The AirTAC AirTAC SDA25X100B Compact Cylinder | 25mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø25mm bore and 100mm 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 SDA25X100B is a double-acting single-rod compact cylinder engineered for tight axial spaces. It delivers 245.4 N of push force and 206.2 N of pull force at 0.5 MPa, operating at speeds between 30 and 500 mm/s. This specific SKU features a male M8x1.25 piston rod thread for direct load coupling, paired with a 10 mm rod diameter and an M5x0.8 air port.
Its riveted body construction drastically reduces overall mounting depth compared to conventional round-body units. End-stop deceleration is handled strictly by a fixed NBR bumper rather than an adjustable air cushion, meaning operators should slow the approach or utilize an external shock absorber for high-energy cycles. Note that this configuration omits the piston magnet, so position sensing is not supported here.

Pushes lightweight cardboard cartons on a logistics sorting line where the 100 mm stroke and 245.4 N output provide reliable lateral redirection without occupying excessive frame width.
Actuates the upper sealing jaw on a vertical form-fill-seal machine, utilizing the male M8x1.25 rod end for secure tool mounting and the compact body to minimize headstock height.
Ejects machined aluminum brackets from a CNC fixture, relying on the fixed NBR bumper to absorb the end-of-stroke impact within the 30-500 mm/s operational speed range.
When sizing this actuator, stepping down to the SDA20 provides 157.1 N of push at 0.5 MPa, while stepping up to the SDA32 yields 402.1 N at the same pressure. A practical safe working load is approximately 147 N (around 60 percent of the 0.5 MPa output), translating to a vertical lift capacity of roughly 12.5 kg with a 2:1 safety margin. To finalize your order, confirm the 25 mm bore, 100 mm stroke, M5x0.8 port, male M8x1.25 rod thread, and the absence of a sensor magnet.
Because this is a standard double-acting cylinder, it will not hold a load if air pressure drops or the directional valve centers. The piston will drift, and the fixed NBR bumper only decelerates the stroke near its end. If your application requires strict position holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This 25 mm bore actuator generates 245.4 N push and 206.2 N pull at 0.5 MPa, increasing to 343.6 N push and 288.6 N pull at 0.7 MPa. The theoretical maximum push is 50 kgf at 1.0 MPa, with a proof pressure of 1.5 MPa.
No, this specific SKU lacks the internal piston magnet, so it cannot trigger AirTAC reed or electronic switches. You would need the SDA25X100BS variant to utilize the sensor grooves around the body.
