Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X35-40B
The AirTAC Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X35-40B 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 0 to 35 mm on the machine — no shims, no part change.

About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X35-40B
The AirTAC SDAJ32X35-40B is a compact double-acting single-rod cylinder featuring an external extend stop. By turning the R (M10x1.25) adjuster screw, you shorten the forward stroke by up to 40 mm directly on the machine, yielding a usable extend range of 0 to 35 mm without swapping parts. Because the screw sets the mechanical stop rather than altering the piston area, output force equals a standard SDA of this bore, delivering 402.1 N of push at 0.5 MPa.
Its short riveted body saves axial mounting depth where round-body or profile cylinders will not fit. The unit uses a fixed NBR bumper at each end to decelerate the stroke end; this is not an adjustable air cushion, nor does it act as a mid-stroke lock. This specific SKU includes a male M10x1.25 piston rod and lacks a piston magnet, meaning it cannot host reed or electronic switches without upgrading to the -S variant.

| 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 SDAJ32X35-40B Is Used
Tooling Changeover
Dial the extend stop from 0 to 35 mm during die swaps to accommodate varying part thicknesses without machining new spacers.
Flap Sealing
Fine-tune the 402.1 N push stroke on-site to press carton flats securely, preventing crushing while ensuring a positive seal.
Prototype Positioning
Sweep the mechanical stop through its range to find the exact contact point for a new sensor bracket before locking the R screw down.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X35-40B the Right Cylinder?
When sizing this 32 mm bore, evaluate both neighbours: stepping down to the SDAJ25 yields 245.4 N of push at 0.5 MPa, while stepping up to the SDAJ40 provides 628.3 N. The SDAJ32X35-40B itself provides 402.1 N at 0.5 MPa, translating to a safe working load of roughly 241 N or a vertical lift of about 20.5 kg with a 2:1 margin. Choose this model when your fixture requires on-site stroke tuning during commissioning.
Confirm the 32 mm bore, 35 mm maximum stroke, and 40 mm adjust window suit your motion envelope. This unit features a PT1/8 port and a male M10x1.25 rod thread. Note that a plain cylinder does not hold its load on air loss or when the valve is centred; the piston drifts and the fixed bumper only decelerates near the end. For load holding without live pressure, specify an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 0–35 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 SDAJ32X35-40B FAQ
This double-acting cylinder delivers 402.1 N push and 345.6 N pull at 0.5 MPa, or 563 N push and 483.8 N pull at 0.7 MPa. The theoretical maximum push is 82 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa at speeds of 30-500 mm/s.
The M10x1.25 R screw mechanically shortens the extend stroke by up to 40 mm, giving a usable forward range of 0 to 35 mm. It does not alter the output force, nor does it lock the piston mid-stroke; the cylinder cannot hold a load if air pressure is lost.
