Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X80-20S
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X80-20S 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 60 to 80 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X80-20S
The AirTAC SDAJ100X80-20S is a double-acting compact cylinder featuring an external adjustable extend stop. By turning the R (M27x2.0) screw, you can dial the forward stroke down from the 80 mm maximum to a 60 mm minimum directly on the machine, avoiding part swaps during setup. The short riveted body saves axial mounting depth where a larger profile cylinder will not fit.
Because the adjuster only sets the mechanical stop position, force remains identical to a standard SDA of this bore, delivering 3927 N push at 0.5 MPa. End-of-travel shock is handled by a fixed NBR bumper, which decelerates the piston but is not an adjustable air cushion. The built-in magnet (-S) supports AirTAC reed or electronic switches for position sensing.

| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 80 mm |
| Adjustable range | 60 – 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 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 SDAJ100X80-20S Is Used
Heavy Press Tooling
Dial the 60-80 mm extend stop to set precise forming depth on heavy press tooling, utilizing the 3927 N push force without changing shims.
Large Fixture Changeover
Adjust the forward endpoint on the fly during large fixture changeovers, relying on the compact riveted body to save axial space in tight cells.
Vertical Lift Stations
Lift loads up to 200.2 kg safely with a 2:1 margin, tweaking the stroke window to accommodate varying package heights in vertical lift stations.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X80-20S the Right Cylinder?
When sizing this model, look both ways: stepping down to an SDAJ80 yields 2513.3 N push at 0.5 MPa, whereas this 100 mm bore provides 3927 N. This makes the SDAJ100X80-20S the right choice when the smaller bore lacks thrust for heavy tooling. It provides a safe working load of roughly 2356 N (about 60% of the 0.5 MPa figure), translating to a vertical lift capacity near 200.2 kg with a 2:1 safety margin.
Choose this adjustable variant if your application requires frequent on-machine stroke tuning between 60 and 80 mm. Confirm the PT3/8 port, the 32 mm rod with female M18x1.5 thread, and the -S magnet. Remember that a plain cylinder drifts on air loss; the fixed bumper and mechanical stop never act as a lock. For load holding without live pressure, install an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 60–80 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 SDAJ100X80-20S FAQ
This 100 mm bore cylinder delivers 3927 N push and 3524.9 N pull at 0.5 MPa. 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 R (M27x2.0) screw shortens the extend stop by up to 20 mm, giving a usable 60-80 mm range; retract remains full. The built-in -S magnet works with AirTAC reed or electronic switches for position confirmation.
