Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-50B
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-50B 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 75 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-50B
The AirTAC SDAJ100X75-50B is a compact double-acting single-rod cylinder built for high-force applications where footprint depth is restricted. It features a male-threaded M26x1.5 piston rod and a PT3/8 air port. A short riveted body saves valuable axial mounting length compared to traditional round-body or profile alternatives.
An external M27x2.0 adjustment screw lets you dial the extend stop down by up to 50 mm, yielding a usable forward range of 25 to 75 mm directly on the machine. Because the adjuster 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. The unit relies on a fixed NBR bumper to decelerate the stroke end, meaning it is not an adjustable air cushion.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 75 mm |
| Adjustable range | 25 – 75 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 50 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 SDAJ100X75-50B Is Used
Heavy Press Fit Tuning
Dial in the exact 25-75 mm extend stop during press-fit commissioning to prevent over-travel, utilizing the full 3927 N push force at 0.5 MPa without swapping shims.
High-Force Changeover Stops
Adjust the mechanical end position on the production floor when switching between heavy product variants, relying on the fixed NBR bumper to absorb end shock.
Vertical Lift Positioning
Set precise downward travel limits for vertical lifting rigs, achieving a safe working load of roughly 2356 N or a 200.2 kg vertical lift with a 2:1 margin.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-50B the Right Cylinder?
When sizing this bore, evaluate your force requirements against neighbouring models. Stepping down to the SDAJ80 yields 2513.3 N of push at 0.5 MPa, whereas this 100 mm bore provides 3927 N. If your application demands even greater thrust, you would exceed the compact series and require a larger profile format. This specific SKU includes a male M26x1.5 rod thread but lacks a piston magnet, so it cannot accept reed or electronic switches without the -S option.
Engineers who require frequent changeovers or trial positioning will benefit from the 25-75 mm on-site stop tuning. Remember that a plain compact cylinder does not hold a load when air is lost or the valve is centered; the piston drifts. For secure load holding without live pressure, integrate an external rod lock or a pilot-operated check valve. Operating speed spans 30-500 mm/s across the range.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 25–75 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 SDAJ100X75-50B FAQ
This 100 mm bore cylinder delivers 3927 N push and 3524.9 N pull at 0.5 MPa. At 0.7 MPa, push increases to 5497.8 N and pull to 4934.8 N. The theoretical maximum push is 801 kgf at 1.0 MPa.
Turning the R (M27x2.0) external screw shortens the extend stroke by up to 50 mm, providing an on-site adjustable range of 25 to 75 mm. This SKU lacks the -S magnet option, so it cannot support sensing switches.
