Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X45-20S
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X45-20S 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 25 to 45 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X45-20S
The AirTAC SDAJ100X45-20S is a compact double-acting single-rod cylinder built for tight axial spaces, delivering a massive 3927 N push at 0.5 MPa. Its short riveted body saves mounting depth where a larger profile body would fail to fit. A built-in piston magnet enables position sensing with AirTAC reed or electronic switches.
An external M27x2.0 adjuster screw lets you dial the extend stop down from the 45 mm maximum to 25 mm directly on the machine. The adjuster sets the mechanical stop position without altering the bore area, meaning force remains identical to a standard SDA of this size. End shock is handled solely by a fixed NBR bumper, not an adjustable air cushion.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X45-20S |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 45 mm |
| Adjustable range | 25 – 45 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 SDAJ100X45-20S Is Used
Heavy Press Fitments
Dial the extend stop from 25 to 45 mm to set precise pressing depth for heavy 200.2 kg vertical assemblies without swapping mechanical shims.
Large Mold Changeover
Quickly reposition the rod end for varying mold thicknesses on a 3927 N press line, cutting setup time using the M27x2.0 adjuster.
Vertical Lift Stops
Set exact raise heights for heavy lifting platforms, relying on the fixed NBR bumper to absorb the impact of substantial payloads at the end of travel.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X45-20S the Right Cylinder?
When sizing this 100 mm bore, look at the SDAJ80 which yields 2513.3 N push at 0.5 MPa. If your payload demands the full 3927 N push, this 100 mm option is the correct choice. A safe working load is roughly 2356 N, equating to a vertical lift of about 200.2 kg with a 2:1 safety margin.
Operators requiring on-site stroke tuning between 25 and 45 mm will benefit from the external R screw. Confirm your PT3/8 port, female M18x1.5 rod thread, and the -S magnet for switch readiness. Note that a plain cylinder drifts on air loss; the bumper only decelerates near the end and is not a lock, so add an external rod lock or pilot-operated check valve for load holding.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 25–45 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 SDAJ100X45-20S FAQ
This 100 mm bore cylinder provides 3927 N push and 3524.9 N pull at 0.5 MPa, 5497.8 N push and 4934.8 N pull at 0.7 MPa, with a theoretical maximum push of 801 kgf at 1.0 MPa.
The M27x2.0 screw shortens the extend stop by up to 20 mm, giving a usable 25-45 mm range without changing force. The included -S magnet works with AirTAC reed or electronic switches for end-position sensing.
