Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X85-10B
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X85-10B 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 75 to 85 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X85-10B
The AirTAC SDAJ100X85-10B is a double-acting compact cylinder featuring an external R (M27x2.0) adjuster screw that lets you dial the extend stop down from 85 mm to 75 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, yielding 3927 N of push at 0.5 MPa. The male M26x1.5 piston rod thread accommodates heavy-duty attachments, while the short riveted body drastically reduces axial mounting depth where a larger profile cylinder cannot fit.
End-of-travel deceleration relies on a fixed NBR bumper rather than an adjustable air cushion, meaning external shock absorbers may be required for high-energy approaches. Operating pressure spans 0.15 to 1.0 MPa, and the unit travels at 30-500 mm/s. Note that this specific SKU lacks a piston magnet, so position sensing is not supported without switching to the -S variant.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 85 mm |
| Adjustable range | 75 – 85 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 10 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 SDAJ100X85-10B Is Used
Heavy Press Tooling Setup
Dial in the 75-85 mm extend stop on the factory floor to precisely set the contact point for high-tonnage press tooling, avoiding part changes during initial commissioning.
Vertical Lift Positioning
Lift loads up to 200.2 kg with a 2:1 safety margin, using the M27x2.0 adjuster screw to fine-tune the exact raising height without re-engineering the fixture.
Product Changeover Lines
Adapt to varying product heights on the fly by turning the external screw to shorten the extend stroke, leveraging the 3927 N push force for robust actuation across different jigs.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X85-10B the Right Cylinder?
When sizing this 100 mm bore actuator, consider that it provides a safe working load of roughly 2356 N, which is about 60% of its 3927 N push capacity at 0.5 MPa. If you step down to an SDAJ80, your push force drops significantly to 2513.3 N at 0.5 MPa, which may be insufficient for high-mass tooling. Conversely, the 100 mm bore provides a vertical lift capacity of approximately 200.2 kg with a 2:1 safety margin, making it the optimal choice for heavy lifting within tight spatial constraints.
This model is specified with a 10 mm adjustable window (75-85 mm), a PT3/8 air port, and a male-threaded M26x1.5 rod end (-B). It is ideal for applications requiring on-site stroke tuning during changeovers. Remember that a plain SDAJ does not hold position upon air loss or valve centering; the fixed bumper only decelerates the stroke end. For load holding without live pressure, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 75–85 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 SDAJ100X85-10B FAQ
This 100 mm bore cylinder features a PT3/8 port and delivers 3927 N push / 3524.9 N pull at 0.5 MPa, 5497.8 N push / 4934.8 N pull at 0.7 MPa, and a theoretical maximum of 801 kgf at 1.0 MPa.
The R (M27x2.0) screw mechanically shortens the extend stroke from 85 mm down to 75 mm without changing the force output. The -B code indicates a male M26x1.5 piston rod thread. This SKU lacks the -S magnet, so it cannot support reed or electronic switches.
