Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X40-30SB
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X40-30SB 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 10 to 40 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X40-30SB
The AirTAC SDAJ80X40-30SB is a compact double-acting single-rod cylinder engineered for on-site stroke tuning. A M20x1.5 external adjuster screw lets you dial the extend end-position anywhere between 10 and 40 mm, eliminating the need for shims or part swaps during machine commissioning. Because the adjuster sets the mechanical stop rather than the piston area, output force remains identical to a standard SDA of this bore, delivering about 2513.3 N of push force at 0.5 MPa.
This variant includes a built-in piston magnet for AirTAC reed or electronic switches and features a male M22x1.5 threaded rod end. The short riveted body saves valuable axial mounting depth where larger profile or round-body units cannot fit. End-of-stroke deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion or a mid-stroke lock.

| Adjustable range | 10 – 40 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 SDAJ80X40-30SB Is Used
Press Fit Tuning
Dial the extend stop from 10 to 40 mm to set precise insertion depths for bearings without machining custom spacers.
Vertical Lift Stops
Lift loads up to 128.1 kg safely and fine-tune the upper travel limit on-site to prevent over-travel into upper fixtures.
Changeover Adjustment
Quickly reposition the 25 mm rod end between product runs using the M20x1.5 adjuster to accommodate varying part heights.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X40-30SB the Right Cylinder?
When sizing this 80 mm bore actuator, evaluate your force requirements against its neighbours. Stepping down to the SDAJ63 yields 1558.6 N of push at 0.5 MPa, whereas moving up to the SDAJ100 provides 3927 N. This model provides a robust 2513.3 N at 0.5 MPa, translating to a safe working load of roughly 1508 N for a 2:1 safety factor, or a vertical lift capacity of about 128.1 kg.
Choose this specific configuration if your fixture requires precise extend positioning between 10 and 40 mm during changeovers. Confirm your setup needs the PT3/8 air port, the male M22x1.5 rod thread, and the integrated magnet for switch sensing. Remember that a plain compact cylinder drifts 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.

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 SDAJ80X40-30SB FAQ
At 0.5 MPa this 80 mm bore cylinder provides 2513.3 N of push force and 2267.8 N of pull force. At 0.7 MPa, push increases to 3518.6 N. The theoretical maximum push force is 513 kgf at 1.0 MPa.
The M20x1.5 screw shortens the extend stroke by up to 30 mm, yielding a usable 10 to 40 mm range. The included -S magnet enables position detection using AirTAC reed or electronic solid-state switches.
