About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X55-10
The AirTAC SDAJ80X55-10 is a double-acting compact cylinder featuring an external M20x1.5 adjustment screw that lets you dial the extend stop directly on the machine. You can set the outward travel anywhere between 45 and 55 mm without swapping parts or adding shims, making end-position tuning effortless during commissioning. The mechanism sets the mechanical stop without altering the piston area, delivering 2513.3 N of push force at 0.5 MPa.
Built with a short riveted body, this unit saves axial mounting depth where a larger profile cylinder would never fit. It relies on a fixed NBR bumper at each end to decelerate the stroke, which is not an adjustable air cushion. Because this specific SKU lacks the -S magnet option, it cannot accept reed or electronic switches for position sensing.
Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X55-10 Technical Specifications
| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X55-10 |
|---|---|
| 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 SDAJ80X55-10 Is Used
Heavy Press Fitment
Dial in the exact 45-55 mm extension for pressing heavy bearings, using the full 2513.3 N push force at 0.5 MPa without overshooting the part.
Large Package Diverter
Adjust the stroke stop on-site to accommodate varying pallet sizes on a line, ensuring the 25 mm rod pushes heavy loads accurately without retooling.
Vertical Lift Stop
Lift loads up to 128.1 kg with a 2:1 margin and fine-tune the downward extend position, relying on the mechanical stop rather than shims for height control.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X55-10 the Right Cylinder?
When sizing this 80 mm bore, compare it both ways: stepping down to an SDAJ63 yields 1558.6 N of push at 0.5 MPa, while stepping up to an SDAJ100 provides 3927 N. This model's 2513.3 N push at 0.5 MPa translates to a safe working load of roughly 1508 N, or a vertical lift capacity of about 128.1 kg with a 2:1 safety margin. Choose this unit if your assembly requires heavy push force plus on-site stroke tuning across a 10 mm window.
Confirm the bore, 55 mm maximum stroke, 10 mm adjustability, and PT3/8 port match your pneumatic layout. Note that this plain cylinder does not hold position or load when air is lost or the valve is centred; the fixed bumper only decelerates near the end of travel. For load holding without live pressure, you must integrate 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 SDAJ80X55-10 FAQ
This 80 mm bore double-acting cylinder provides 2513.3 N push and 2267.8 N pull at 0.5 MPa. At 0.7 MPa, push increases to 3518.6 N. The theoretical maximum push force is 513 kgf at 1.0 MPa.
Turning the M20x1.5 external screw shortens the extend stroke by up to 10 mm, allowing you to set the outward travel anywhere between 45 and 55 mm. The retract stroke remains full, and the adjuster acts as a mechanical stop, not a mid-stroke lock.
