Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X40-30B
The AirTAC Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X40-30B 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 10 to 40 mm on the machine — no shims, no part change.

About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X40-30B
The AirTAC SDAJ32X40-30B is a compact double-acting single-rod cylinder built for applications requiring exact extend positioning on the machine. By turning the external M10x1.25 adjuster screw, you can dial the forward stop anywhere between 10 and 40 mm without swapping shims or parts. Because the adjuster sets the mechanical stop rather than altering the piston area, output force remains identical to a standard SDA of this bore, delivering 402.1 N of push at 0.5 MPa.
This variant features a male M10x1.25 piston rod thread, a 12 mm rod diameter, and a PT1/8 air port. The short riveted body minimizes axial mounting depth where space is tight. End-of-travel deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion. Note that this specific SKU lacks a piston magnet, so it cannot support reed or electronic switches without upgrading to the -S option.

| Adjustable range | 10 – 40 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 30 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 SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X40-30B Is Used
Tooling Changeover
Dial the extend stop from 10 to 40 mm on the fly during machine setup, allowing rapid adaptation to different workpiece heights without disassembling the 32 mm bore assembly.
Flap Sealing
Fine-tune the forward contact position for varied carton depths, using the 402.1 N push force to securely fold flaps before the fixed NBR bumper absorbs the end shock.
Bending Stops
Set precise metal bending depths via the external M10x1.25 screw, leveraging the 20.5 kg vertical lift margin to position light jigs accurately during trial runs.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X40-30B the Right Cylinder?
When sizing this 32 mm bore, compare its 402.1 N push at 0.5 MPa against neighboring bores: the SDAJ25 provides 245.4 N, while the SDAJ40 yields 628.3 N. Based on the 402.1 N figure, a safe working load is roughly 241 N (about 60 percent capacity), translating to a vertical lift capability of approximately 20.5 kg with a 2:1 safety margin. Choose this male-rod (-B) model when your tooling requires an externally threaded M10x1.25 attachment point.
Engineers who frequently change tooling or need trial positioning will benefit from the 10 to 40 mm on-site adjustability. Remember that a standard cylinder does not hold position if air pressure drops or the valve is centered; the piston will drift. For load holding without live pressure, integrate an external rod lock or a pilot-operated check valve. Verify your requirements for the 32 mm bore, 40 mm maximum stroke, 30 mm window, PT1/8 port, male rod thread, and lack of magnet before ordering.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 10–40 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 SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X40-30B FAQ
This 32 mm bore double-acting cylinder provides 402.1 N push and 345.6 N pull at 0.5 MPa. At 0.7 MPa, push increases to 563 N. The theoretical maximum push force is 82 kgf at 1.0 MPa.
The external M10x1.25 screw mechanically shortens the extend stroke by up to 30 mm, giving a usable range of 10 to 40 mm. This SKU has no piston magnet, so it cannot take a switch; you must select the -S variant to use reed or electronic sensors.
