The AirTAC AirTAC SDA25X80H Compact Cylinder | 25mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø25mm bore and 80mm stroke, M5×0.8 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA25X80H is a double-acting single-rod compact cylinder engineered with an 80 mm stroke and a 25 mm bore. It generates 245.4 N of push force and 206.2 N of pull force at 0.5 MPa. This specific SKU features an H designation, meaning it uses fluororubber (FKM) seals for enhanced thermal stability and oil resistance compared to standard NBR. The hard-anodized inner bore minimizes friction, while the integrated M5x0.8 port keeps the pneumatic footprint tight.
A short riveted assembly joins the barrel, rear cover, piston, and rod, drastically reducing axial mounting depth where a traditional round-body actuator would be too bulky. End-stop deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning operators must control the approach speed externally if operating near the maximum 500 mm/s velocity. Because this configuration lacks the S option, there is no piston magnet, so it cannot host AirTAC reed or electronic switches.

Utilizes the 80 mm stroke and FKM seals to eject plastic parts from heated molds, where elevated ambient temperatures would degrade standard rubber components.
Pushes cartons at 245.4 N push force using a short riveted body that fits neatly within tight conveyor side-frame clearances without protruding into the walkway.
Moves test tubes between processing stations with a 12.5 kg vertical lift capacity, relying on the hard-anodized bore for smooth, low-friction cycling at up to 500 mm/s.
When sizing this actuator, compare its 245.4 N push at 0.5 MPa against adjacent bores: stepping down to the SDA20 yields 157.1 N, while stepping up to the SDA32 provides 402.1 N. Based on the 245.4 N output, the safe working load is roughly 147 N (about 60 percent capacity), which translates to a vertical lift capability of approximately 12.5 kg when applying a 2:1 safety margin. Keep in mind that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only decelerates the stroke end and does not function as a locking brake. For suspended or gravity-loaded applications, install an external rod lock or a pilot-operated check valve. To order, confirm the 25 mm bore, 80 mm stroke, M5x0.8 port, female M5x0.8 rod thread, and FKM seal requirement.
Quick checklist
This 25 mm bore double-acting cylinder provides 245.4 N push and 206.2 N pull at 0.5 MPa, and 343.6 N push at 0.7 MPa. The theoretical maximum push force is 50 kgf at 1.0 MPa, with a proof pressure of 1.5 MPa.
No, this specific SKU does not include the S option, so it lacks a piston magnet and cannot trigger AirTAC reed or electronic switches. You would need the SDA25X80HS variant for position sensing capabilities.
