Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X30-30B
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X30-30B is a genuine double-acting COMPACT cylinder (Ø80mm bore) whose extend end-position is set by an external M20×1.5 adjustment screw. You can dial the stroke anywhere from 0 to 30 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X30-30B
The AirTAC SDAJ80X30-30B is a double-acting compact cylinder featuring an external adjustable extend stop. By turning the R (M20x1.5) screw, you can dial the extend position from 0 to 30 mm directly on your machine without changing parts. Because the adjuster sets the mechanical stop rather than the piston area, force remains identical to a standard SDA of this bore, delivering 2513.3 N of push at 0.5 MPa.
This unit utilizes a short riveted body to minimize axial mounting depth where round-body or profile cylinders cannot fit. It comes with a male M22x1.5 piston rod thread (option B) and a PT3/8 air port. End-of-stroke deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion. Note that this specific SKU lacks a piston magnet, so it cannot support reed or electronic switches.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø80 mm |
| Max stroke | 30 mm |
| Adjustable range | 0 – 30 mm |
| Adjuster thread (R) | M20×1.5 |
| Port size | PT3/8 |
| Acting type | Double acting |
|---|---|
| Rod end thread | M14×1.5 F / M22×1.5 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 30 mm. Force is unchanged from a standard SDA of the same bore. Specifications follow the official AirTAC SDAJ datasheet.
Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 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 SDAJ80X30-30B Is Used
Heavy Press Fitments
Dial in the 0-30 mm extend stop during machine commissioning to precisely seat large bearings without over-traveling, leveraging the 2513.3 N push force.
Vertical Lift Stops
Safely raise payloads up to 128.1 kg with a 2:1 margin, using the external R screw to set exact upper limits in tight vertical spaces.
Changeover Assemblies
Rapidly adjust the extend position for different product sizes on a packaging line, avoiding part swaps while the male M22x1.5 rod handles the load.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X30-30B the Right Cylinder?
When sizing this model, compare its 2513.3 N push at 0.5 MPa against adjacent bores. Stepping down to the SDAJ63 yields 1558.6 N, whereas moving up to the SDAJ100 provides 3927 N. Based on the 0.5 MPa figure, a safe working load is roughly 1508 N (about 60 percent of capacity), translating to a vertical lift capability of approximately 128.1 kg with a 2:1 safety margin.
This cylinder is perfect for applications requiring frequent on-site stroke tuning or trial positioning. Keep in mind that a plain SDAJ does not hold position or load when air is lost or the valve is centered; the fixed bumper only decelerates near the end of travel. For load holding without live pressure, install an external rod lock or pilot-operated check valve. Confirm your requirements for the 80 mm bore, 30 mm maximum stroke, 30 mm adjustment window, PT3/8 port, male M22x1.5 rod, and lack of a magnet.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 0–30 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 M20×1.5 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 SDAJ80X30-30B FAQ
At 0.5 MPa, it provides 2513.3 N of push and 2267.8 N of pull. At 0.7 MPa, push increases to 3518.6 N and pull to 3175 N. The theoretical maximum push is 513 kgf at 1.0 MPa.
The M20x1.5 adjuster screw mechanically limits the extend stroke, allowing you to set the end position anywhere between 0 and 30 mm. It does not alter the output force, and the retract stroke remains full length.
