The AirTAC AirTAC SDA25X65B Compact Cylinder | 25mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø25mm bore and 65mm 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 SDA25X65B is a double-acting, single-rod compact cylinder engineered with a short riveted body to minimize axial footprint in tight machinery. Operating at 0.5 MPa, it generates 245.4 N of push force and 206.2 N of pull force. This specific configuration includes a male M8x1.25 threaded piston rod for secure mechanical load coupling.
This model features a 10 mm piston rod and an M5x0.8 air port. The bore is hard-anodized for longevity, and end-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable cushion. Because this SKU lacks the -S magnet option, it cannot directly host AirTAC reed or electronic switches.

Drives the short folding arm on a packaging line to tuck corrugated flaps, utilizing the 65 mm stroke and male M8x1.25 rod end to push mechanically without excessive axial depth.
Actuates a routing flap on a conveyor sorting system where the 245.4 N push force at 0.5 MPa easily overcomes the friction of lightweight parcels.
Lowers an electronic test probe onto a printed circuit board fixture, applying a controlled 147 N safe working load to verify connections without damaging the substrate.
When sizing this actuator, evaluate your force margins carefully. If you need less thrust, stepping down to the SDA20 provides 157.1 N of push at 0.5 MPa; if your application demands more power, stepping up to the SDA32 yields 402.1 N at the same pressure. For the SDA25X65B, a practical safe working load is roughly 147 N (about 60% of the 245.4 N figure), translating to a vertical lift capacity of approximately 12.5 kg with a 2:1 safety margin.
Confirm your ordering essentials: 25 mm bore, 65 mm stroke, M5x0.8 port, male M8x1.25 rod thread, and no sensor magnet. Note that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only decelerates the stroke end without locking the piston. To suspend a load safely without live pressure, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This 25 mm bore cylinder delivers 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 is 50 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, handles a proof pressure of 1.5 MPa, and runs at speeds from 30-500 mm/s.
No adjustable air cushion is available; end stops rely on a fixed NBR bumper, so you should slow the approach or add an external shock absorber for high-energy loads. Additionally, this specific SKU lacks the -S magnet, meaning it cannot support reed or electronic switches without changing to the -S variant.
