Precision-engineered adjustable stroke cylinder featuring patented position-lock mechanism for stable intermediate stops. The 40mm stroke adjustment range enables micro-positioning through rotating the external collar. Corrosion-resistant construction with IP54 protection rating ensures reliability in harsh environments. Includes built-in magnetic sensor groove (M9x1 thread) for position feedback.
- Precision workpiece clamping in CNC machining centers
- Variable height positioning in automated assembly lines
- Pressure control systems for plastic injection molding
- Adjustable stops in material handling equipment
- Packaging machine product height compensation
 Operation tip: Lubricate with ISO VG32 hydraulic oil before initial use. 
            For fine adjustments, rotate the stroke collar clockwise in 5° increments 
            (each 15° rotation equals 1mm stroke change). Avoid over-tightening beyond 
            the 40mm adjustment limit.
