30N.
