Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X30-20B
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X30-20B 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 10 to 30 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X30-20B
The AirTAC SDAJ100X30-20B is a double-acting compact cylinder featuring an external M27x2.0 adjuster screw that dials the extend stop from 10 to 30 mm directly on your machine. Because the mechanism 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.
Its riveted body geometry minimizes axial mounting depth where larger bore units cannot fit. This specific SKU includes a male M26x1.5 piston rod end and lacks a piston magnet, meaning it cannot host reed or solid-state switches without switching to the -S variant. End-of-travel deceleration is handled solely by a fixed NBR bumper, not an adjustable air cushion.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X30-20B |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 30 mm |
| Adjustable range | 10 – 30 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 SDAJ100X30-20B Is Used
Press Fit Dialing
Fine-tune the 10 to 30 mm extend stop during heavy press fit changeovers to accommodate slight component height variations without machining new spacers.
Heavy Lift Lowering
Safely position a 200 kg vertical lift payload by adjusting the mechanical stop to prevent over-travel, relying on the 3927 N push force at 0.5 MPa.
Compact End Stops
Utilize the short riveted body to fit heavy-duty end-stopping logic into tight machinery frames where standard profile cylinders demand too much axial depth.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X30-20B the Right Cylinder?
When sizing this 100 mm bore actuator, evaluate both neighbors: dropping down to an SDAJ80 yields 2513.3 N of push at 0.5 MPa, whereas this SDAJ100X30-20B provides 3927 N. With a safe working load around 2356 N—roughly 60 percent of its 0.5 MPa rating—it can vertically lift approximately 200.2 kg with a 2:1 safety margin. Choose this model if your setup demands heavy inline positioning combined with on-site stroke tuning.
Confirm your parameters before ordering: 100 mm bore, 30 mm maximum stroke, 20 mm adjust window, PT3/8 air port, and a male M26x1.5 rod thread. Remember that a plain cylinder drifts when air is lost or a valve centers; the fixed bumper only decelerates the stroke end and does not lock the load. For suspended loads, integrate an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 10–30 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 SDAJ100X30-20B FAQ
At 0.5 MPa this 100 mm bore cylinder provides 3927 N of push and 3524.9 N of pull. At 0.7 MPa it delivers 5497.8 N push and 4934.8 N pull. The theoretical maximum output is 801 kgf at 1.0 MPa.
The M27x2.0 R screw shortens the extend end position by up to 20 mm, allowing you to set the stroke anywhere between 10 and 30 mm. This SKU lacks the -S magnet option, so it cannot accept reed or electronic switches.
