The SEJ series incorporates a unique stroke adjustment mechanism with ±5mm fine-tuning capability via locking nuts, enabling precise positioning without external sensors. Its anti-rotation design maintains alignment in multi-cylinder setups.
- Variable position clamping in CNC fixture systems
- Adjustable press mechanisms in packaging lines
- Material handling with position-sensitive gripping
- Printing machinery with variable sheet sizes
- Automated assembly requiring stroke flexibility
Installation note:
For optimal performance, align cylinder axis within 0.2mm parallel deviation.
Lubricate with ISO VG32 turbine oil before initial operation. Adjust cushion screws
while pressurized for precise deceleration tuning. Regular maintenance every
500,000 cycles recommended.
