Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-30SB
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-30SB 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 45 to 75 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-30SB
The AirTAC SDAJ100X75-30SB is a double-acting compact cylinder featuring an external adjustable extend stop. Turning the R (M27x2.0) screw lets you dial the outward stroke down from 75 mm to 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 100 mm bore unit uses a PT3/8 port and a male-threaded piston rod (M26x1.5) to handle heavy loads. The short riveted body saves axial mounting depth where larger profile cylinders cannot fit. It includes a built-in magnet for AirTAC reed or electronic switches and relies on a fixed NBR bumper to decelerate the stroke end.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 75 mm |
| Adjustable range | 45 – 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 30 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 SDAJ100X75-30SB Is Used
Heavy Press Fit Tuning
Dial the extend stop from 75 mm down to 45 mm during press setup to find the exact insertion depth for large bearings without machining custom spacers.
Multi-Product Forming Line
Rely on the 3927 N push force at 0.5 MPa to stamp thick materials, adjusting the outward stroke on the fly when switching between deep and shallow product molds.
Vertical Lift Positioning
Lift loads up to 200.2 kg with a 2:1 safety margin, using the male M26x1.5 rod thread to secure heavy tooling while fine-tuning the raise height.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-30SB the Right Cylinder?
When sizing this model, compare it to neighbouring bores: the SDAJ80 provides 2513.3 N of push at 0.5 MPa, whereas this 100 mm bore yields 3927 N. If your application requires extreme force, the 100 mm is ideal; otherwise, step down to the 80 mm to save space. A safe working load is roughly 2356 N, which is about 60 percent of the 0.5 MPa push figure, allowing a vertical lift of approximately 200.2 kg with a 2:1 margin.
Choose this configuration if your assembly line requires frequent on-site stroke tuning between 45 and 75 mm. Confirm the PT3/8 port, the 30 mm adjustment window, and the male M26x1.5 rod thread. Note that a plain cylinder does not hold a load if air pressure drops or the valve centres; the bumper only decelerates the end of travel. For secure load holding without live pressure, install an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 45–75 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 SDAJ100X75-30SB FAQ
At 0.5 MPa it provides 3927 N push and 3524.9 N pull. At 0.7 MPa it provides 5497.8 N push and 4934.8 N pull. The theoretical maximum push is 801 kgf at 1.0 MPa.
The R (M27x2.0) screw mechanically shortens the extend end position from 75 mm down to 45 mm without changing the force. The included -S magnet allows you to track piston position using AirTAC reed or electronic switches.
