The AirTAC AirTAC SDA25X130SB Compact Cylinder | 25mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø25mm bore and 130mm 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 SDA25X130SB is a double-acting, single-rod compact cylinder engineered to deliver a 245.4 N push force at 0.5 MPa. Built with a hard-anodized bore and a two-way piston seal, its riveted body design drastically reduces axial mounting depth compared to conventional round-body units, saving valuable machine footprint. This specific configuration includes a built-in piston magnet (-S) for position sensing and a male-thread piston rod (-B).
Because the 130 mm stroke exceeds the standard 120 mm limit for this 25 mm bore, it is manufactured as a non-standard, made-to-order unit. It operates at speeds between 30-500 mm/s and relies on a fixed NBR bumper at each end to decelerate the stroke end. Note that this fixed bumper is not an adjustable air cushion; for high-energy cycles, you should slow the approach or add an external shock absorber.

Pushes lightweight cardboard cartons on a logistics sorting line where the 245.4 N force and 130 mm travel provide ample reach without excessive bulk.
Secures delicate printed circuit boards during assembly, utilizing the male M8x1.25 rod end for secure tooling attachment and the -S magnet for stroke confirmation.
Maintains web tension on a packaging machine, using the compact riveted body to fit within tight frame clearances where a standard profile cylinder would fail.
When sizing this unit, consider stepping down to the SDA20 which provides 157.1 N of push at 0.5 MPa, or stepping up to the SDA32 which yields 402.1 N at the same pressure. Based on the 245.4 N output, the safe working load is approximately 147 N (about 60 percent of capacity), translating to a vertical lift of roughly 12.5 kg with a 2:1 safety margin. Keep in mind a plain SDA does not hold its load if air pressure is lost or the valve is centered—the piston will drift, and the fixed bumper only decelerates near the stroke end, so an external rod lock or pilot-operated check valve is required for holding. To order, confirm the 25 mm bore, 130 mm non-standard stroke, M5x0.8 port, built-in magnet (S), and male M8x1.25 rod thread (B).
Quick checklist
The SDA25X130SB 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 is 343.6 N and pull is 288.6 N. The theoretical maximum push 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. If air is lost or the valve is centered, the cylinder cannot hold its load and will drift—an external rod lock or pilot-operated check valve is needed for position holding.
