The AirTAC AirTAC SDA80X25H Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 25mm 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 SDA80X25H is a double-acting single-rod compact cylinder engineered for heavy-duty operations within confined axial footprints. Utilizing a riveted body assembly, it achieves a remarkably short overall length compared to conventional round-body units, saving valuable machine mounting depth. This specific SKU features an 80 mm bore, a robust Ø25 mm piston rod, and PT3/8 air ports, generating 2513.3 N of push force at 0.5 MPa. Equipped with fluororubber (FKM) seals, it is tailored for environments requiring enhanced temperature and oil resistance.
Deceleration at stroke endpoints is managed by a fixed NBR bumper rather than an adjustable air cushion, meaning external shock absorbers should be specified for high-energy cycles. Because this configuration lacks the -S magnet option, it cannot host magnetic reed or electronic switches. The compact body excels in short-stroke applications, offering a safe working load of roughly 1508 N (about 60% of the 0.5 MPa push figure) and a vertical lift capacity of approximately 128.1 kg with a 2:1 safety margin.

Drives short-stroke ejection pins in automotive injection molding presses, utilizing the 2513.3 N push force to break heavy plastic parts free from tight tooling cavities.
Acts as a compact press ram in sheet metal fabrication lines, delivering precise 25 mm strokes to form thick aluminum brackets without consuming excessive machine length.
Controls heavy-load stopper gates on end-of-line palletizing robots, using the Ø25 mm rod and FKM seals to withstand harsh industrial environments and high kinetic impacts.
When sizing this 80 mm bore actuator, evaluate your force requirements carefully. Stepping down to the SDA63 yields 1558.6 N of push at 0.5 MPa, whereas scaling up to the SDA100 provides 3927 N. The SDA80X25H strikes a balance with 2513.3 N at 0.5 MPa, extending to 3518.6 N at 0.7 MPa, making it ideal for medium-to-heavy tasks. Confirm your ordering essentials: 80 mm bore, 25 mm stroke, PT3/8 port, female M14x1.5 rod thread, and FKM seals.
Remember that a standard compact cylinder will not maintain its position if air pressure drops or the directional valve is centered. The piston will drift, as the fixed bumper only decelerates the rod near the end of its travel and acts purely as an end stop, never as a locking mechanism. If your application demands strict load holding on air loss, you must integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
Quick checklist
This 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, with an operating pressure range of 0.15-1.0 MPa.
No, this specific SKU does not include the -S piston magnet, so it cannot host AirTAC reed or electronic switches. Additionally, it relies on a fixed NBR bumper to decelerate at the ends rather than an adjustable air cushion, so you should slow the approach or add external shocks for high-speed loads.
