The AirTAC AirTAC SDA25X60BH Compact Cylinder | 25mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø25mm bore and 60mm 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 SDA25X60BH 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 merges the barrel, rear cover, piston, and rod into a highly short axial package, drastically reducing mounting depth where a conventional round-body actuator would never fit. This specific SKU features a male M8x1.25 piston rod end for direct load coupling and utilizes fluororubber (FKM) seals for enhanced thermal and oil resistance.
Because this 25 mm bore unit lacks the -S magnet code, it cannot host reed or electronic switches. End-of-travel deceleration is handled strictly by 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. Operating pressure spans 0.15-1.0 MPa, and the M5x0.8 port ensures adequate airflow for a 30-500 mm/s speed range.

Secures aluminum workpieces in a machining center using the male M8 rod thread, providing reliable 245.4 N clamping force without occupying excessive vertical tooling space.
Drives folding mechanisms on corrugated box sealing lines, where the short riveted body fits neatly within tight conveyor side frames and the FKM seals withstand lubricated environments.
Pushes molded plastic parts out of small press dies, utilizing the 60 mm stroke to clear the tooling before the next cycle begins at speeds up to 500 mm/s.
When sizing this actuator, compare its 245.4 N push at 0.5 MPa against adjacent bores: stepping down to the SDA20 yields 157.1 N, while stepping up to the SDA32 provides 402.1 N. With a safe working load around 147 N (60% of the 0.5 MPa figure) and a vertical lift capacity near 12.5 kg with a 2:1 margin, this model suits moderate pushing tasks. To finalize your order, confirm the 25 mm bore, 60 mm stroke, M5x0.8 port, male M8x1.25 rod thread, and the FKM seal option.
Keep in mind that a standard compact cylinder will not hold a load if air pressure drops or the valve is centered; the piston drifts until the bumper catches it. If your application requires strict position holding on loss of air, you must integrate an external rod lock or a pilot-operated check valve into your pneumatics circuit.
Quick checklist
This 25 mm bore 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 force is 50 kgf at 1.0 MPa, with a proof pressure rating of 1.5 MPa.
No, this specific SKU does not include a piston magnet, so reed or electronic switches cannot be used. You would need the -S variant for sensing capabilities. Additionally, end stops are managed by a fixed NBR bumper, not an adjustable air cushion, so external shock absorption is recommended for high-speed operations.
