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 tip:
Use vibration-resistant locknuts (Class 8.8 or higher) for mounting.
Maintain 0.5-1mm clearance between stopper and cylinder body during adjustment.
Requires 40μm filtered air with ISO VG32 hydraulic oil mist lubrication.
