Airtac B01-SDAJ Special Cylinder B01-SDAJ32X20-20B
The AirTAC Airtac B01-SDAJ Special Cylinder B01-SDAJ32X20-20B is a genuine double-acting COMPACT cylinder (Ø32mm bore) whose extend end-position is set by an external M10×1.25 adjustment screw. You can dial the stroke anywhere from 0 to 20 mm on the machine — no shims, no part change.

About the Airtac B01-SDAJ Special Cylinder B01-SDAJ32X20-20B
The B01-SDAJ32X20-20B is a double-acting compact cylinder where the leading B01- prefix denotes AirTAC's application-dedicated (customer-specified) line; mechanically, it is identical to the base SDAJ32X20-20B. It features a 32 mm bore and a male M10x1.25 piston rod. An external R (M10x1.25) adjuster screw lets you dial the extend stop directly on the machine, shortening the forward stroke by up to 20 mm for a usable extend range of 0-20 mm. Retract remains full length.
Because the adjuster sets the mechanical stop rather than the piston area, output force equals a standard SDA of this bore, delivering about 402.1 N push at 0.5 MPa. The short riveted body saves axial mounting depth where round-body or profile cylinders will not fit. End shock is handled by a fixed NBR bumper that decelerates the stroke, which is not an adjustable air cushion. This SKU lacks a piston magnet, so it cannot host reed or electronic switches; the -S variant is required for sensing.

| Model | Airtac B01-SDAJ Special Cylinder B01-SDAJ32X20-20B |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Max stroke | 20 mm |
| Adjustable range | 0 – 20 mm |
| Adjuster thread (R) | M10×1.25 |
| Port size | PT1/8 |
| Acting type | Double acting |
|---|---|
| Rod end thread | M6×1.0 F / M10×1.25 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 20 mm. Force is unchanged from a standard SDA of the same bore. Specifications follow the official AirTAC SDAJ datasheet.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 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.

Where the Airtac B01-SDAJ Special Cylinder B01-SDAJ32X20-20B Is Used
Trial Positioning Jigs
Dial the extend stop from 0 to 20 mm during prototype runs to find the exact clamping contact point without machining new spacers.
Changeover Tooling
Rapidly reconfigure the forward stroke on packaging lines for different carton depths using the M10x1.25 adjuster screw.
Short-Depth Ejectors
Fit the compact riveted body into tight machine frames to push parts with 402.1 N of force where axial length is restricted.
Is the Airtac B01-SDAJ Special Cylinder B01-SDAJ32X20-20B the Right Cylinder?
When sizing this 32 mm bore, look both ways: stepping down to SDAJ25 yields 245.4 N push at 0.5 MPa, while stepping up to SDAJ40 provides 628.3 N. This model delivers 402.1 N push at 0.5 MPa, translating to a safe working load of roughly 241 N (about 60 percent of capacity) and a vertical lift capability of approximately 20.5 kg with a 2:1 margin.
Confirm the 32 mm bore, 20 mm stroke, 20 mm adjust window, PT1/8 port, male M10x1.25 rod thread, and no magnet. It is ideal for setups needing frequent on-site stroke tuning. Remember that a plain cylinder does not hold its load on air loss or valve centring; the piston drifts and the bumper only decelerates near the end. For a held load without live pressure, specify an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 0–20 mm
- ✓ Force at your working pressure
- ✓ Access to reach the R adjuster
- ✓ Magnet (S) for sensors?
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Lock the M10×1.25 adjuster after setting the stroke.
- check Avoid side load on the piston rod.
- check Front/rear covers are riveted — do not dismantle.
- check Installation by qualified personnel per AirTAC docs.
Airtac B01-SDAJ Special Cylinder B01-SDAJ32X20-20B FAQ
At 0.5 MPa it provides 402.1 N push and 345.6 N pull; at 0.7 MPa it provides 563 N push and 483.8 N pull. The theoretical maximum is 82 kgf at 1.0 MPa. It operates at 30-500 mm/s, uses a PT1/8 port, and the B01- prefix indicates an application-dedicated variant mechanically identical to the SDAJ32X20-20B.
Turning the R (M10x1.25) screw shortens the forward stroke by up to 20 mm, giving a usable extend range of 0-20 mm; retract is always full. The screw acts only as a mechanical stop and does not alter force. The fixed NBR bumper decelerates the end of travel but does not lock the piston, so an external rod lock or pilot-operated check valve is required to hold a load without air pressure.
