Description
1. Compliant with ISO 15552 standard (formerly ISO 6431) for cylinder manufacturing;
2. SG series adopts dual Y-type unidirectional piston seals with self-compensating design, delivering extended service life and low starting pressure. SGC series features space-saving asymmetric bidirectional seals with oil reservoir functionality;
3. SG series utilizes steel cylinder construction with exceptional impact resistance;
4. SGC series employs aluminum cylinder tubes compatible with optional magnetic piston position sensing (not available for SG series);
5. Precision adjustable pneumatic cushioning mechanism ensures smooth deceleration;
6. Comprehensive range of bore sizes and mounting accessories for flexible system integration;
7. High-temperature resistant seals enable reliable operation from 0°C to 150°C.
Category: Standard Cylinders | Brand: AirTAC | Series: SGJ Adjustable Steel Cylinder Series
Installation guidance:
When using stroke adjustment, limit side load to ≤15% of maximum thrust.
Apply thread lock adhesive to stopper bolts after final position setting.
Requires monthly inspection of cushion seal wear in high-cycle applications (>500,000 cycles/year).

Heavy-duty steel cylinder with mechanical stroke adjustment mechanism, featuring wear-resistant chromium carbide piston bands and integrated magnet for position sensing. The cold drawn steel tube construction provides 30% higher rigidity than aluminum models, with anti-corrosion treatment for humid environments. Includes shock-absorbing polyurethane bumpers and 5-position adjustable cushioning.
Industrial Applications:
- Press machine ejection systems (adjustable stroke for varying mold heights)
- Automated foundry equipment (high temperature resistance)
- Paper converting machinery (corrosion-resistant construction)
- Die-casting robot end effectors (vibration-resistant design)
- Heavy load transfer systems (up to 980N thrust @0.5MPa)
Installation guidance:
When using stroke adjustment, limit side load to ≤15% of maximum thrust.
Apply thread lock adhesive to stopper bolts after final position setting.
Requires monthly inspection of cushion seal wear in high-cycle applications (>500,000 cycles/year).
