Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X120-20
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X120-20 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 100 to 120 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X120-20
The AirTAC SDAJ100X120-20 is a compact double-acting single-rod cylinder featuring an external adjustable extend stop. Turning the R (M27x2.0) screw lets you dial the extend position anywhere between 100 and 120 mm directly on the machine, avoiding part swaps. Because the adjuster sets the mechanical stop rather than the piston area, output force remains identical to a standard SDA of this bore, delivering 3927 N push at 0.5 MPa.
This 100 mm bore unit uses a PT3/8 port and a 32 mm piston rod to handle heavy loads within a short riveted body that saves axial mounting depth. End shock is managed by a fixed NBR bumper, which decelerates the stroke end but is not an adjustable air cushion. Note that this specific SKU lacks a piston magnet, so it cannot host reed or electronic switches without upgrading to the -S variant.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 120 mm |
| Adjustable range | 100 – 120 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 SDAJ100X120-20 Is Used
Heavy Press Tooling
Dial the extend stop from 100 to 120 mm to set exact contact depth on heavy press tools without machining new spacers.
Large Fixture Changeover
Re-adjust the 100 mm bore actuator on the factory floor during product line changeovers to accommodate different large part heights.
Vertical Lift Platforms
Lift loads up to 200.2 kg with a 2:1 margin, using the external stop to prevent overtravel on vertical lifting platforms.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X120-20 the Right Cylinder?
When sizing this actuator, compare its 3927 N push at 0.5 MPa against adjacent bores. Stepping down to the SDAJ80 yields 2513.3 N, whereas this 100 mm option provides the extra thrust needed for heavier tooling. A safe working load is approximately 2356 N, representing about 60 percent of the 0.5 MPa figure, and it can vertically lift roughly 200.2 kg with a 2:1 safety margin.
Choose this model if your fixture requires precise on-site stroke tuning between 100 and 120 mm during setup or changeover. Keep in mind that a plain cylinder does not hold its load on air loss or when the valve is centered, as the piston drifts and the bumper only decelerates near the end. For suspended loads, integrate an external rod lock or a pilot-operated check valve. Confirm your bore, 120 mm maximum stroke, 20 mm window, PT3/8 port, female M18x1.5 rod thread, and lack of magnet before ordering.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 100–120 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 SDAJ100X120-20 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 force is 801 kgf at 1.0 MPa.
The R (M27x2.0) screw mechanically shortens the extend end position from the 120 mm maximum down to 100 mm. It acts as a hard stop and does not alter the thrust or lock the piston mid-stroke.
