Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X85-20S
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X85-20S 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 65 to 85 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X85-20S
The AirTAC SDAJ100X85-20S is a compact double-acting single-rod cylinder featuring an external R (M27x2.0) adjuster screw. Turning this screw lets you dial the extend stop on-site between 65 and 85 mm without swapping shims or parts. The short riveted body saves valuable axial mounting depth where a larger profile cylinder simply will not fit. Force remains identical to a standard SDA of this bore, delivering 3927 N push at 0.5 MPa, because the adjuster sets the mechanical stop rather than altering the piston area.
This 100 mm bore unit uses a PT3/8 air port and a 32 mm piston rod. End-of-stroke deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion. Equipped with a built-in piston magnet, the unit supports AirTAC reed or electronic switches for precise position sensing.

| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 85 mm |
| Adjustable range | 65 – 85 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 20 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 SDAJ100X85-20S Is Used
Heavy Press Tonnage Setup
Dial in the 65-85 mm extend stop on the factory floor to apply precise 3927 N clamping force without re-machining tooling plates.
Vertical Lift Dampening
Lift loads up to 200.2 kg with a 2:1 margin, using the fixed NBR bumper to absorb end shock while the R screw sets the exact lower stop.
Multi-Product Changeover Lines
Quickly adjust the extend position by up to 20 mm between different product runs, saving axial space in compact assembly cells.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X85-20S the Right Cylinder?
When sizing this actuator, evaluate your force requirements carefully. Dropping down to the SDAJ80 bore yields 2513.3 N push at 0.5 MPa, whereas this 100 mm bore provides 3927 N. A computed safe working load is approximately 2356 N, representing about 60 percent of the 0.5 MPa push figure, which allows a 2:1 safety margin for vertical lifts up to roughly 200.2 kg.
This model is ideal for heavy setups requiring frequent on-machine stroke tuning during changeovers. Remember that a plain cylinder does not hold its load on air loss or when the valve is centred; the piston drifts and the bumper only decelerates near the end. For secure load holding without live pressure, integrate an external rod lock or a pilot-operated check valve. Confirm your bore, 85 mm stroke, 20 mm window, PT3/8 port, female rod thread, and the built-in magnet.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 65–85 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 SDAJ100X85-20S FAQ
At 0.5 MPa it provides 3927 N push and 3524.9 N pull. At 0.7 MPa it provides 5497.8 N push and 4934.8 N pull. The theoretical maximum push force is 801 kgf at 1.0 MPa.
The M27x2.0 adjuster screw shortens the extend stroke by up to 20 mm, giving a usable range of 65 to 85 mm. The included magnet works with AirTAC reed or electronic switches for position sensing.
