The AirTAC AirTAC SDA25X130B 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 SDA25X130B is a double-acting, single-rod compact cylinder engineered to deliver 245.4 N of push force and 206.2 N of pull force at 0.5 MPa. Its riveted assembly merges the barrel, rear cover, piston, and rod into a remarkably short axial footprint, saving valuable machine space where a conventional round-body unit would be too deep. The internal bore is hard-anodized and utilizes a two-way piston seal for consistent low-friction motion across the 30-500 mm/s speed range.
This specific configuration features a 130 mm stroke and a male M8x1.25 threaded piston rod end, providing a robust mechanical coupling for your load. Because this SKU lacks the -S magnet option, it cannot host AirTAC reed or electronic switches. End-of-travel deceleration is handled strictly by fixed NBR bumpers rather than adjustable air cushions, meaning high-energy cycles may require an external shock absorber to prevent impact wear.

Actuates a routing flap on a logistics sorting line, utilizing the 130 mm stroke to redirect parcels weighing up to 12.5 kg into secondary chutes.
Drives a mechanical arm to tuck minor flaps on a case erector, where the male M8x1.25 rod end secures the custom folding bracket against side load.
Adjusts the position of a yarn guide bar to maintain material tension, benefiting from the short riveted body to fit within the dense loom framework.
When sizing this actuator, stepping down to the SDA20 reduces the 0.5 MPa push output to 157.1 N, while stepping up to the SDA32 increases it to 402.1 N. At 245.4 N, this 25 mm bore yields a safe working load of roughly 147 N (about 60% of the 0.5 MPa figure), which translates to a vertical lift capacity near 12.5 kg when applying a 2:1 safety margin. Ensure your ordering essentials match this SKU: 25 mm bore, 130 mm stroke, M5x0.8 air port, male M8x1.25 rod thread, and no sensor magnet.
Keep in mind that a standard double-acting cylinder like this does not inherently hold its position if air pressure drops or the directional valve is centered. The piston will drift under load, and the fixed NBR bumpers only decelerate the stroke near the end caps—they do not function as a locking brake. If your application demands fail-safe load holding, you must integrate an external rod lock or a pilot-operated check valve into the pneumatic circuit.
Quick checklist
This 25 mm bore double-acting cylinder provides 245.4 N push and 206.2 N pull at 0.5 MPa, and 343.6 N push at 0.7 MPa. The theoretical maximum push force is 50 kgf at 1.0 MPa. It operates on filtered air between 0.15 and 1.0 MPa, with a proof pressure of 1.5 MPa, and supports speeds from 30 to 500 mm/s.
No. This SKU lacks the -S magnet, so it cannot accept AirTAC reed or electronic switches. Additionally, it uses fixed NBR bumpers at both ends to absorb end-of-stroke impact rather than field-adjustable air cushions. For high-speed cycling, you should add an external shock absorber or slow the approach speed.
