High-precision adjustable stroke cylinder featuring position detection capability through built-in magnetic sensor (reed switch). The gold-anodized barrel provides enhanced corrosion resistance for humid environments. Unique dual-scale stroke adjustment mechanism allows ±5mm fine-tuning via rotating end caps, with visual stroke indicators on both sides.
- Precision clamping fixtures in CNC machining centers
- Variable height positioning in automated assembly lines
- Material handling systems requiring force adjustment
- Packaging machinery with dynamic stroke requirements
- Plastic injection molding ejector mechanisms
Installation note:
For optimal sensor performance, maintain 1-2mm gap between cylinder and ferrous mounting surfaces.
Lubricate adjustment threads monthly with ISO VG32 hydraulic oil in high-cycle applications.
- Loosen both lock nuts (clockwise rotation)
- Rotate end caps - left for front stroke, right for rear position
- Align desired stroke value with reference marks
- Re-tighten nuts to 1.5-2.0 N·m torque
