Description
1. ISO 15552 and VDMA 24562 compliant cylinder design;
2. Asymmetric bidirectional piston seal structure with compact dimensions and integrated oil reservoir function;
3. Rodless square aluminum tubing construction enhances corrosion resistance;
4. Adjustable cushioning mechanism ensures smooth stroke modulation;
5. Customizable configurations with multiple cylinder variants and mounting accessories;
6. High-temperature resistant sealing materials enable operational range of 0-150°C.
Category: Adjustable Cylinders | Brand: AirTAC | Series: SEJ
Installation note:
Use thread locker on adjustment nuts. Maintain 0.5-1mm clearance between
stopper and cylinder end during stroke adjustment. Lubricate rod weekly
with ISO VG32 hydraulic oil in high-cycle applications.
Critical parameters:
Maximum side load ≤25N. Do not exceed 1.0MPa pressure when using
magnetic sensor version. Avoid rapid pressure changes (>0.5MPa/sec).
