The AirTAC AirTAC SDA25X60SH 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 SDA25X60SH is a double-acting, single-rod compact cylinder engineered with a 25 mm bore and 60 mm stroke. It delivers a push force of 245.4 N and a pull force of 206.2 N at 0.5 MPa. The short riveted body significantly reduces axial mounting depth, making it ideal for machinery where a traditional round-body unit would be too intrusive. This specific configuration includes an -S piston magnet for position sensing and an -H fluororubber (FKM) seal variant for enhanced thermal and oil resistance.
The bore inner wall is hard-anodized for longevity, and the piston relies on a two-way seal. Instead of an adjustable air cushion, the cylinder uses a fixed NBR bumper at each end to decelerate the stroke. Grooves around the body accept AirTAC magnetic reed or electronic switches, allowing precise end-of-stroke detection when paired with the internal magnet.

Actuates a short-stroke tool release mechanism in a CNC machining center, where the FKM seals resist coolant mist and the compact body fits within a tight spindle area.
Drives a 60 mm sealing head against heated platens in a packaging line, using the 245.4 N push force to close blister packs while saving vertical machine height.
Pivots a diverter arm on a conveyor sorting system, relying on the internal magnet to trigger an electronic switch for precise package routing.
When sizing this unit, evaluate stepping down to the SDA20, which yields 157.1 N of push force at 0.5 MPa, or moving up to the SDA32, which provides 402.1 N at the same pressure. For the SDA25X60SH, a practical safe working load is roughly 147 N (about 60% of the 245.4 N figure at 0.5 MPa), translating to a vertical lift capacity of approximately 12.5 kg with a 2:1 safety margin. Keep in mind that a plain compact cylinder does not hold its load if air pressure drops or the valve is centered; the piston will drift, and the fixed bumper only decelerates near the end of travel. To suspend a load safely, incorporate an external rod lock or a pilot-operated check valve.
To finalize your order, confirm the 25 mm bore, 60 mm stroke, M5x0.8 air port, built-in magnet (S), and the female M5x0.8 rod-end thread. The operating speed spans 30-500 mm/s within a 0.15-1.0 MPa pressure range.
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, push increases to 343.6 N and pull to 288.6 N. The theoretical maximum push is 50 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, with a proof pressure of 1.5 MPa, and functions in temperatures from -20 to +70 C.
It uses a fixed NBR bumper at each end to decelerate the piston; this is not an adjustable air cushion, so high-speed applications may need external shock absorbers. Because it includes the -S option, it has a built-in piston magnet designed to trigger AirTAC reed or electronic switches mounted in the body grooves.
