Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X85-40B
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X85-40B 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 45 to 85 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X85-40B
The AirTAC SDAJ100X85-40B is a double-acting compact cylinder featuring an external adjustable extend stop. An M27x2.0 adjuster screw lets you dial the forward stroke down by up to 40 mm, yielding a usable range of 45 to 85 mm directly on your machinery. 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 utilizes a short riveted body to minimize axial mounting depth where larger profile cylinders cannot fit. It comes equipped with a male M26x1.5 piston rod thread and a PT3/8 air port. Deceleration at the end of travel 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 without upgrading to the -S variant.

| 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 SDAJ100X85-40B Is Used
Heavy Press Fit Tooling
Dial the 45-85 mm extend stop precisely for seating large bearings, leveraging the 3927 N push force without overshooting the part.
Multi-Product Assembly Lines
Quickly reconfigure the mechanical stop during product changeovers to accommodate varying large-component heights without swapping cylinders.
Vertical Lift Stations
Lift loads up to 200.2 kg with a 2:1 margin, using the male M26x1.5 rod to handle heavy vertical elevation tasks in confined footprints.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X85-40B the Right Cylinder?
When sizing this actuator, evaluate both neighboring bores to match your space and force requirements. Stepping down to the SDAJ80 yields 2513.3 N of push at 0.5 MPa, whereas this 100 mm option provides 3927 N. For context, the computed safe working load is approximately 2356 N (about 60 percent of the 0.5 MPa push figure), translating to a vertical lift capacity of roughly 200.2 kg with a 2:1 safety margin.
Choose this model if your application requires frequent on-site stroke tuning between 45 and 85 mm during changeovers. Confirm your setup needs the male M26x1.5 rod thread and the PT3/8 port. Remember that a plain cylinder does not hold position or load when air is lost or the valve is centered; the bumper only decelerates near the end of travel. For secure load holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 45–85 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 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 SDAJ100X85-40B FAQ
At 0.5 MPa it provides 3927 N of push and 3524.9 N of pull. At 0.7 MPa the push increases to 5497.8 N and the pull to 4934.8 N. The theoretical maximum push is 801 kgf at 1.0 MPa.
Turning the M27x2.0 external screw shortens the extend end position by up to 40 mm, allowing you to set the stroke anywhere between 45 and 85 mm. This mechanism only sets the stop position and does not alter the force or act as a mid-stroke lock.
