Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X60-20S
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X60-20S 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 40 to 60 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X60-20S
The AirTAC SDAJ80X60-20S is a compact double-acting single-rod cylinder featuring an external M20x1.5 adjustment screw that dials the extend stop from 40 to 60 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 significantly reduces axial mounting depth where a larger profile cylinder cannot fit.
This 80 mm bore unit uses a PT3/8 air port and a 25 mm piston rod to cycle at 30-500 mm/s. It relies on a fixed NBR bumper at each end to decelerate the stroke, meaning it is not an adjustable air cushion. Equipped with a built-in magnet (-S), the body sensor grooves accept AirTAC reed or electronic switches for end-of-travel confirmation.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø80 mm |
| Max stroke | 60 mm |
| Adjustable range | 40 – 60 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 20 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 SDAJ80X60-20S Is Used
Heavy Press Fitment
Dial in the 40-60 mm extend stop during initial tooling setup to precisely seat heavy bearings without over-traveling, leveraging the 2513.3 N push force.
Vertical Lift Stops
Adjust the mechanical end stop on the fly for varying product heights in a vertical lift station, safely managing loads up to 128.1 kg with a 2:1 margin.
Short-Depth Clamping
Utilize the compact riveted body to fit within tight machine frames for heavy-duty clamping tasks, ensuring secure holding via the 25 mm rod.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X60-20S the Right Cylinder?
When sizing this model, evaluate your force requirements bidirectionally. Stepping down to an SDAJ63 yields 1558.6 N of push at 0.5 MPa, whereas stepping up to an SDAJ100 provides 3927 N. This SDAJ80X60-20S sits comfortably in the middle at 2513.3 N, offering a safe working load of roughly 1508 N (about 60 percent of the 0.5 MPa rating) and a vertical lift capacity near 128.1 kg with a 2:1 safety margin.
Choose this specific configuration if your fixture requires on-site extend tuning between 40 and 60 mm without swapping shims. Confirm your setup requires a PT3/8 port, a female M14x1.5 rod-end thread, and the -S magnet for switch sensing. Note that a plain cylinder drifts when air is lost or the valve is centered; 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, integrate an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 40–60 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 SDAJ80X60-20S FAQ
This 80 mm bore cylinder features a PT3/8 port and delivers 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.
The external M20x1.5 screw shortens the extend stroke by up to 20 mm, allowing you to set the end position anywhere between 40 and 60 mm. The -S option includes a built-in piston magnet for use with AirTAC reed or electronic switches in the body grooves.
