Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X50-50S
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X50-50S 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 0 to 50 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X50-50S
The AirTAC SDAJ80X50-50S is an 80 mm bore double-acting compact cylinder featuring an external M20x1.5 adjustment screw that dials the extend stop from 0 to 50 mm directly on your machine. 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. The short riveted body minimizes axial mounting depth, fitting easily where longer profile cylinders cannot.
A fixed NBR bumper at each end handles end-of-stroke deceleration, while the integrated piston magnet supports AirTAC reed or electronic solid-state switches for position sensing. The 25 mm piston rod utilizes a PT3/8 air port, operating smoothly between 30 and 500 mm/s across a 0.15 to 1.0 MPa pressure range.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X50-50S |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø80 mm |
| Max stroke | 50 mm |
| Adjustable range | 0 – 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 50 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 SDAJ80X50-50S Is Used
Heavy Press Fitment
Dial in the exact 0-50 mm extend stop for pressing heavy bearings, utilizing the 2513.3 N push force at 0.5 MPa without over-traveling.
Product Diverting
Adjust the extend position on-site to handle varying package sizes on a line, relying on the fixed NBR bumper to absorb the impact of high-speed 30-500 mm/s cycles.
Vertical Lifting Jig
Lift loads up to 128.1 kg with a 2:1 margin, fine-tuning the extend endpoint precisely where the payload needs to release without changing shims.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X50-50S the Right Cylinder?
When sizing this model, compare the thrust both ways: stepping down to the SDAJ63 yields 1558.6 N of push at 0.5 MPa, whereas moving up to the SDAJ100 provides 3927 N. This 80 mm bore generates a safe working load of roughly 1508 N (about 60% of its 2513.3 N capacity at 0.5 MPa) and can vertically lift approximately 128.1 kg with a 2:1 safety margin. Choose this unit if your fixture requires frequent on-machine stroke tuning or trial positioning without part changes.
Remember that a plain compact cylinder does not hold its load if air pressure drops or the valve is centered; the piston will drift, and the fixed bumper only decelerates near the end of travel. For load holding without live pressure, install an external rod lock or a pilot-operated check valve. Confirm your required 0-50 mm adjustment window, PT3/8 porting, 25 mm rod with female M14x1.5 thread, and the built-in magnet (-S) before ordering.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 0–50 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 SDAJ80X50-50S FAQ
This 80 mm bore cylinder features a PT3/8 air port and delivers 2513.3 N push / 2267.8 N pull at 0.5 MPa, 3518.6 N push / 3175 N pull at 0.7 MPa, and a theoretical maximum of 513 kgf at 1.0 MPa.
The M20x1.5 adjuster screw mechanically shortens the extend stop by up to 50 mm (usable range 0-50 mm) without changing the output force. The -S suffix indicates a built-in piston magnet compatible with AirTAC reed or electronic solid-state switches.
