The AirTAC AirTAC SDA25X50SBH Compact Cylinder | 25mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø25mm bore and 50mm 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 SDA25X50SBH is a double-acting single-rod compact cylinder engineered for tight machinery footprints. Its riveted assembly significantly shortens axial mounting depth compared to round-body units, yielding a robust 245.4 N push force at 0.5 MPa. This specific configuration includes a male M8x1.25 piston rod end, a built-in magnet for position sensing, and high-temperature fluororubber (FKM) seals.
The 25 mm bore features a 10 mm rod and an M5x0.8 port, operating at speeds from 30-500 mm/s. End-stops rely on a fixed NBR bumper to decelerate the piston rather than an adjustable air cushion. Grooves around the body accept AirTAC magnetic reed or electronic switches, enabled by the integrated S-option magnet.

Ideal for routing and clamping small electronic panels in PCB assembly lines, where the short body length conserves station depth and the FKM seals resist heat from nearby soldering processes.
Provides a repeatable 245.4 N push at 0.5 MPa to seal plastic blister packs, utilizing the male M8x1.25 rod end for secure tool mounting and the magnet for cycle counting.
Actuates a routing flap on a beverage conveyor to sort containers, relying on the 50 mm stroke to swing the guide without consuming excessive frame width.
When sizing this actuator, stepping down to the SDA20 provides 157.1 N of push force at 0.5 MPa, while stepping up to the SDA32 yields 402.1 N at the same pressure. This 25 mm bore delivers a safe working load of roughly 147 N (about 60% of its 245.4 N capacity) and can vertically lift approximately 12.5 kg with a 2:1 safety margin. Ensure you specify the 50 mm stroke, M5x0.8 port, male M8x1.25 rod thread, magnet, and FKM seal when ordering.
Because a standard compact cylinder does not hold its position when air pressure is lost or the valve is centered, the piston will drift. The fixed bumper only decelerates the stroke near its end and does not act as a locking brake. If your application must maintain a load without live pressure, incorporate an external rod lock or a pilot-operated check valve.
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 increases to 343.6 N. The theoretical maximum push force is 50 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa.
No, it uses a fixed NBR bumper at each end to decelerate the stroke, which is not a field-adjustable air cushion; for high-speed cycling, you should add an external shock absorber. The SBH configuration includes a built-in piston magnet designed to trigger AirTAC reed or electronic switches mounted in the body grooves.
