The AirTAC AirTAC SDA25X30B Compact Cylinder | 25mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø25mm bore and 30mm 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 SDA25X30B 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 significantly reduces axial mounting depth compared to conventional round-body units, making it highly effective for tight machine footprints. The unit operates at speeds between 30-500 mm/s and features a hard-anodized bore with a two-way piston seal.
This specific SKU includes the B option, providing a male M8x1.25 threaded piston rod end for straightforward load coupling. Because it lacks the S suffix, there is no piston magnet, meaning it cannot host reed or electronic switches. End-stop deceleration relies strictly on a fixed NBR bumper, which is not an adjustable air cushion, so high-energy cycles may require external shock absorption.

Actuates the cutting head feed on an electronics depaneling machine, where the short 30 mm stroke and 245.4 N push force cleanly separate routed circuit boards.
Folds minor carton flaps on a continuous packaging line, utilizing the male M8x1.25 rod end to securely mount a folding blade within a narrow conveyor frame.
Ejects small metal pins from a progressive stamping die, relying on the fixed NBR bumper to absorb the end-stop impact without requiring extensive axial depth.
When sizing this 25 mm bore, compare its 245.4 N push at 0.5 MPa against adjacent options: 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), translating to a vertical lift capacity near 12.5 kg with a 2:1 safety margin. Keep in mind this compact body suits short strokes; for long reaches, a guided cylinder is preferable.
To finalize your order, confirm the 25 mm bore, 30 mm stroke, and M5x0.8 port. This SDA25X30B configuration specifies a male M8x1.25 rod thread and no sensor magnet. Note that a plain double-acting cylinder drifts when air pressure is lost or the valve is centered—the fixed bumper only decelerates near the stroke end and acts as neither a lock nor a brake. To suspend a load safely without live pressure, install an external rod lock or a pilot-operated check valve.
Quick checklist
This double-acting 25 mm bore cylinder generates 245.4 N push and 206.2 N pull at 0.5 MPa, and 343.6 N push at 0.7 MPa. Its theoretical maximum push force is 50 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa.
No, this specific SKU lacks the S suffix, meaning it has no internal piston magnet and cannot trigger reed or electronic switches. Additionally, end-stop deceleration is handled by a fixed NBR bumper, which is not a field-adjustable air cushion.
