Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-20
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-20 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 55 to 75 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-20
The AirTAC SDAJ100X75-20 is a double-acting compact cylinder featuring an external adjustable extend stop. Turning the M27x2.0 adjuster screw lets you dial the outward stroke anywhere between 55 and 75 mm directly on your machine, eliminating the need for shims or part swaps. Because the adjuster only sets the mechanical stop position, the 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 relies on a short riveted body to minimize 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, so for high-energy cycles you should slow the approach or add an external shock absorber. Note that this specific SKU lacks a piston magnet and therefore cannot support reed or electronic switches.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-20 |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 75 mm |
| Adjustable range | 55 – 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 20 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 SDAJ100X75-20 Is Used
Heavy Press Tuning
Dial the 55-75 mm extend stop on a 100 mm bore press to set precise forming depth, leveraging 3927 N of thrust without swapping mechanical spacers.
Large Fixture Changeover
Adjust the outward stroke on-site to accommodate different heavy-duty workholding heights, using the compact riveted body to save valuable machine footprint.
Vertical Lift Dampening
Lift loads up to 200.2 kg with a 2:1 margin, relying on the fixed NBR bumper to absorb end shock while planning external deceleration for fast vertical cycles.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-20 the Right Cylinder?
When sizing this actuator, compare its 3927 N push at 0.5 MPa against adjacent bores. Stepping down to an SDAJ80 yields 2513.3 N, whereas this 100 mm option provides the extra thrust needed for heavier tooling. A safe working load is roughly 2356 N (about 60 percent of the 0.5 MPa figure), translating to a vertical lift capacity near 200.2 kg with a 2:1 safety margin.
This model is ideal for setups requiring on-site stroke tuning during changeovers. Confirm your requirements for a 100 mm bore, 75 mm maximum stroke, 20 mm adjust window, PT3/8 port, and female M18x1.5 rod thread. Remember that a plain cylinder drifts when air is lost or the valve centers; the fixed bumper only decelerates the end of travel and will not hold the load. For secure positioning without live pressure, install an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 55–75 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 SDAJ100X75-20 FAQ
This 100 mm bore double-acting cylinder provides 3927 N push and 3524.9 N pull at 0.5 MPa, or 5497.8 N push and 4934.8 N pull at 0.7 MPa. The theoretical maximum is 801 kgf at 1.0 MPa. It uses a PT3/8 air port.
The M27x2.0 screw acts as a mechanical stop, allowing you to shorten the extend stroke from 75 mm down to 55 mm without changing force. It is not a mid-stroke lock, and the cylinder will drift if air pressure is lost. For load holding, use an external rod lock.
