The AirTAC AirTAC SDA80X50S Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 50mm stroke, PT3/8 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA80X50S is a double-acting single-rod compact cylinder engineered to deliver a substantial 2513.3 N push force at 0.5 MPa. Its riveted assembly merges the barrel, rear cover, piston, and rod into a highly shortened unit, drastically reducing axial mounting depth compared to conventional round-body designs. This space efficiency is critical when integrating heavy actuation into tight machine footprints.
This specific model includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves. The 80 mm bore pairs with a robust 25 mm piston rod and PT3/8 ports. End-stopping relies on a fixed NBR bumper that decelerates the load; it is not an adjustable air cushion, so high-energy cycles may require external shock absorbers.

Drives heavy mold ejector pins in plastic injection machinery where a 128.1 kg lift capacity and minimal axial length prevent interference with the press platen.
Actuates heavy-gauge metal stock feeders in stamping lines, utilizing the 2513.3 N push force to advance material strips accurately against resistance.
Raises and lowers diverter gates on packaging palletizers, benefiting from the 25 mm rod rigidity and the -S magnet for electronic switch position feedback.
Selecting this 80 mm bore yields a 2513.3 N extend push at 0.5 MPa. If your application requires less force, stepping down to the SDA63 provides 1558.6 N, while moving up to the SDA100 offers 3927 N. A computed safe working load is roughly 1508 N (about 60% of the 0.5 MPa push), allowing a vertical lift of approximately 128.1 kg with a 2:1 safety margin. Confirm your ordering essentials: 80 mm bore, 50 mm stroke, PT3/8 port, female M14x1.5 rod thread, and the integrated magnet.
Keep in mind that a standard compact cylinder drifts when air pressure is lost or the valve is centered. The fixed NBR bumper only decelerates the piston near the stroke end and does not function as a locking brake. If your setup must hold a vertical load without live pressure, incorporate an external rod lock or a pilot-operated check valve.
Quick checklist
This double-acting cylinder generates a push force of 2513.3 N and a pull force of 2267.8 N at 0.5 MPa. At 0.7 MPa, the push increases to 3518.6 N. The theoretical maximum push is 513 kgf at the 1.0 MPa operating pressure limit.
No, it uses a fixed NBR bumper at each end to decelerate the stroke. This is not a field-adjustable air cushion. For high-speed or high-energy loads, you should add an external shock absorber or slow down the approach speed.
