Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X50-40B
The AirTAC Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X50-40B 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 10 to 50 mm on the machine — no shims, no part change.

About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X50-40B
The AirTAC SDAJ32X50-40B is a compact double-acting single-rod cylinder built for applications requiring exact extend positioning. A front R thread M10x1.25 adjustment screw lets you shorten the outward stroke on-site across a 10 to 50 mm window, removing the need for shims or part swaps during changeovers. Because the adjuster acts purely as a mechanical stop, output force remains identical to a standard SDA of this bore, delivering 402.1 N of push at 0.5 MPa.
This specific SKU features a male M10x1.25 piston rod thread and a 12 mm rod diameter, operating via a PT1/8 port. The short riveted body drastically reduces axial mounting depth where space is tight. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, and this base configuration lacks a piston magnet, meaning magnetic switches cannot be fitted unless you specify the -S variant.

|---|---|
| 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 SDAJ32X50-40B Is Used
Tooling Depth Calibration
Dial in the exact clamping depth on machining fixtures using the R screw, adjusting the extend stop between 10 and 50 mm without swapping cylinders.
Changeover Adjustment
Speed up product family changeovers on packaging lines by turning the M10x1.25 adjuster to set new outward positions on the fly.
Trial Positioning
Establish optimal push distances for new assembly processes, relying on the 402.1 N force output to seat components accurately.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X50-40B the Right Cylinder?
When sizing this 32 mm bore, evaluate your force requirements against its neighbours. Dropping down to an SDAJ25 yields 245.4 N of push at 0.5 MPa, whereas stepping up to an SDAJ40 provides 628.3 N. This SDAJ32X50-40B generates 402.1 N at 0.5 MPa, translating to a safe working load of roughly 241 N for a 60 percent safety margin, or a vertical lift capacity of about 20.5 kg with a 2:1 factor.
Choose this male-rod (-B) configuration if your tooling requires an externally threaded M10x1.25 attachment point. The 40 mm adjustment window is ideal for machines needing frequent trial positioning. Remember that a standard cylinder does not hold position upon air loss or valve centering; the piston drifts, and the fixed bumper only decelerates near the end. For suspended loads, integrate an external rod lock or pilot-operated check valve.

- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 10–50 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 SDAJ32X50-40B 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 it provides 563 N of push and 483.8 N of pull. The theoretical maximum push is 82 kgf at 1.0 MPa.
The R M10x1.25 screw shortens the extend stroke by up to 40 mm, allowing usable outward travel from 10 to 50 mm. This SKU includes a male M10x1.25 piston rod thread. Note that this non-S model lacks a piston magnet, so it cannot accept reed or electronic switches.
