The MDJ series adjustable cylinder features a unique stroke adjustment mechanism with positive mechanical stops, enabling precise end-position control without external sensors. Its double-wall construction enhances heat dissipation, while the chrome-plated piston rod provides exceptional corrosion resistance. The dual adjustable cushions minimize impact noise and vibration at stroke ends.
- Precision workpiece positioning in CNC loading systems
- Variable stroke applications in packaging machinery
- Tool height adjustment in automated assembly lines
- Clamping force regulation in fixture design
- Position-sensitive sorting mechanisms
Installation note:
For optimal performance, maintain 0.5-1mm clearance between adjustment screws during installation.
Lubricate adjustment threads with molybdenum disulfide grease if frequently readjusted.
Maximum side load capacity: 15N (use guided cylinders for higher side load requirements).
- Loosen lock nut using 8mm wrench
- Rotate adjustment screw (clockwise to decrease stroke)
- Test stroke with 0.3MPa air pressure
- Re-tighten lock nut to 1.2N·m torque
