The AirTAC AirTAC SDA25X10BH Compact Cylinder | 25mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø25mm bore and 10mm 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 SDA25X10BH is a double-acting single-rod compact cylinder engineered for tight axial spaces. It produces 245.4 N of push force at 0.5 MPa and uses a hard-anodized bore with a two-way piston seal. This specific SKU includes a male M8x1.25 threaded piston rod and high-temperature fluororubber (FKM) seals for enhanced oil resistance.
Its short riveted body minimizes mounting depth where standard round-body units fail to fit. End-stopping relies on a fixed NBR bumper rather than an adjustable air cushion, meaning operators should slow the approach or add external shock absorbers for high-energy cycles. Because this configuration lacks the -S magnet, it cannot host position sensing switches.

Provides the short 10 mm cutting stroke for routing printed circuit boards, where the FKM seals resist cutting fluid mist and the compact body fits inside the machine enclosure.
Drives the folding mechanism on a packaging line, using the male M8x1.25 rod end to securely attach the folding arm while saving valuable axial footprint.
Secures vials in an automated liquid handling station, where the 245.4 N push force holds parts firmly without overstressing delicate glass components.
When sizing this unit, consider stepping down to the SDA20, which yields 157.1 N of push at 0.5 MPa, or moving up to the SDA32, which provides 402.1 N at the same pressure. Based on the 245.4 N output, the safe working load is approximately 147 N (about 60 percent capacity), translating to a 12.5 kg vertical lift with a 2:1 safety margin.
Ensure your ordering essentials match the application: 25 mm bore, 10 mm stroke, M5x0.8 port, male M8x1.25 rod thread, FKM seals, and no sensor magnet. Remember that a standard compact cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates the stroke end and acts neither as a lock nor a brake. Use an external rod lock or pilot-operated check valve if the load must be held.
Quick checklist
This double-acting cylinder generates 245.4 N push and 206.2 N pull at 0.5 MPa, increasing to 343.6 N push and 288.6 N pull 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 of 30-500 mm/s.
No, this specific SKU lacks the internal piston magnet, so it cannot trigger reed or electronic switches. You would need the -S variant for sensing capabilities. Additionally, it uses a fixed NBR bumper for end deceleration rather than an adjustable air cushion, so external shock absorption is recommended for high-speed operations.
