The AirTAC AirTAC SDA25X130SH 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 SDA25X130SH 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 significantly reduces axial mounting depth compared to traditional round-body units, making it highly effective for tight machine footprints. The unit features a 10 mm piston rod, an M5x0.8 air port, and operates at speeds between 30 and 500 mm/s.
This specific configuration includes the S option for a built-in piston magnet compatible with AirTAC reed or electronic switches, and the H option for fluororubber (FKM) seals for enhanced thermal and oil resistance. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable cushion. With a 130 mm stroke, this model reaches the maximum standard stroke limit for the 25 mm bore, providing a safe working load of roughly 147 N or a vertical lift capacity of about 12.5 kg with a 2:1 safety margin.

Drives a routing blade on an electronics assembly line, utilizing the 130 mm travel and space-saving body to separate printed circuit boards within a densely packed conveyor frame.
Extends 130 mm to fold minor flaps on corrugated cartons in a continuous packaging line, where the FKM seals withstand occasional lubricant exposure from adjacent drive chains.
Actuates a lightweight entry gate on a vertical pallet lift, lifting an approximate 12.5 kg barrier with a 2:1 safety margin while fitting into the narrow 25 mm bore envelope.
When sizing this actuator, consider stepping down to the SDA20 if your layout requires less force, as it provides 157.1 N of push at 0.5 MPa. Conversely, if your application demands more power, the SDA32 offers 402.1 N at the same pressure. Keep in mind that a plain compact cylinder will drift and cannot hold a load if air pressure is lost or the valve is centered; the fixed bumper only decelerates the piston near stroke end and acts as neither a lock nor a brake. For suspended or vertical loads, an external rod lock or pilot-operated check valve is required. To order, confirm the 25 mm bore, 130 mm stroke, M5x0.8 port, male M8x1.25 rod thread, magnetic switch readiness, and FKM seal composition.
Quick checklist
At 0.5 MPa, this 25 mm bore cylinder provides 245.4 N of push force and 206.2 N of pull force. At 0.7 MPa, the push increases to 343.6 N and the pull to 288.6 N. The theoretical maximum push is 50 kgf at the maximum operating pressure of 1.0 MPa.
No, this model relies on a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion. For high-speed or high-energy applications, you should either slow down the approach speed externally or add a separate external shock absorber to prevent damage.
