The AirTAC AirTAC SDA80X65 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 SDA80X65 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 achieves an exceptionally small axial footprint. This space-saving architecture is ideal for machinery where a traditional round-body cylinder would simply demand too much mounting depth.
This specific 80 mm bore model features a robust 25 mm piston rod and PT3/8 air ports, coupling securely to heavy loads via a female M14x1.5 rod-end thread. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning operators should slow the approach or add an external shock absorber for high-energy cycles. Furthermore, this base SKU lacks a piston magnet, so it cannot directly host magnetic position sensors.

Provides robust stripping force to eject dense plastic automotive interior panels from heavy molds, utilizing the 65 mm stroke to clear the tooling safely.
Pushes thick gauge steel blanks into a mechanical press alignment fixture, where the 2513.3 N output ensures positive seating before the stamping cycle begins.
Actuates a heavy diverter gate on a packaging line, taking advantage of the compact riveted body to fit within the tight vertical envelope of the conveyor frame.
When sizing this model, evaluate your force requirements carefully. Stepping down to the SDA63 yields 1558.6 N of push at 0.5 MPa, whereas stepping up to the SDA100 provides 3927 N. The SDA80X65 provides a computed safe working load of roughly 1508 N (about 60% of its 0.5 MPa capacity) and can vertically lift approximately 128.1 kg with a 2:1 safety margin.
Remember 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; the fixed bumper only decelerates the piston near stroke end and acts as neither a lock nor a brake. For suspended loads, integrate an external rod lock or a pilot-operated check valve. To order, confirm your essentials: 80 mm bore, 65 mm stroke, PT3/8 port, female rod thread, and no sensor magnet.
Quick checklist
At 0.5 MPa, this 80 mm bore cylinder provides 2513.3 N of push force and 2267.8 N of pull force. At 0.7 MPa, push increases to 3518.6 N and pull to 3175 N. The theoretical maximum push force is 513 kgf at 1.0 MPa.
No, this specific SKU does not include a piston magnet, so it cannot host reed or electronic switches. You would need the SDA80X65S variant for position sensing. Additionally, end stops rely on a fixed NBR bumper, not an adjustable air cushion.
