The AirTAC AirTAC SDA25X130H 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 SDA25X130H is a double-acting, single-rod compact cylinder engineered with a 25 mm bore and 130 mm stroke. It generates 245.4 N of push force and 206.2 N of pull force at 0.5 MPa. This specific SKU utilizes a fluororubber (FKM) seal, elevating its resistance to higher ambient temperatures and oil contamination compared to the standard NBR configuration.
Designed to minimize axial mounting depth, the riveted body integrates the barrel, rear cover, piston, and rod into a highly space-efficient package. The 10 mm piston rod features an M5x0.8 female thread for load coupling. Instead of an adjustable air cushion, the unit relies on a fixed NBR bumper at each end to decelerate the stroke. Because this unit lacks the -S magnet suffix, it cannot directly host AirTAC reed or electronic switches.

Suitable for high-temperature mold environments where FKM seals survive ambient heat better than standard rubber, pushing ejector pins on a 130 mm cycle.
Provides 245.4 N of extend force to actuate routing gates on packaging lines, fitting within tight conveyor side frames thanks to the compact riveted body.
Handles the opening and closing of small industrial oven doors, leveraging the fluororubber seal to maintain integrity in elevated thermal conditions.
When sizing this actuator, evaluate your force margins carefully. 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. Based on the 245.4 N output at 0.5 MPa, the computed safe working load is approximately 147 N (about 60% capacity), translating to a vertical lift capability of roughly 12.5 kg with a 2:1 safety margin. To order, confirm the 25 mm bore, 130 mm stroke, M5x0.8 port, and the female rod thread. Note that a standard cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates near the end of travel and does not function as a locking brake. For suspended loads, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This 25 mm bore double-acting cylinder provides 245.4 N push and 206.2 N pull at 0.5 MPa. At 0.7 MPa, push increases to 343.6 N and pull to 288.6 N. The theoretical maximum push force is 50 kgf at 1.0 MPa. Operating pressure spans 0.15-1.0 MPa, with a speed range of 30-500 mm/s.
No, this specific SKU lacks the internal piston magnet, so it cannot host AirTAC reed or electronic switches. You would need the -S variant for sensing capabilities. Additionally, end-stop deceleration is handled strictly by a fixed NBR bumper, which is not an adjustable air cushion.
