High-precision adjustable stroke cylinder with dual cushion control, featuring a chromium-plated piston rod and aluminum alloy barrel. The unique tapered cushion design reduces impact noise by 15dB compared to standard models. Includes magnetic piston for position sensing compatibility. Requires ISO VG32 hydraulic oil mist lubrication for extended seal life.
- Variable position pressing systems in automotive welding lines
- Adjustable clamping mechanisms for CNC fixture tables
- Packaging machine stroke adjustment stations
- Die-casting machine ejection systems requiring precise stroke control
Installation Guidelines:
Maintain 0.05-0.1mm clearance between rod end and load during alignment.
For vertical mounting, install speed controller on lower port.
Cushion adjustment screws require clockwise rotation (max 1.5 turns) for optimal deceleration.
