The AirTAC AirTAC SDA25X10SH Compact Cylinder | 25mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø25mm bore and 10mm 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 SDA25X10SH is a double-acting single-rod compact cylinder engineered for minimal axial footprint machinery. It delivers a push force of 245.4 N and a pull force of 206.2 N at 0.5 MPa. Built with a hard-anodized bore and a two-way piston seal, the riveted body design drastically reduces mounting depth compared to round-body units.
This specific configuration includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves. The -H designation equips the unit with fluororubber (FKM) seals for enhanced thermal and oil resistance. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable cushion, and the 10 mm stroke operates on an M5x0.8 port.

Ideal for electronics assembly lines where the 10 mm stroke precisely shifts printed circuit boards, utilizing the 245.4 N push force without consuming valuable conveyor width.
Drives short-stroke sealing jaws on vertical form-fill-seal equipment, where the FKM seals withstand higher thermal exposure from heat bars and ambient packaging environments.
Ejects small stamped metal parts from progressive dies, using the 12.5 kg vertical lift capacity to positively clear the tooling before the next press cycle.
When sizing this 25 mm bore actuator, evaluate your force margins both ways: stepping down to the SDA20 yields 157.1 N of push at 0.5 MPa, while stepping up to the SDA32 provides 402.1 N. For the SDA25X10SH, a safe working load is approximately 147 N (about 60% of its 245.4 N capacity), translating to a vertical lift capability of roughly 12.5 kg with a 2:1 safety margin. To finalize your order, confirm the 10 mm stroke, M5x0.8 port, female M5x0.8 rod thread, the -S magnet, and the -H FKM seal option.
Keep in mind that a standard compact cylinder does not hold its position if air pressure drops or the valve is centered. The piston will drift, as the fixed NBR bumper only decelerates the stroke near its end and acts purely as an end-stop, never as a locking brake. If your application requires absolute load holding on air loss, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This 25 mm bore double-acting cylinder provides a push force of 245.4 N and a pull force of 206.2 N at 0.5 MPa. At 0.7 MPa, push increases to 343.6 N and pull to 288.6 N. The theoretical maximum push is 50 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, with a proof pressure of 1.5 MPa, and the speed range is 30-500 mm/s.
No, the SDA series uses a fixed NBR bumper at each end to decelerate the stroke, not a field-adjustable air cushion. For high-speed or high-energy cycles, you should add an external shock absorber or slow the approach speed. Additionally, the bumper is not a locking device; the piston will drift on air loss, so an external rod lock or pilot-operated check valve is required for load holding.
