The AirTAC AirTAC SDA25X15B Compact Cylinder | 25mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø25mm bore and 15mm 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 SDA25X15B is a double-acting, single-rod compact cylinder engineered to deliver a push force of 245.4 N at 0.5 MPa. Its riveted body design integrates the barrel, rear cover, piston, and rod into a highly shortened assembly, drastically reducing axial mounting depth compared to traditional round-body units. The 25 mm bore features a hard-anodized inner wall and a two-way piston seal for reliable service.
This specific SKU includes a male-thread piston rod (M8x1.25) for secure mechanical coupling to your load. End-of-stroke deceleration is handled by a fixed NBR bumper at each end rather than an adjustable air cushion, meaning high-energy cycles may require external shock absorbers. Because this configuration lacks the -S magnet option, it cannot directly host AirTAC reed or electronic switches.

Provides the 245.4 N push force needed to actuate the cutting head plunge on an automated PCB depaneling machine, utilizing the 15 mm stroke for precise depth control.
Drives the short 15 mm folding mechanism on a continuous packaging line, where the shortened riveted body saves critical axial space within the conveyor frame.
Actuates a small back-gauge finger alignment block in a sheet metal forming station, using the male M8x1.25 rod end for rigid load coupling.
When sizing this actuator, stepping down to the SDA20 yields 157.1 N of push force at 0.5 MPa, while stepping up to the SDA32 provides 402.1 N at the same pressure. For the 245.4 N rating at 0.5 MPa, a safe working load is approximately 147 N (about 60 percent of capacity), translating to a vertical lift capability of roughly 12.5 kg with a 2:1 safety margin. To finalize your order, confirm the 25 mm bore, 15 mm stroke, M5x0.8 port, and the male M8x1.25 rod thread. Note that a standard 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. To hold a load securely without live pressure, an external rod lock or pilot-operated check valve is required.
Quick checklist
This 25 mm bore double-acting cylinder generates a push force of 245.4 N and a pull force of 206.2 N at 0.5 MPa. At 0.7 MPa, the push force is 343.6 N and the pull force is 288.6 N. The theoretical maximum push force is 50 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, with a speed range of 30-500 mm/s.
It relies on a fixed NBR bumper at each end to decelerate the piston near the stroke limits; it is not equipped with an adjustable air cushion. Additionally, it does not hold its position if air pressure is lost or the valve is centered, as the bumper is not a locking brake. An external rod lock or pilot-operated check valve is required for fail-safe load holding.
