The AirTAC AirTAC SDA25X35BH Compact Cylinder | 25mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø25mm bore and 35mm 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 SDA25X35BH is a double-acting single-rod compact cylinder engineered for tight axial spaces. It delivers a push force of 245.4 N and a pull force of 206.2 N at 0.5 MPa. The riveted unibody construction merges the barrel and covers to minimize mounting depth, offering a footprint advantage over conventional round-body actuators. This specific SKU includes an FKM fluororubber seal for enhanced thermal and oil resistance.
This model features a 10 mm piston rod with a male M8x1.25 thread end for direct load coupling. Instead of an adjustable air cushion, the piston strikes a fixed NBR bumper at each stroke terminus to absorb impact. Because this configuration lacks the -S magnet, it cannot host position sensing switches.

Provides the precise 35 mm linear push to separate routed circuit boards, utilizing the FKM seals to withstand localized heat and solder flux residues.
Applies 245.4 N of clamping force at 0.5 MPa to close sealing dies, with the male M8x1.25 rod threading directly into the upper tooling plate.
Actuates a short diverter arm to route small packages on a conveyor line, where the compact riveted body saves valuable space along the machine frame.
When sizing your application, consider stepping down to the SDA20 which yields 157.1 N push at 0.5 MPa, or moving up to the SDA32 which provides 402.1 N push at 0.5 MPa. The 245.4 N output at 0.5 MPa translates to a safe working load around 147 N, or a vertical lift capacity near 12.5 kg with a 2:1 safety margin. To finalize your order, confirm the 25 mm bore, 35 mm stroke, M5x0.8 port, male M8 rod thread, and FKM seal. Remember that a standard actuator will drift and cannot hold a load if air pressure drops; utilize an external rod lock or pilot-operated check valve if position holding is mandatory.
Quick checklist
This 25 mm bore double-acting cylinder generates 245.4 N push and 206.2 N pull at 0.5 MPa, 343.6 N push and 288.6 N pull at 0.7 MPa, with a theoretical maximum push of 50 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, and the operational speed spans 30-500 mm/s.
No. This model relies strictly on fixed NBR bumpers to decelerate the stroke end and lacks an adjustable air cushion. Additionally, because it is configured without the -S piston magnet, it cannot support reed or electronic switches; you must select the -S variant to enable position sensing.
