Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X80-50S
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X80-50S 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 30 to 80 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X80-50S
The AirTAC SDAJ100X80-50S is a double-acting compact cylinder featuring an external adjustable extend stop. By turning the R (M27x2.0) screw, you can dial the extend position anywhere between 30 and 80 mm directly on your machine, eliminating the need for shims or part swaps. The short riveted body saves axial mounting depth where a larger profile cylinder will not fit.
Force remains identical to a standard SDA of this bore, because the adjuster sets the mechanical stop rather than altering the piston area. You get 3927 N of push at 0.5 MPa. End shock is handled by a fixed NBR bumper, which decelerates the stroke but is not an adjustable air cushion.

| 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 SDAJ100X80-50S Is Used
Heavy Press Tooling
Dial the 30-80 mm extend stop to set precise forming depth on heavy press tooling, absorbing the 3927 N push force without changing mounting hardware.
Pallet Changeover
Adjust the extend position on the fly during pallet changeover to accommodate different package sizes on a high-speed line.
Vertical Lift Jigs
Lift loads up to 200.2 kg with a 2:1 safety margin, using the external screw to fine-tune the upper stop position during commissioning.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X80-50S the Right Cylinder?
When sizing this unit, consider the SDAJ80 as the next bore down, delivering 2513.3 N of push at 0.5 MPa. If your application requires even more power, this 100 mm bore provides a theoretical maximum of 801 kgf at 1.0 MPa. Based on the 0.5 MPa push rating, a safe working load is roughly 2356 N, which allows for a vertical lift of about 200.2 kg with a 2:1 margin.
Operators who frequently change tooling or need trial positioning will benefit from the on-site stroke tuning. Note that a plain cylinder does not hold its load on air loss or when the valve is centred; the piston drifts and the bumper only decelerates near the end. For a held load, install an external rod lock or a pilot-operated check valve. This configuration includes a built-in magnet for reed or electronic switches, a PT3/8 port, and a female M18x1.5 rod-end thread.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 30–80 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 SDAJ100X80-50S 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 shortens the extend stop by up to 50 mm, giving a usable range of 30-80 mm without altering the force. The included -S magnet works with AirTAC reed or electronic switches for position sensing.
