The AirTAC Airtac B01-SDAJ Special Cylinder B01-SDAJ25X10-10B is a genuine double-acting COMPACT cylinder (Ø25mm bore) whose extend end-position is set by an external M8×1.25 adjustment screw. You can dial the stroke anywhere from 0 to 10 mm on the machine — no shims, no part change.
The B01-SDAJ25X10-10B is an AirTAC compact double-acting cylinder with an external adjustable extend stop. The B01- prefix marks this as an application-dedicated, customer-specified variant of the base SDAJ25X10-10B, meaning it is mechanically identical to the standard model but grouped for specific build requirements. It features a 25mm bore and a 10mm stroke.
An M8x1.25 adjuster screw lets you dial the extend end-position on the machine between 0 and 10mm without changing parts. The short riveted body saves axial mounting depth where round-body or profile cylinders will not fit. Force equals a standard SDA of this bore, delivering about 245.4 N push at 0.5 MPa, and end shock is handled by a fixed NBR bumper rather than an adjustable air cushion.

| Adjustable range | 0 – 10 mm |
| Adjuster thread (R) | M8×1.25 |
| Port size | M5×0.8 |
| Acting type | Double acting |
|---|---|
| Rod end thread | M5×0.8 F / M8×1.25 male (B) |
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 500 mm/s |
| Cushion | Fixed NBR bumper (both ends) |
The adjustment screw shortens the extend stroke by up to 10 mm. Force is unchanged from a standard SDA of the same bore. Specifications follow the official AirTAC SDAJ datasheet.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 245 N | 206 N |
| 0.7 MPa | 344 N | — |
| Max (@1.0 MPa) | 50 kgf | |
Force matches a standard SDA of the same bore; the adjuster only sets the stop position, not the area. Actual usable force is lower than theoretical due to friction.

Dial the extend stop from 0 to 10mm to find the exact contact point during prototype tooling setup without machining new spacers.
Fine-tune the stroke on a package routing gate to accommodate different carton sizes on the fly using the 245.4 N push force.
Secure delicate workpieces with a male M8x1.25 rod, adjusting the final 10mm extension to prevent over-travel damage.
Sizing this 25mm bore involves looking both ways: stepping down to SDAJ20 yields 157.1 N push at 0.5 MPa, while stepping up to SDAJ32 provides 402.1 N. With a safe working load around 147 N (60% of the 245.4 N figure) and a vertical lift capacity of roughly 12.5 kg with a 2:1 margin, this unit suits moderate actuation. It is ideal for setups requiring on-site stroke tuning. Confirm the 25mm bore, 10mm stroke, 10mm window, M5x0.8 port, male M8x1.25 rod thread, and lack of a magnet.
Remember that a plain cylinder does not hold its load on air loss or when the valve is centred; the piston drifts and the fixed bumper only decelerates near the stroke end. For a held load without live pressure, use an external rod lock or a pilot-operated check valve.
Quick checklist
The double-acting single rod provides 245.4 N push and 206.2 N pull at 0.5 MPa, 343.6 N push and 288.6 N pull at 0.7 MPa, with a theoretical maximum of 50 kgf at 1.0 MPa.
The B01- prefix denotes an application-dedicated customer-specified variant of the SDAJ25X10-10B, sharing identical specs. The M8x1.25 R screw shortens the extend stop by up to 10mm (usable 0-10mm); it sets the stop position and does not change force or lock mid-stroke.
