Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X45-40
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X45-40 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 SDAJ100X45-40
The AirTAC SDAJ100X45-40 is a double-acting compact cylinder featuring an external M27x2.0 adjuster screw that dials the extend stop from 5 to 45 mm directly on your machine. Because the mechanism sets the mechanical end position 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 short riveted body significantly reduces axial mounting depth compared to conventional round-body units, a crucial benefit when installing a 100 mm bore actuator in tight machinery frames. The extend stop relies on a fixed NBR bumper to absorb end-of-travel shock, meaning it is not an adjustable air cushion or a mid-stroke braking device. Operating at speeds of 30-500 mm/s, this specific SKU lacks a piston magnet and therefore cannot host reed or electronic switches without upgrading to the -S variant.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X45-40 |
|---|---|
| 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 SDAJ100X45-40 Is Used
Heavy Press Tonnage Calibration
Dial in the exact 5-45 mm extend stop during press tooling setups to apply 3927 N of forming force without replacing hard shims.
Vertical Lift Dampening
Raise a 200.2 kg payload using a 2:1 safety margin, relying on the fixed NBR bumper to absorb the end shock at the top of the stroke.
Compact Riveted Frame Integration
Fit the short 100 mm bore body into tight automated machinery footprints where axial depth is restricted but high push force is mandatory.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X45-40 the Right Cylinder?
When sizing this 100 mm bore actuator, evaluate your force requirements bidirectionally. Stepping down to an SDAJ80 yields 2513.3 N of push at 0.5 MPa, whereas this SDAJ100 provides 3927 N, making it the correct choice if your application demands a safe working load around 2356 N, which provides a 2:1 safety margin for a vertical lift of roughly 200.2 kg. Always verify your bore, 45 mm stroke, 40 mm adjustment window, PT3/8 port, and the absence of the -S magnet for sensing.
Engineers requiring on-site stroke tuning for frequent product changeovers will benefit from the 5-45 mm extend range. Note that a plain compact cylinder does not hold position or load upon air loss or valve centering; the fixed NBR bumper only decelerates the stroke end. For suspended or gravity-loaded applications, integrate an external rod lock or a pilot-operated check valve to secure the load safely.
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 SDAJ100X45-40 FAQ
This 100 mm bore cylinder delivers 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.
Turning the M27x2.0 external screw shortens the extend stroke by up to 40 mm, allowing you to set the end position anywhere between 5 and 45 mm. This SKU lacks a piston magnet, so reed or electronic switches require the -S variant.
