The AirTAC AirTAC SDA25X30SB Compact Cylinder | 25mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø25mm bore and 30mm 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 SDA25X30SB is a double-acting, single-rod compact cylinder engineered to deliver a push force of 245.4 N and a pull force of 206.2 N at 0.5 MPa. Its riveted body assembly significantly reduces axial mounting depth, making it highly effective for machinery where a standard round-body unit would simply be too long. The 25 mm bore features a hard-anodized inner wall and operates at speeds between 30 and 500 mm/s.
This specific configuration includes an integrated piston magnet (-S) for position sensing using an AirTAC reed or electronic switch fitted into the body grooves. It also features a male-thread piston rod (-B) sized at M8x1.25 for secure mechanical load coupling. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning high-energy cycles may require an external shock absorber.

Actuates a short stroke gate to route printed circuit boards into the drilling station, utilizing the 245.4 N push force and compact 30 mm stroke to fit within dense electronics manufacturing equipment.
Drives a mechanical folder arm to tuck minor flaps on packaging lines, where the male M8x1.25 rod end secures the linkage and the fixed NBR bumper absorbs the repetitive end-stop impact.
Moves a fluid nozzle into exact position over vials, relying on the piston magnet and an electronic switch to confirm the 30 mm extension before a timed chemical release.
When sizing this unit, consider stepping down to the SDA20, which provides 157.1 N of push force at 0.5 MPa, or stepping up to the SDA32, which yields 402.1 N at the same pressure. The 25 mm bore offers a computed 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. To finalize your order, confirm the 30 mm stroke, M5x0.8 port, built-in magnet, and the male M8x1.25 rod thread. Note that a plain compact cylinder will drift and cannot hold a load if air pressure is lost or the valve is centered; maintaining a vertical load requires an external rod lock or a pilot-operated check valve.
Quick checklist
At 0.5 MPa, the push force is 245.4 N and the pull force is 206.2 N. 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 the maximum operating pressure of 1.0 MPa.
It uses a fixed NBR bumper at each end to decelerate the piston near the stroke limits; it is not an adjustable air cushion. Additionally, the cylinder cannot hold a load if air is lost or the valve is centered—the piston will drift, so an external rod lock or pilot-operated check valve is required for position holding.
