The 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. 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.
