Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X50-30
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X50-30 is a genuine double-acting COMPACT cylinder (Ø80mm bore) whose extend end-position is set by an external M20×1.5 adjustment screw. You can dial the stroke anywhere from 20 to 50 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X50-30
The AirTAC SDAJ80X50-30 is a compact double-acting single-rod cylinder built for tight axial footprints, delivering a robust 2513.3 N push at 0.5 MPa. Its riveted body design drastically cuts mounting depth where larger profile alternatives fail to fit.
An external M20x1.5 adjustment screw lets you dial the extend stop directly on the machine between 20 and 50 mm without swapping parts. The adjuster sets the mechanical stop position rather than altering the piston area, meaning output force remains identical to a standard SDA of this bore. End shock is managed solely by a fixed NBR bumper, which decelerates the stroke end but is not an adjustable air cushion.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X50-30 |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø80 mm |
| Max stroke | 50 mm |
| Adjustable range | 20 – 50 mm |
| Adjuster thread (R) | M20×1.5 |
| Port size | PT3/8 |
| Acting type | Double acting |
|---|---|
| Rod end thread | M14×1.5 F / M22×1.5 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 (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 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 SDAJ80X50-30 Is Used
Press Fit Tuning
Dial the extend stop from 20 to 50 mm on the fly to set precise insertion depths for heavy bearing press operations without machining new spacers.
Changeover Tooling
Rapidly adjust the 2513.3 N extend position during product family changeovers, saving setup time on high-mix assembly lines.
Heavy Lift Probing
Safely probe vertical loads by limiting the downward travel window, leveraging the 25 mm piston rod to handle substantial trial positioning tasks.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X50-30 the Right Cylinder?
When sizing this 80 mm bore, compare its 2513.3 N push at 0.5 MPa against the smaller SDAJ63, which yields 1558.6 N, or the larger SDAJ100 offering 3927 N. This model suits fixtures needing heavy push force but limited depth, provided the 20-50 mm extend window covers your travel. Confirm the PT3/8 port, female M14x1.5 rod thread, and the 30 mm adjustment window meet your spatial limits.
Because this SKU lacks the -S magnet, it cannot host reed or electronic switches. Note that a plain cylinder does not hold load on air loss; the fixed bumper only decelerates near the end. For suspended loads, specify an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 20–50 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 M20×1.5 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 SDAJ80X50-30 FAQ
This 80 mm bore cylinder provides 2513.3 N push and 2267.8 N pull at 0.5 MPa, and 3518.6 N push at 0.7 MPa. The theoretical maximum push is 513 kgf at 1.0 MPa.
The M20x1.5 screw shortens the extend stop from the 50 mm maximum down to 20 mm. It acts purely as a mechanical stop and does not change the force. It is not a mid-stroke lock, and the cylinder cannot hold a load without live air pressure.
