Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X45-40
The AirTAC Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X45-40 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 5 to 45 mm on the machine — no shims, no part change.

About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X45-40
The AirTAC SDAJ32X45-40 is a compact double-acting single-rod cylinder featuring an external adjustable extend stop. By turning the R (M10x1.25) screw, you dial the forward end-position anywhere between 5 and 45 mm directly on the machine, eliminating the need for shims or part swaps. Retract remains full length, while the thin riveted body saves valuable axial mounting depth where larger profile cylinders cannot fit.
Because the adjuster only sets the mechanical stop and not the piston area, output force equals a standard SDA of this bore, delivering 402.1 N push at 0.5 MPa. End shock is managed solely by a fixed NBR bumper, which decelerates the stroke end but is not an adjustable air cushion. Note this specific SKU lacks a piston magnet, so it cannot host reed or electronic switches.

| Adjustable range | 5 – 45 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 SDAJ32X45-40 Is Used
Tooling Changeover
Dial the extend stop from 5 to 45 mm during fixture swaps to accommodate varying part widths without machining new spacers.
Carton Flap Folding
Fine-tune the 402.1 N push stroke on-site to fold different box profiles precisely, preventing over-travel and crushing.
Prototype Positioning
Sweep the 40 mm adjustment window to find the exact contact point for a new sensor bracket before finalizing the design.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X45-40 the Right Cylinder?
When sizing this 32 mm bore, evaluate your neighbours: stepping down to an SDAJ25 yields 245.4 N push at 0.5 MPa, whereas stepping up to an SDAJ40 provides 628.3 N push at 0.5 MPa. For the SDAJ32X45-40 itself, a safe working load is roughly 241 N (about 60% of the 0.5 MPa figure), translating to a vertical lift capacity of approximately 20.5 kg with a 2:1 safety margin.
Choose this model if your fixture requires frequent on-site stroke tuning across a 40 mm window. Remember that a plain cylinder does not hold a load when air is lost or the valve centres; the piston drifts and the fixed bumper only decelerates near the end. For secure load holding without live pressure, install an external rod lock or a pilot-operated check valve. Confirm your bore (32 mm), full stroke (45 mm), window (40 mm), port (PT1/8), and that this non-magnet variant lacks sensing capability.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 5–45 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 SDAJ32X45-40 FAQ
This 32 mm bore cylinder delivers 402.1 N push and 345.6 N pull at 0.5 MPa. At 0.7 MPa, push increases to 563 N and pull to 483.8 N. The theoretical maximum push is 82 kgf at 1.0 MPa.
The R (M10x1.25) screw mechanically limits the extend stroke, shortening it by up to 40 mm (usable range 5-45 mm). It does not alter force or lock mid-stroke; the cylinder drifts if air pressure is lost.
