About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X45-30
The AirTAC SDAJ32X45-30 is a double-acting compact cylinder featuring an external M10x1.25 adjuster screw that dials the extend stop directly on your machine. You can set the outward travel anywhere between 15 and 45 mm without swapping shims or parts, while the retract motion remains full length.
Because the mechanism limits the stop rather than altering the piston area, output force matches a standard SDA of this size, delivering 402.1 N of push at 0.5 MPa. The short riveted body minimizes axial mounting depth where space is tight. End-of-stroke deceleration relies on a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion.

|---|---|
| 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 SDAJ32X45-30 Is Used
Tooling Changeover
Dial the extend stop from 15 to 45 mm on the fly to accommodate varying jig heights during production line changeovers.
Trial Positioning
Perfect for prototype assembly stations where the exact 402.1 N push contact point must be fine-tuned without disassembling the fixture.
Vertical Lift Stops
Set precise upper travel limits for 20.5 kg vertical lifts, relying on the mechanical stop rather than ambiguous air pressure.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X45-30 the Right Cylinder?
When sizing this 32 mm bore, stepping down to an SDAJ25 yields 245.4 N of push at 0.5 MPa, whereas moving up to an SDAJ40 provides 628.3 N. This SDAJ32X45-30 strikes a middle ground, offering a safe working load around 241 N (roughly 60 percent of its 0.5 MPa rating) and a vertical lift capacity near 20.5 kg with a 2:1 safety margin.
It is ideal for setups requiring frequent on-site stroke tuning during commissioning. Remember that the fixed bumper only decelerates the stroke end; a plain cylinder cannot hold a load if air pressure drops or the valve centers. For secure load holding without live pressure, install an external rod lock or a pilot-operated check valve. This specific SKU lacks a piston magnet, so it cannot accept magnetic switches (order the -S variant for sensing). It features a PT1/8 port and a female M6x1.0 rod-end thread.
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 SDAJ32X45-30 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 push is 82 kgf at 1.0 MPa.
Turning the R (M10x1.25) screw shortens the extend stroke by up to 30 mm, allowing you to set the outward stop anywhere between 15 and 45 mm. The retract stroke remains full length.
