Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X90-75B
The AirTAC Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X90-75B 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 15 to 90 mm on the machine — no shims, no part change.

About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X90-75B
The AirTAC SDAJ32X90-75B is a compact double-acting single-rod cylinder featuring an external extend stop. An M10x1.25 adjuster screw lets you dial the outward travel down from the 90 mm maximum to as little as 15 mm directly at the machine, eliminating shims or part swaps. Because the mechanism limits travel rather than altering piston area, output remains identical to a standard 32 mm bore SDA, yielding 402.1 N of push force at 0.5 MPa.
This variant uses a male M10x1.25 piston rod thread and a PT1/8 air port. Its short riveted body conserves axial mounting depth where space is tight. End-of-stroke deceleration is handled by a fixed NBR bumper, which is not an adjustable air cushion. Note that this specific SKU lacks a piston magnet, so it cannot host reed or electronic switches without changing to an -S version.

|---|---|
| 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 75 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 SDAJ32X90-75B Is Used
Short-Stroke Clamping
Dial the extend stop down to 15 mm for clamping fragile castings, ensuring the 402.1 N push force makes contact without over-traveling.
Rapid Format Changeover
Turn the M10x1.25 adjuster to shift the extend position between product runs, saving setup time without swapping the cylinder body.
Trial Positioning
Fine-tune the outward reach during initial fixture commissioning to find the exact 15 to 90 mm engagement point before locking the screw.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X90-75B the Right Cylinder?
When sizing this 32 mm bore actuator, verify your force requirements against its neighbours. Dropping down to an SDAJ25 provides 245.4 N of push at 0.5 MPa, while stepping up to an SDAJ40 yields 628.3 N at the same pressure. The 32 mm bore offers a calculated safe working load of roughly 241 N, or about 60 percent of its 402.1 N capacity, and can vertically lift approximately 20.5 kg with a 2:1 safety margin.
Choose this -75B configuration if your fixture requires a male M10x1.25 rod end and frequent on-site stroke tuning across the 15 to 90 mm window. Remember that the fixed NBR bumper only decelerates the impact near the end of travel; it is not a brake. If your application must hold a vertical load during air loss or valve centering, add an external rod lock or pilot-operated check valve, as the adjuster screw acts purely as a mechanical stop and will not prevent drift.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 15–90 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 SDAJ32X90-75B FAQ
At 0.5 MPa this 32 mm bore cylinder provides 402.1 N push and 345.6 N pull. At 0.7 MPa it delivers 563 N push and 483.8 N pull. The theoretical maximum output is 82 kgf at 1.0 MPa.
Turning the R (M10x1.25) screw mechanically limits the extend stroke, shortening it by up to 75 mm from the 90 mm maximum down to 15 mm. The retract stroke remains full, and the mechanism does not alter the output force.
