Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X55-10S
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X55-10S 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 45 to 55 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X55-10S
The AirTAC SDAJ80X55-10S is a double-acting compact cylinder featuring an external M20x1.5 adjustment screw that dials the extend stop from 45 to 55 mm directly on your equipment. Because the adjuster sets the mechanical stop rather than altering the piston area, output force remains identical to a standard SDA of this bore, delivering 2513.3 N of push at 0.5 MPa. Retract travel stays at the full 55 mm.
Its short riveted body drastically reduces axial mounting depth compared to conventional round-body or profile cylinders, fitting into tight machinery footprints. The integrated -S piston magnet supports AirTAC reed or electronic switches for precise end-position sensing. End-of-stroke deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X55-10S |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø80 mm |
| Max stroke | 55 mm |
| Adjustable range | 45 – 55 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 10 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 SDAJ80X55-10S Is Used
Press Fit Calibration
Dial the 45-55 mm extend stop during setup to precisely seat bearings, leveraging the 2513.3 N push force without swapping mechanical shims.
Variable Depth Flap Folding
Adjust the stroke end on the fly to accommodate different carton sizes, using the integrated magnet to confirm the fold position.
Heavy Fixture Positioning
Secure large production fixtures in tight axial spaces using the compact riveted body, fine-tuning the 55 mm maximum reach to clear tooling.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X55-10S the Right Cylinder?
When sizing this 80 mm bore, evaluate your neighbours: stepping down to the SDAJ63 yields 1558.6 N of push at 0.5 MPa, while stepping up to the SDAJ100 provides 3927 N. This SDAJ80X55-10S sits comfortably in the middle at 2513.3 N, offering a safe working load of roughly 1508 N (about 60 percent of its 0.5 MPa capacity) and a vertical lift capability of approximately 128.1 kg with a 2:1 safety margin.
Choose this specific model if your assembly requires frequent on-machine stroke tuning within the 45-55 mm window to perfect part pressing or forming depths. Confirm your setup needs a PT3/8 air port, a 25 mm piston rod with a female M14x1.5 thread, and the -S magnet for switch integration. Remember that a plain cylinder drifts when air is lost or the valve is centred; the fixed bumper only decelerates near the end and the R screw is a mechanical stop, not a lock. For 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 45–55 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 SDAJ80X55-10S FAQ
This double-acting cylinder delivers 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. It operates between 0.15 and 1.0 MPa, with a speed range of 30-500 mm/s and a fixed NBR bumper for end deceleration.
The external M20x1.5 screw shortens the extend stroke by up to 10 mm, giving an adjustable range of 45 to 55 mm. It functions strictly as a mechanical stop and does not alter the output force. The included -S piston magnet is fully compatible with AirTAC reed or electronic solid-state switches for position sensing.
