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 note:
Requires rigid mounting structure due to high thrust forces. Maintain 0.5° maximum angular misalignment during installation. For vertical mounting, install rod end downward to prevent condensate accumulation. Use locknuts (not included) with torque ≥650 N·m.

Industrial-grade heavy-duty cylinder designed for high thrust applications requiring precise stroke adjustment. Features hardened steel construction with corrosion-resistant surface treatment (electrophoretic coating). The dual adjustable cushions minimize impact at stroke ends, while the oversized piston rod enhances buckling resistance in long-stroke configurations.
Typical Applications:
- Press machine ejection systems
- Shipbuilding plate bending equipment
- Steel coil handling manipulators
- Hydraulic press conversion projects
- Mining conveyor tensioning mechanisms
Installation note:
Requires rigid mounting structure due to high thrust forces. Maintain 0.5° maximum angular misalignment during installation. For vertical mounting, install rod end downward to prevent condensate accumulation. Use locknuts (not included) with torque ≥650 N·m.
Fluid requirements:
ISO 8573-1:2010 Class 3.4.3 compressed air with 5-10μm filtration. Lubricator recommended (ISO VG32 pneumatic oil) for extended seal life.
