Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X40-40
The AirTAC Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X40-40 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 0 to 40 mm on the machine — no shims, no part change.

About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X40-40
The AirTAC SDAJ32X40-40 is a compact double-acting single-rod cylinder featuring an external adjustable extend stop. By turning the M10x1.25 adjuster screw, you can dial the forward stroke from 0 to 40 mm directly on your machine without swapping shims or components. Because the mechanism limits travel rather than altering piston area, output force remains identical to a standard SDA of this bore, delivering 402.1 N of push at 0.5 MPa.
Its short riveted body minimizes axial mounting depth where larger profile or round-body units will not fit. The bore is hard-anodized and uses a fixed NBR bumper at each end to decelerate the stroke, though this is not an adjustable air cushion. Operating speed spans 30-500 mm/s across a 0.15-1.0 MPa pressure range.

| 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 SDAJ32X40-40 Is Used
Tooling Changeover
Dial the extend stop from 0 to 40 mm during product family swaps to reposition forming pins without machining new spacers.
Carton Flap Folding
Fine-tune the 402.1 N push stroke on-site to gently fold varying box heights without crushing the corrugated board.
Lab Test Positioning
Set precise mechanical endpoints for repetitive impact testing, leveraging the fixed NBR bumper to absorb end shock.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X40-40 the Right Cylinder?
When sizing this 32 mm bore unit, consider the neighboring options. Stepping down, the SDAJ25 provides 245.4 N of push at 0.5 MPa, whereas stepping up to an SDAJ40 yields 628.3 N at the same pressure. This SDAJ32X40-40 provides a balanced theoretical maximum of 82 kgf at 1.0 MPa, translating to a safe working load around 241 N (60% of the 0.5 MPa rating) or a vertical lift capacity of roughly 20.5 kg with a 2:1 safety margin.
Choose this specific model if your fixture requires frequent on-site stroke tuning within the 0-40 mm window. It features a PT1/8 port, a 12 mm piston rod, and a female M6x1.0 rod-end thread. Note that this SKU lacks a piston magnet, so magnetic switches cannot be used; select the -S option if sensing is required. Furthermore, the mechanical stop is not a brake—a plain cylinder drifts when air is lost, so integrate an external rod lock or pilot-operated check valve for load holding.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 0–40 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 SDAJ32X40-40 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, push increases to 563 N and pull to 483.8 N. The theoretical maximum push force is 82 kgf at 1.0 MPa.
The M10x1.25 R screw mechanically shortens the forward stroke by up to 40 mm, allowing usable extends between 0 and 40 mm without altering the 402.1 N force. This specific SKU has no piston magnet and cannot accept switches; you must append the -S code for reed or electronic sensing.
