Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X35-30S
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X35-30S 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 5 to 35 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X35-30S
The AirTAC SDAJ80X35-30S is a compact double-acting single-rod cylinder engineered for on-site extend position tuning. By turning the external M20x1.5 adjuster screw, you shorten the forward stop anywhere within a 5 to 35 mm window without swapping shims or components. Because the mechanism restricts travel rather than piston area, output matches a standard 80 mm bore, yielding 2513.3 N of push at 0.5 MPa.
Its riveted body geometry minimizes axial mounting depth, fitting where larger profile cylinders cannot. The unit relies on a fixed NBR bumper to absorb end-of-stroke shock rather than an adjustable air cushion. Equipped with a built-in piston magnet, this variant directly supports AirTAC reed or electronic solid-state switches for precise end-position confirmation.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø80 mm |
| Max stroke | 35 mm |
| Adjustable range | 5 – 35 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 SDAJ80X35-30S Is Used
Press Fit Calibration
Dial the extend stop from 5 to 35 mm during initial tooling setup to find the exact press depth, leveraging 2513.3 N of force without changing mounting hardware.
Product Diverting
Adjust the actuation length on the fly for different package sizes on a packaging line, ensuring positive stops while the fixed NBR bumper absorbs the kinetic energy.
Pallet Lift Positioning
Set precise lifting heights for varying pallet thicknesses, safely managing vertical loads up to 128.1 kg when paired with an external check valve for load holding.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X35-30S the Right Cylinder?
When sizing this actuator, evaluate both neighbouring bores against your 0.5 MPa requirements. Stepping down, the 63 mm variant provides 1558.6 N of push; moving up, the 100 mm bore delivers 3927 N. This 80 mm model outputs 2513.3 N, making it suitable for a safe working load of roughly 1508 N or vertically lifting about 128.1 kg with a 2:1 safety margin.
Choose this specific configuration if your fixture requires frequent changeovers or trial positioning within the 5 to 35 mm travel band. Confirm your setup needs the PT3/8 air port, the 25 mm piston rod, and the female M14x1.5 rod-end thread. Remember that the mechanical stop and fixed bumper do not secure a load; if air pressure drops, you must utilize an external rod lock or pilot-operated check valve to prevent drifting.

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 SDAJ80X35-30S FAQ
At 0.5 MPa this 80 mm bore cylinder 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 force is 513 kgf at 1.0 MPa.
The M20x1.5 external screw mechanically limits the extend stroke, allowing you to set the end position anywhere between 5 and 35 mm. The included -S magnet enables detection by AirTAC reed or electronic switches; the screw itself does not alter force or lock mid-stroke.
