The AirTAC AirTAC SDA63X60SH Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 60mm stroke, PT1/4 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA63X60SH is a double-acting, single-rod compact cylinder engineered to deliver a substantial 1558.6 N push force at 0.5 MPa. Its short riveted assembly merges the barrel, rear cover, piston, and rod, drastically reducing axial mounting depth compared to conventional round-body units. This space-saving footprint is ideal for tight machine layouts.
This specific configuration includes an -S piston magnet for direct mounting of AirTAC reed or electronic switches along the body grooves, plus an -H fluororubber (FKM) seal for enhanced thermal and oil resistance. End-stopping relies on a fixed NBR bumper rather than an adjustable cushion, meaning external shock absorbers should be added for high-energy 60 mm strokes.

Drives ejection pins on mid-sized plastic injection molding machines, utilizing the 1558.6 N extend force to reliably strip finished parts from tight tooling enclosures.
Folds heavy corrugated cardboard flaps on automated packaging lines, where the 60 mm stroke and FKM seals withstand continuous high-speed cycling and lubricant exposure.
Actuates diverter gates on palletizing conveyors, lifting and lowering product flows with a 79.4 kg vertical lift margin while fitting into shallow frame clearances.
Selecting this 63 mm bore provides a safe working load of roughly 935 N (about 60% of the 1558.6 N push at 0.5 MPa), translating to a vertical lift capacity of approximately 79.4 kg with a 2:1 safety margin. If your application requires less force, the SDA50 offers 981.7 N at 0.5 MPa; stepping up to the SDA80 yields 2513.3 N for heavier demands. Remember that a standard compact cylinder drifts when air is lost or a valve centers—the fixed bumper only decelerates near stroke end, so an external rod lock or pilot-operated check valve is required to hold a load securely. When ordering, confirm the 63 mm bore, 60 mm stroke, PT1/4 port, built-in magnet (S), FKM seals (H), and the female M10x1.5 rod thread.
Quick checklist
This double-acting cylinder generates a push force of 1558.6 N and a pull force of 1401.5 N at 0.5 MPa. At 0.7 MPa, the push increases to 2182.1 N. The theoretical maximum push is 318 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, runs at 30-500 mm/s, and handles temperatures from -20 to +70 C.
No, a plain SDA cylinder will drift downward if air pressure is lost or the directional valve is centered. The fixed NBR bumper at each end only decelerates the piston near the stroke limits; it does not act as a locking brake. To maintain a vertical position safely, you must install an external rod lock or a pilot-operated check valve.
