The AirTAC SDA80X65B 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 SDA80X65B 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 an exceptionally short axial package, drastically reducing mounting depth where a conventional round-body unit would not fit. The hard-anodized bore ensures durability across the 30-500 mm/s speed range.
This specific SKU includes a male M22x1.5 threaded piston rod end for robust mechanical coupling to your load. End-stopping is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning high-energy cycles may require an external shock absorber to prevent impact damage. Because this configuration lacks the -S magnet option, it cannot directly host AirTAC reed or electronic switches.

Drives heavy plastic part ejection plates within tight machinery cavities, leveraging the 2513.3 N extend force to break parts free without requiring excessive axial envelope space.
Indexes thick gauge steel stock into a mechanical press, utilizing the 25 mm male-threaded rod to securely attach heavy gripping jaws while operating at speeds up to 500 mm/s.
Raises and lowers a 128 kg conveyor pallet payload vertically, relying on the compact riveted body to fit within strict vertical lift station footprint constraints.
When sizing this 80 mm bore actuator, consider stepping down to the SDA63, which yields 1558.6 N of push at 0.5 MPa, or scaling up to the SDA100 for 3927 N at the same pressure. To finalize your order, confirm the 65 mm stroke, PT3/8 port, male M22x1.5 rod thread, and the absence of a sensor magnet. Remember that a standard compact cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates the stroke end and does not function as a locking brake. If your application demands position holding without live pressure, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This 80 mm bore double-acting cylinder generates 2513.3 N of push and 2267.8 N of pull at 0.5 MPa. At 0.7 MPa, the push increases to 3518.6 N and pull to 3175 N. The theoretical maximum push is 513 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, with a proof pressure of 1.5 MPa, and functions in temperatures from -20 to +70 C.
No, end-of-stroke deceleration is provided solely by fixed NBR bumpers, not field-adjustable air cushions; high-speed applications should use external shock absorbers. Additionally, this specific SKU lacks the -S piston magnet, so it cannot support AirTAC reed or electronic switches without changing to an -S variant.
