About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X75-40B
The AirTAC SDAJ32X75-40B is a compact double-acting single-rod cylinder featuring an external M10x1.25 adjustment screw that dials the extend stop from 35 to 75 mm directly on your equipment. 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 SKU uses a male M10x1.25 piston rod thread instead of the default female M6x1.0.
The short riveted body drastically reduces axial mounting depth where a larger profile cylinder will not fit. End-of-stroke deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion. Note that this specific model lacks a piston magnet, so it cannot support reed or electronic switches without changing to an -S variant.

| Model | Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X75-40B |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Max stroke | 75 mm |
| Adjustable range | 35 – 75 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 40 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 SDAJ32X75-40B Is Used
Dial-In Forming Stops
Set the exact 35 to 75 mm extend position during stamping or forming changeovers without machining new spacers, using the 402.1 N push force to drive the tool.
Variable Height Pinning
Adjust the male M10x1.25 rod on the fly to pin parts at different heights during short-run production, relying on the fixed NBR bumper to absorb end shocks.
Prototype Clamp Tuning
Fine-tune clamping reach on prototype assemblies by turning the external screw, safely handling loads up to 20.5 kg vertically with a 2:1 safety margin.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X75-40B the Right Cylinder?
When sizing this 32 mm bore, evaluate both neighbouring options. 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 SDAJ32X75-40B hits a practical middle ground, offering a safe working load of roughly 241 N (about 60 percent of its 0.5 MPa push rating) and a vertical lift capacity near 20.5 kg with a 2:1 safety margin.
Choose this specific configuration if your fixture requires frequent changeovers or trial positioning within the 35 to 75 mm window. It features a PT1/8 port and a male M10x1.25 rod thread. Keep in mind that a plain cylinder does not hold a load if air pressure drops or the valve centres; the piston will drift. For suspended or vertical loads, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 35–75 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 SDAJ32X75-40B FAQ
At 0.5 MPa this 32 mm bore cylinder provides 402.1 N of push and 345.6 N of pull. At 0.7 MPa the push increases to 563 N and the pull to 483.8 N. The theoretical maximum push is 82 kgf at 1.0 MPa.
Turning the M10x1.25 R screw shortens the extend stroke by up to 40 mm, allowing on-machine tuning between 35 and 75 mm. This screw acts only as a mechanical stop and does not alter force. The cylinder cannot hold a load without live air pressure; use an external rod lock for load holding.
