Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X30-30B
The AirTAC Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X30-30B 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 0 to 30 mm on the machine — no shims, no part change.

About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X30-30B
The SDAJ32X30-30B is a compact double-acting single-rod cylinder featuring an external adjustable extend stop. A male M10x1.25 piston rod comes standard on this -B variant, replacing the default female thread. By turning the R (M10x1.25) adjuster screw, you can dial the extend position from 0 to 30 mm directly on your machine without swapping parts. The retract stroke remains full length.
Because the adjuster sets the mechanical stop rather than altering the piston area, output force equals a standard SDA of this bore, delivering 402.1 N of push at 0.5 MPa. The short riveted body minimizes axial mounting depth where space is tight. End-of-travel deceleration is handled by a fixed NBR bumper, which is not an adjustable air cushion. Note this SKU lacks a piston magnet, so it cannot accept magnetic switches.

| Model | Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X30-30B |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Max stroke | 30 mm |
| Adjustable range | 0 – 30 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 SDAJ32X30-30B Is Used
Tooling Changeover
Dial the 0-30 mm extend stop during machine changeovers to accommodate different part heights without machining new spacers.
Trial Positioning
Use the M10x1.25 male rod and adjustable stop to fine-tune the extend endpoint during prototype setups until the exact 402.1 N contact point is found.
Variable Depth Flap Folding
Adjust the extend stroke on the fly for varying carton depths, letting the fixed NBR bumper absorb the end shock on each cycle.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X30-30B the Right Cylinder?
When sizing this 32 mm bore, compare it both ways: stepping down to a 25 mm bore yields 245.4 N of push at 0.5 MPa, while stepping up to a 40 mm bore provides 628.3 N. Based on the 402.1 N push figure, the safe working load is approximately 241 N (using a 60% margin), translating to a vertical lift capacity of about 20.5 kg with a 2:1 safety factor. Choose this adjustable model if your fixture requires frequent on-site stroke tuning or trial positioning. Confirm your parameters: 32 mm bore, 30 mm stroke, 30 mm adjust window, PT1/8 port, no magnet, and a male rod thread.
Keep in mind that a standard SDAJ does not hold a load if air pressure drops or the valve centers; the piston will drift. The fixed NBR bumper only decelerates the stroke near the end and the R screw is a mechanical stop, neither acts as a brake. For load holding without live pressure, integrate an external rod lock or a pilot-operated check valve into your circuit.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 0–30 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 SDAJ32X30-30B FAQ
This 32 mm bore cylinder delivers 402.1 N push and 345.6 N pull at 0.5 MPa, and 563 N push at 0.7 MPa. The theoretical maximum push force is 82 kgf at 1.0 MPa. Adjusting the stroke does not alter these force values.
The R (M10x1.25) screw mechanically shortens the extend stroke by up to 30 mm, giving a usable extend range of 0-30 mm while retract remains full. This specific SKU has no piston magnet, so it cannot accept reed or electronic switches; you would need the -S variant for sensing.
