Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X45-40B
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X45-40B 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 5 to 45 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X45-40B
The AirTAC SDAJ100X45-40B is a double-acting, single-rod compact cylinder featuring an external adjustable extend stop. An M27x2.0 adjuster screw lets you dial the outward stroke anywhere between 5 and 45 mm directly on the machine, avoiding part swaps. Because the adjuster only sets the mechanical stop, output force remains identical to a standard SDA of this bore, delivering 3927 N of push at 0.5 MPa.
This specific SKU includes a male-threaded M26x1.5 piston rod and lacks a piston magnet. The short riveted body drastically reduces axial mounting depth where larger profile cylinders cannot fit. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning the stop sets position but does not lock the load.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X45-40B |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 45 mm |
| Adjustable range | 5 – 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 40 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 SDAJ100X45-40B Is Used
Heavy Press Tonnage Setup
Dial in the exact 5 to 45 mm extend contact point for a 200 kg pressing operation without machining new spacers.
Automated Welding Clamp
Adjust the male M26x1.5 rod extension on the fly to accommodate varying weldment thicknesses on a single line.
Pallet Lift Positioning
Fine-tune the upward travel stop during commissioning to prevent over-travel when elevating heavy fixtures.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X45-40B the Right Cylinder?
When sizing this 100 mm bore actuator, evaluate your force needs against its neighbors. Dropping to an SDAJ80 reduces the push force to 2513.3 N at 0.5 MPa, whereas stepping up beyond 100 mm hits the top of this compact family. At 0.5 MPa this unit provides a safe working load of roughly 2356 N (about 60 percent of its 3927 N output) and can vertically lift approximately 200.2 kg with a 2:1 safety margin.
Choose this model if your fixture requires precise on-site stroke tuning between 5 and 45 mm. Confirm your setup needs the PT3/8 air port and the male M26x1.5 rod end. Remember that a plain cylinder drifts when air is lost or the valve centers; the fixed bumper only decelerates near the end of travel. 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 5–45 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 SDAJ100X45-40B FAQ
This 100 mm bore cylinder provides 3927 N push and 3524.9 N pull at 0.5 MPa. At 0.7 MPa it yields 5497.8 N push and 4934.8 N pull. The theoretical maximum push is 801 kgf at 1.0 MPa.
The M27x2.0 screw mechanically shortens the extend stroke by up to 40 mm, allowing you to set the outward stop anywhere from 5 to 45 mm. It does not alter the output force, and this specific SKU lacks the -S magnet required for sensing.
