Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X100-75B
The AirTAC Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X100-75B 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 25 to 100 mm on the machine — no shims, no part change.

About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X100-75B
The SDAJ32X100-75B is a compact double-acting single-rod cylinder featuring an external adjustable extend stop. Turning the R (M10x1.25) screw lets you dial the forward end-position anywhere between 25 and 100 mm directly on the machine, eliminating the need for shims or part swaps. Because the adjuster only 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 variant features a male M10x1.25 piston rod thread and includes no piston magnet. The short riveted body saves valuable axial mounting depth where round-body or profile cylinders will not fit. End-of-travel deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion. Operating speed ranges from 30-500 mm/s across a 0.15-1.0 MPa pressure range.

| 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 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 SDAJ32X100-75B Is Used
Tooling Changeover Stations
Dial the extend stop from 25 to 100 mm via the R screw to accommodate different part lengths during production line changeovers without swapping cylinders.
Variable Depth Flap Folding
Set precise mechanical stops for carton flaps of varying heights, relying on the 402.1 N push force to cleanly crease heavy corrugated board at 0.5 MPa.
Trial Positioning Jigs
Fine-tune the male M10x1.25 rod extension in prototyping jigs to find the exact 241 N safe working load contact point before locking the adjuster down.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X100-75B the Right Cylinder?
When sizing this 32 mm bore, evaluate your force requirements both ways. Stepping down to an SDAJ25 yields 245.4 N of push at 0.5 MPa, whereas stepping up to an SDAJ40 provides 628.3 N. The 32 mm bore offers a safe working load of roughly 241 N (about 60% of its 402.1 N capacity) and can vertically lift approximately 20.5 kg with a 2:1 safety margin. Choose this specific male-rod (-B) configuration when your tooling requires an M10x1.25 threaded attachment point.
On-machine stroke tuning is ideal for setup-heavy lines requiring frequent changeovers. Note that a plain SDAJ does not hold position or load when air is lost or the valve is centered; the piston drifts and the fixed bumper only decelerates near the end of the stroke. For load holding without live pressure, integrate an external rod lock or a pilot-operated check valve. Confirm your bore, 100 mm max stroke, 75 mm adjust window, PT1/8 port, and male rod thread before ordering.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 25–100 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 SDAJ32X100-75B 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 M10x1.25 R adjuster screw mechanically shortens the extend stroke by up to 75 mm, allowing you to set the forward stop anywhere between 25 and 100 mm. This specific SKU lacks a piston magnet, so it cannot take a magnetic switch; you would need the -S variant for reed or electronic sensing.
