Precision-adjustable pneumatic cylinder featuring dual-position mechanical stroke adjustment through rotating end caps. The hexagonal barrel design enables tool-free stroke setting with 0.5mm incremental precision. Corrosion-resistant construction with IP54 protection rating makes it suitable for harsh environments. Includes magnetic piston for sensor compatibility.
- Variable height positioning in automated assembly lines
- Clamping force adjustment in CNC fixture systems
- Precision material feeding devices
- Packaging machine stroke compensation
- Semiconductor handling equipment
 Installation tip: 
            Rotate adjustment dials only when cylinder is depressurized. 
            Recommended maintenance: Relubricate every 500km of cumulative stroke 
            movement using ISO VG32 hydraulic oil.
