The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X15-10SB 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 5 to 15 mm on the machine — no shims, no part change.
The AirTAC SDAJ100X15-10SB is a compact double-acting single-rod cylinder built for tight axial spaces. An external M27x2.0 adjuster screw lets you dial the extend stop down from the 15mm maximum to a 5mm minimum directly on the machine. Because the screw sets the mechanical stop rather than altering the piston area, output force remains identical to a standard SDA of this bore, delivering 3927 N of push at 0.5 MPa.
This variant includes a built-in piston magnet for AirTAC reed or electronic switches and a male M26x1.5 rod thread. The short riveted body drastically reduces mounting depth where a larger profile cylinder cannot fit. End-of-stroke deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion.

The adjustment screw shortens the extend stroke by up to 10 mm. Force is unchanged from a standard SDA of the same bore. Specifications follow the official AirTAC SDAJ datasheet.
| 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.

Dial the 5-15mm extend stop to precisely set the crush depth on heavy-gauge materials, leveraging the 3927 N push force at 0.5 MPa for consistent forming results.
Lift loads up to roughly 200.2 kg with a 2:1 safety margin, using the male M26x1.5 rod thread to securely attach heavy tooling while adjusting the stop to avoid over-travel.
Fit the compact riveted body into dense automated machinery, using the 5-15mm adjustment window to perfect the clamping position of varied workpieces on the fly.
Choosing this 100mm bore provides massive thrust in a compact footprint. If your application can operate with less force, sizing down to the SDAJ80 yields 2513.3 N of push at 0.5 MPa, saving valuable space. Conversely, this SDAJ100 represents the upper limit of the series, offering a theoretical maximum of 801 kgf at 1.0 MPa. A safe working load is roughly 2356 N, which is about 60% of the 0.5 MPa push figure, allowing a vertical lift of approximately 200.2 kg with a 2:1 safety margin.
This model is ideal for setups requiring frequent on-machine stroke tuning between 5 and 15 mm without changing parts. Confirm the PT3/8 port, the 10mm adjustment window, and the male M26x1.5 rod end for your mounting interface. Note that a plain cylinder does not hold its load on air loss or when a valve is centred; the piston drifts and the fixed bumper only decelerates near the end of the stroke. For secure load holding without live pressure, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
At 0.5 MPa, the push force is 3927 N and the pull force is 3524.9 N. At 0.7 MPa, the push is 5497.8 N and the pull is 4934.8 N. The theoretical maximum push force is 801 kgf at 1.0 MPa.
The M27x2.0 adjuster screw mechanically shortens the extend stroke from the 15mm maximum down to 5mm without changing the output force. The included -S magnet allows you to track piston position using AirTAC reed or electronic solid-state switches mounted in the body grooves.
