The AirTAC AirTAC SDA25X100 Compact Cylinder | 25mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø25mm bore and 100mm 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 SDA25X100 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 joins the barrel, rear cover, piston, and rod into a highly shortened unit, drastically reducing axial mounting depth compared to conventional round-body designs. The 25 mm bore features a hard-anodized inner wall and a two-way piston seal for reliable friction-free motion.
This specific configuration provides a 100 mm stroke, utilizing a 10 mm piston rod and an M5x0.8 air port. End-of-travel deceleration is handled strictly by a fixed NBR bumper at each end rather than an adjustable air cushion. Because this SKU lacks the S option, it has no piston magnet and cannot support magnetic switches.

Actuates a routing flap on a logistics sorting line, using the 100 mm stroke to redirect parcels efficiently within a tight conveyor frame footprint.
Drives a mechanical arm to fold corrugated box flaps prior to tape sealing, benefiting from the short body length to fit between adjacent packaging modules.
Pushes processed test tubes out of a centrifuge carousel, where the 245.4 N extension force easily overcomes light friction without stressing delicate components.
When sizing this unit, 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. A practical safe working load is roughly 147 N (about 60% of the 0.5 MPa figure), allowing a vertical lift of approximately 12.5 kg with a 2:1 safety margin. To finalize your order, confirm the 25 mm bore, 100 mm stroke, M5x0.8 port, female rod-end thread, and the absence of a sensor magnet.
Keep in mind that a standard compact cylinder cannot hold a load if air pressure drops or the valve is centered. The piston will drift, and the fixed NBR bumper only decelerates the stroke near its end without acting as a mechanical lock. If your application demands position holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This double-acting cylinder provides 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 force 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 supports a speed range of 30-500 mm/s.
No, this SKU lacks the S option, meaning it has no internal piston magnet and cannot use reed or electronic switches. Additionally, it uses a fixed NBR bumper at each end to decelerate the stroke. It is not an adjustable air cushion, so for high-speed operations you should add an external shock absorber or slow the approach.
