About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X45-30B
The AirTAC SDAJ32X45-30B is a compact double-acting single-rod cylinder featuring an external adjustable extend stop. By turning the R (M10x1.25) screw, you can dial the forward end-position anywhere between 15 and 45 mm directly on your machine, eliminating the need for shims or part swaps. Because the adjuster only sets the mechanical stop and not 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 and a short riveted body that saves valuable axial mounting depth where larger profile cylinders will not fit. It uses a fixed NBR bumper at each end to decelerate the stroke, rather than an adjustable air cushion. Note that this specific SKU lacks a piston magnet, so it cannot host reed or electronic switches; choose the -S option if position sensing is required.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Max stroke | 45 mm |
| Adjustable range | 15 – 45 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 SDAJ32X45-30B Is Used
Tooling Changeover
Dial the extend stop from 15 to 45 mm via the R screw to accommodate different part heights on a machining line without machining new spacers.
Flap Folding Arms
Fine-tune the forward reach on a carton erecting station to perfectly fold varying box widths, relying on the 402.1 N push force at 0.5 MPa.
Press Fit Positioning
Set a precise mechanical lower dead point for seating bearings, using the fixed NBR bumper to absorb the end-of-stroke shock safely.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X45-30B the Right Cylinder?
When sizing this 32 mm bore, compare the thrust both ways: stepping down to an SDAJ25 yields 245.4 N of push at 0.5 MPa, while stepping up to an SDAJ40 provides 628.3 N at the same pressure. Based on the 402.1 N push figure, a safe working load is approximately 241 N (using a 60% margin), which translates to a vertical lift capacity of about 20.5 kg with a 2:1 safety factor. Choose this male-rod (M10x1.25) model if your tooling requires a threaded exterior attachment.
This unit is ideal for setups requiring frequent on-machine stroke tuning during changeovers. Remember that a plain SDAJ does not hold position or load when air is lost or the valve is centered—the fixed bumper only decelerates near the end of travel and the adjuster acts as a mechanical stop, not a lock. For load holding without live pressure, integrate an external rod lock or a pilot-operated check valve. Confirm your bore, 45 mm maximum stroke, 30 mm window, PT1/8 port, and male rod thread before ordering.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 15–45 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 SDAJ32X45-30B FAQ
This 32 mm bore cylinder features a PT1/8 air port. It generates 402.1 N of push and 345.6 N of pull at 0.5 MPa, increasing to 563 N push and 483.8 N pull at 0.7 MPa. The theoretical maximum push force is 82 kgf at 1.0 MPa.
Turning the external M10x1.25 adjuster screw shortens the extend stroke by up to 30 mm, allowing you to set the forward stop anywhere between 15 mm and 45 mm. This specific SKU does not include a piston magnet, so it cannot accept reed or electronic switches; you would need the -S variant for position sensing.
