Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X80-50
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X80-50 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 SDAJ100X80-50
The AirTAC SDAJ100X80-50 is a double-acting compact cylinder featuring an external adjustable extend stop. Turning the R (M27x2.0) screw lets you dial the forward stroke down from 80 mm to 30 mm directly on the machine, eliminating the need for shims or part swaps during changeovers. The short riveted body saves axial mounting depth where a larger profile cylinder will not fit.
Because the adjuster sets the mechanical stop rather than the piston area, output force remains identical to a standard SDA of this bore, delivering 3927 N push at 0.5 MPa. End-of-travel deceleration relies on a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion. This specific SKU lacks a piston magnet, so it cannot host reed or electronic switches without upgrading to the -S variant.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 80 mm |
| Adjustable range | 30 – 80 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 SDAJ100X80-50 Is Used
Heavy Press Tooling
Dial the 30-80 mm extend stop to set precise forming depth on heavy press tooling, leveraging the 3927 N push at 0.5 MPa without swapping mechanical spacers.
Pallet Format Changeover
Adjust the forward stroke on the fly during pallet format changeover, accommodating various product sizes while the compact riveted body minimizes machine footprint.
Vertical Lift Fixtures
Lift vertical fixtures up to 200.2 kg with a 2:1 safety margin, using the mechanical stop to set exact raise heights between 30 and 80 mm.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X80-50 the Right Cylinder?
When sizing this unit, evaluate both neighbours: stepping down to an SDAJ80 yields 2513.3 N push at 0.5 MPa, whereas this 100 mm bore provides 3927 N. A safe working load is roughly 2356 N, assuming a 60 percent safety factor of the 0.5 MPa push figure, translating to a vertical lift capacity of about 200.2 kg with a 2:1 margin. Choose the 100 mm bore when your setup-heavy line requires that extra thrust for moving heavy fixtures.
On-machine stroke tuning via the M27x2.0 adjuster is invaluable for trial positioning and rapid format changes. Remember that a plain cylinder does not hold its load on air loss or valve centred; the piston drifts and the fixed bumper only decelerates near the end. For load holding without live pressure, install an external rod lock or a pilot-operated check valve. This configuration includes a 100 mm bore, 80 mm stroke, 50 mm adjust window, PT3/8 port, female M18x1.5 rod thread, and no magnet.
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 SDAJ100X80-50 FAQ
This 100 mm bore cylinder delivers 3927 N push and 3524.9 N pull at 0.5 MPa, 5497.8 N push and 4934.8 N pull at 0.7 MPa, with a theoretical maximum push of 801 kgf at 1.0 MPa.
The external M27x2.0 screw acts as a mechanical stop, allowing you to shorten the extend stroke from the full 80 mm down to 30 mm. It does not alter the output force and is not a mid-stroke lock.
