The AirTAC AirTAC SDA80X65S Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 65mm 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 SDA80X65S is a double-acting, single-rod compact cylinder engineered to deliver substantial thrust within a minimal axial footprint. By utilizing a riveted assembly that integrates the barrel, rear cover, piston, and rod, this unit achieves an exceptionally short overall length compared to conventional round-body designs, saving valuable machine mounting depth. It provides a robust 2513.3 N push force and 2267.8 N pull force at 0.5 MPa, operating efficiently at speeds between 30 and 500 mm/s.
This specific configuration includes a built-in piston magnet (indicated by the S code) for direct compatibility with AirTAC reed or electronic switches, which seat neatly into the grooves around the body. The 80 mm bore dictates a 25 mm piston rod and PT3/8 air ports. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable cushion, meaning operators should incorporate external shock absorbers or slow the approach speed when cycling heavy loads at high velocities.

Drives the ejection plate inside a plastic injection molding machine, utilizing the 2513.3 N thrust to cleanly strip finished parts from the mold cavity within a tight press footprint.
Actuates a heavy-duty vertical lift mechanism in end-of-line packaging systems, raising 128 kg payloads with a 2:1 safety margin while the compact body conserves vertical space.
Positions lower die tooling on an industrial metal press brake, using the 65 mm stroke to shift heavy dies rapidly into the working zone without consuming excessive machine length.
Selecting the SDA80X65S provides a computed safe working load of roughly 1508 N (about 60% of its 2513.3 N push capacity at 0.5 MPa), translating to a vertical lift capability of approximately 128.1 kg with a 2:1 safety margin. If your application requires less force, stepping down to the SDA63 yields 1558.6 N of push at 0.5 MPa, whereas moving up to the SDA100 provides 3927 N for heavier demands. Keep in mind that a standard double-acting cylinder like this will drift and cannot hold a load if air pressure is lost or the valve is centered; maintaining vertical loads securely requires an external rod lock or a pilot-operated check valve. When ordering, confirm the 80 mm bore, 65 mm stroke, PT3/8 port, female M14x1.5 rod thread, and the required magnetic sensor option.
Quick checklist
This 80 mm bore double-acting cylinder generates 2513.3 N of push force and 2267.8 N of pull force 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. It operates within a pressure range of 0.15-1.0 MPa, has a proof pressure of 1.5 MPa, and functions in temperatures from -20 to +70 C.
No, end-of-travel deceleration relies on a fixed NBR bumper, not a field-adjustable air cushion, so external shock absorbers are recommended for high-energy stops. Additionally, it does not lock or hold position; the piston drifts if air is lost, requiring an external rod lock for load holding. The S suffix denotes a built-in magnet for AirTAC reed or electronic switches.
