Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X65-40
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X65-40 is a genuine double-acting COMPACT cylinder (Ø100mm bore) whose extend end-position is set by an external M27×2.0 adjustment screw. You can dial the stroke anywhere from 25 to 65 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X65-40
The AirTAC SDAJ100X65-40 is a compact double-acting single-rod cylinder engineered for heavy-duty positioning where the extend endpoint must be dialed in on the machine. An external R (M27x2.0) adjuster screw lets you shorten the forward stroke anywhere between 25 and 65 mm without swapping shims or parts. Because the adjuster sets the mechanical stop rather than altering the piston area, output force remains identical to a standard SDA of this bore, providing 3927 N of push at 0.5 MPa.
This 100 mm bore unit features a short riveted body that drastically cuts axial mounting depth in tight machinery envelopes. It uses a fixed NBR bumper at each end to absorb end-of-stroke shock rather than relying on a tunable air cushion. Operating pressure spans 0.15 to 1.0 MPa, and the unit safely handles a working load of roughly 2356 N, which is about 60 percent of its 0.5 MPa capacity.

| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 65 mm |
| Adjustable range | 25 – 65 mm |
| Adjuster thread (R) | M27×2.0 |
| Port size | PT3/8 |
| Acting type | Double acting |
|---|---|
| Rod end thread | M18×1.5 F / M26×1.5 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 (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3525 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 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 SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X65-40 Is Used
Press Tooling Setup
Dial in the 25-65 mm extend stop during press tooling changeovers to apply exactly 3927 N of push at 0.5 MPa without part changes.
Heavy Workpiece Clamping
Securely clamp large castings by fine-tuning the mechanical stop on the fly, leveraging the 100 mm bore's massive 801 kgf maximum output.
Vertical Lift Jigs
Execute precise vertical lifts up to roughly 200.2 kg with a 2:1 safety margin, adjusting the endpoint to match varying workpiece heights.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X65-40 the Right Cylinder?
When sizing this model, compare its 3927 N push at 0.5 MPa against adjacent bores. Stepping down, the SDAJ80 delivers 2513.3 N at the same pressure, making the 100 mm bore necessary for heavier payloads. Stepping up is not available in this compact family, so 100 mm represents the maximum force ceiling here. This specific SKU lacks the -S magnet code, meaning it cannot accept AirTAC reed or electronic switches; select the -S variant if position feedback is required.
Choose this 65 mm stroke with a 40 mm window for lines requiring frequent format changeovers or trial positioning. Note that a plain cylinder does not hold its load when air is lost or the valve is centered—the piston drifts, as the fixed bumper only decelerates near the end of travel. For suspended or vertical loads, incorporate an external rod lock or a pilot-operated check valve. Confirm your requirements for the PT3/8 port, female M18x1.5 rod-end thread, and the 30-500 mm/s speed range before finalizing.

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 M27×2.0 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 SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X65-40 FAQ
This 100 mm bore double-acting cylinder generates 3927 N push and 3524.9 N pull at 0.5 MPa, or 5497.8 N push and 4934.8 N pull at 0.7 MPa. The theoretical maximum output is 801 kgf at 1.0 MPa. The air port is PT3/8.
Turning the external M27x2.0 screw shortens the extend stroke by up to 40 mm, allowing you to set the forward endpoint anywhere between 25 and 65 mm. The retract stroke remains full, and the adjuster acts purely as a mechanical stop without changing the cylinder's force output.
