Precision-engineered miniature cylinder featuring micro-positioning capability through its unique 50mm mechanical stroke adjustment. The dual-cushion design with progressive damping ensures smooth end-of-stroke deceleration. Anti-rotation piston rod and integrated mounting slots enable stable linear motion in space-constrained applications. Compatible with position sensors (Hall effect or reed switch types).
- Precision fixture positioning in CNC machining centers
- Variable stroke mechanisms in semiconductor handling robots
- Adjustable clamping systems for PCB assembly lines
- Medical device actuation requiring cleanroom compatibility
- Packaging machine product ejection with variable heights
Installation guidelines:
- Align cylinder axis within 0.2mm parallel tolerance
- Apply silicone-free lubricant (ISO VG32) to rod before initial use
- Limit side load to ≤15% of maximum thrust capacity
- Perform cushion adjustment at 50-70% of maximum operating pressure
