About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X80-40S
The AirTAC SDAJ100X80-40S is a double-acting compact cylinder featuring an external M27x2.0 adjuster screw that dials the extend stop precisely between 40 and 80 mm on-site. Because the adjuster 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. The short riveted body drastically saves axial mounting depth where a larger profile cylinder will not fit.
This 100 mm bore unit uses a PT3/8 air port and a 32 mm rod, relying on a fixed NBR bumper at each end to decelerate the stroke. Equipped with a built-in piston magnet (-S), it supports AirTAC reed or electronic solid-state switches for end-position sensing. Operating pressure spans 0.15 to 1.0 MPa, with a maximum speed of 30-500 mm/s.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 80 mm |
| Adjustable range | 40 – 80 mm |
| Adjuster thread (R) | M27×2.0 |
| Port size | PT3/8 |
| Acting type | Double acting |
|---|---|
| Rod end thread | M18×1.5 F / M26×1.5 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 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 SDAJ100X80-40S Is Used
Heavy Press Fitments
Dial the 40-80 mm extend stop to seat large bearings precisely without swapping mechanical shims, leveraging 3927 N of push at 0.5 MPa.
Multi-Product Assembly Lines
Adjust the mechanical end-stop on-site during rapid product changeovers, using the 32 mm rod to drive heavy tooling plates into exact alignment.
Vertical Lift Stations
Safely raise 200.2 kg payloads with a 2:1 margin, relying on the fixed NBR bumper to decelerate the load smoothly at the end of travel.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X80-40S the Right Cylinder?
When sizing this model, consider the SDAJ80 directly below it, which yields 2513.3 N of push at 0.5 MPa—useful if your fixture requires less force and you need a narrower footprint. Conversely, the 100 mm bore chosen here provides a theoretical maximum of 801 kgf at 1.0 MPa. A computed insight for this cylinder reveals a safe working load of roughly 2356 N, equating to about 60% of the 3927 N push figure at 0.5 MPa, or a vertical lift capacity near 200.2 kg with a 2:1 safety margin.
This model is ideal for operators needing on-machine stroke tuning during frequent changeovers. Confirm your specific parameters: 100 mm bore, 80 mm stroke, 40 mm window, PT3/8 port, female M18x1.5 rod thread, and the -S magnet. Note that a plain cylinder does not hold its load on air loss or when the valve is centred; the fixed bumper only decelerates near the end. For secure load holding without live pressure, install an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 40–80 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 SDAJ100X80-40S FAQ
This 100 mm bore double-acting cylinder generates 3927 N push and 3524.9 N pull at 0.5 MPa. At 0.7 MPa, push increases to 5497.8 N and pull to 4934.8 N. The theoretical maximum push is 801 kgf at 1.0 MPa.
The external M27x2.0 screw shortens the extend stroke by up to 40 mm, allowing you to set the stop anywhere between 40 and 80 mm. The included -S magnet works with AirTAC reed or electronic switches for position sensing.
