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 protocol:
Always install with 0.5mm minimum alignment tolerance. Lubricate with ISO VG32
pneumatic oil during initial setup. For vertical mounting, add rod-end support
(ASK32 accessory recommended).
Maintenance alert:
Replace cushion seals every 500,000 cycles in high-speed applications
(>500mm/s). Avoid using silicone-based lubricants with HNBR seals.
