The AirTAC SDA80X30S Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 30mm 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 SDA80X30S is a double-acting single-rod compact cylinder engineered to deliver a substantial 2513.3 N push force at 0.5 MPa. By utilizing a short riveted body that permanently joins the barrel, rear cover, piston, and rod, this unit drastically reduces axial mounting depth compared to conventional round-body cylinders. This space-saving footprint is critical when integrating heavy push force into tight machine envelopes.
This specific model includes a built-in piston magnet (the S option) for direct compatibility with AirTAC magnetic reed or electronic switches, which seat neatly into the grooves around the body. End-stopping relies on a fixed NBR bumper rather than an adjustable air cushion, meaning high-energy cycles may require an external shock absorber to prevent wear. The 25 mm piston rod features a female M14x1.5 thread, and the PT3/8 air ports ensure high flow for rapid actuation.

Provides the robust 2513.3 N push force required to eject dense plastic parts from injection molding dies where axial mounting space is severely restricted.
Drives short-stroke press brakes or bending jigs for thick sheet metal, utilizing the 30 mm stroke and fixed NBR bumpers to absorb repeated high-energy end stops.
Actuates heavy pallet lifting forks in packaging lines, where the built-in S magnet enables reed or electronic switches to confirm lift heights precisely.
When sizing this 80 mm bore actuator, evaluate your force requirements carefully. Stepping down, the SDA63 provides 1558.6 N of push at 0.5 MPa, which may suffice for lighter duties. Stepping up, the SDA100 yields 3927 N at 0.5 MPa for heavier loads. Confirm your ordering essentials: 80 mm bore, 30 mm stroke, PT3/8 port, female rod thread, and the built-in magnet.
Remember that a plain compact cylinder does not hold its position if air pressure is lost or the valve is centered; the piston will drift, and the fixed NBR bumper only decelerates the stroke end rather than locking it. If your application must hold a load without live pressure, you must integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
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 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa.
No, the SDA80X30S uses a fixed NBR bumper at each end to decelerate the piston, not an adjustable air cushion. For high-speed or high-energy cycles, you should slow the approach speed or add an external shock absorber to protect the equipment.
