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 guidelines:
Requires minimum 2x bore size clearance for stroke extension. Use M20x1.5 mounting bolts (grade 8.8 or higher).
Lubricate through integrated grease nipple (NLGI #2) every 500km of stroke travel.
Critical note:
Maximum side load 2,800N at mid-stroke. For vertical mounting, always install mechanical lock at stroke end.
Not suitable for vacuum applications below -0.8 bar.
