Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X50-40S
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X50-40S 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 10 to 50 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X50-40S
The AirTAC SDAJ80X50-40S is a double-acting compact cylinder featuring an external M20x1.5 adjuster screw that dials the extend stop directly on your machine between 10 and 50 mm. Because the adjuster sets the mechanical stop rather than altering the piston area, output force remains identical to a standard 80 mm bore SDA, delivering 2513.3 N of push at 0.5 MPa. The short riveted body saves valuable axial mounting depth where larger profile or round-body units cannot fit.
This unit includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves. End-of-travel deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion. Operating speed spans 30-500 mm/s across a 0.15-1.0 MPa pressure range.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X50-40S |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø80 mm |
| Max stroke | 50 mm |
| Adjustable range | 10 – 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 40 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 SDAJ80X50-40S Is Used
Heavy Press Fitments
Dialing the extend stop down to 10 mm allows precise insertion of heavy hardware without re-engineering the fixture, leveraging the full 2513.3 N push force.
Vertical Lift Stops
Set exact lifting heights on the fly for varying pallet sizes, safely handling loads up to 128.1 kg with a 2:1 margin before the fixed NBR bumper takes the shock.
Changeover Intervals
Quickly adjust the extend position for new product runs directly at the machine, saving axial space with its compact riveted body while retaining high force output.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X50-40S the Right Cylinder?
When sizing this model, compare its 2513.3 N push at 0.5 MPa against adjacent bores: stepping down to an SDAJ63 yields 1558.6 N, while moving up to an SDAJ100 provides 3927 N. This 80 mm bore is optimal when you need substantial force in a tight footprint, with a computed safe working load around 1508 N (60% of the 0.5 MPa push figure) or a vertical lift capacity of roughly 128.1 kg with a 2:1 safety margin.
Choose this configuration if your application requires frequent on-site stroke tuning during changeovers. Confirm your setup requires a 50 mm maximum stroke with a 40 mm adjustment window, a PT3/8 air port, and a female M14x1.5 rod-end thread. Note that a plain cylinder does not hold position on air loss; for load holding without live pressure, integrate an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 10–50 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 SDAJ80X50-40S FAQ
This 80 mm bore double-acting cylinder provides 2513.3 N push and 2267.8 N pull at 0.5 MPa, 3518.6 N push at 0.7 MPa, and a theoretical maximum of 513 kgf at 1.0 MPa.
The M20x1.5 R screw shortens the extend stop by up to 40 mm, yielding a usable 10-50 mm range without changing the force. The included -S magnet works with AirTAC reed or electronic switches for position sensing.
