Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X65-40B
The AirTAC Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X65-40B 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 25 to 65 mm on the machine — no shims, no part change.

About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X65-40B
The AirTAC SDAJ32X65-40B is a compact double-acting single-rod cylinder featuring an external extend stop. A front R (M10x1.25) screw lets you dial the forward end-position between 25 and 65 mm directly on the machine. Because the adjuster sets the mechanical stop rather than 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 specific SKU includes a male-thread M10x1.25 piston rod for direct tooling attachment and lacks a piston magnet, meaning it cannot host reed or electronic switches. The short riveted body minimizes axial mounting depth where space is tight. End-of-travel deceleration is handled by 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 | 65 mm |
| Adjustable range | 25 – 65 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 SDAJ32X65-40B Is Used
Trial Positioning Jigs
Dial the extend stop across the 25-65 mm window to find the exact contact point for prototype parts before locking the tooling down.
Rapid Format Changeover
Turn the M10x1.25 adjuster to shift the male rod endpoint instantly when switching packaging lines between different carton depths.
Multi-Depth Ejection
Set the mechanical stop to push varied product lengths from a single station without swapping out the entire actuator body.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X65-40B the Right Cylinder?
When sizing this 32 mm bore, evaluate your neighbors: stepping down to an SDAJ25 yields 245.4 N push at 0.5 MPa, while stepping up to an SDAJ40 provides 628.3 N. Based on the 402.1 N rating, a safe working load is roughly 241 N (about 60 percent of capacity), translating to a vertical lift of approximately 20.5 kg with a 2:1 safety margin. Choose this unit when you need on-site stroke tuning during frequent changeovers.
This configuration specifies a 65 mm maximum stroke, a 40 mm adjustment window, a PT1/8 port, no magnet, and a male M10x1.25 rod thread. Remember that a plain cylinder does not hold position on air loss or valve centering; the piston drifts. For load holding without live pressure, install an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 25–65 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 SDAJ32X65-40B 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 is 82 kgf at 1.0 MPa.
Turning the external R (M10x1.25) screw shortens the extend stroke by up to 40 mm, giving a usable forward range of 25 to 65 mm. The retract stroke remains full. Note that this SKU lacks the -S magnet, so it cannot support position sensing.
