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

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X60-40S
The AirTAC SDAJ80X60-40S is a double-acting compact cylinder featuring an external M20x1.5 adjuster screw that dials the extend stop from 20 to 60 mm directly on your machine. By turning the R thread, you shorten the outward stroke by up to 40 mm without shims or part changes, while the retract remains full. This on-machine tuning drastically speeds up commissioning and tooling changeovers.
Because the adjuster sets the mechanical stop rather than the piston area, output force equals a standard SDA of this bore, delivering 2513.3 N push at 0.5 MPa. The short riveted body saves axial mounting depth where round-body or profile cylinders will not fit. End shock is managed by a fixed NBR bumper, which decelerates the stroke end but is not an adjustable air cushion. The integrated -S magnet supports AirTAC reed or electronic switches for position sensing.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X60-40S |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø80 mm |
| Max stroke | 60 mm |
| Adjustable range | 20 – 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 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 SDAJ80X60-40S Is Used
Press Fit Depth Calibration
Dial the M20x1.5 screw to set precise 20-60 mm extend stops for pressing bearings, leveraging the 2513.3 N push force without swapping physical spacers.
Product Divertor Changeover
Adjust the extend position on the fly to handle varying package widths on a packaging line, using the 40 mm window to fine-tune the diverting stroke rapidly.
Heavy Load Lifting Jig
Lift components up to 128.1 kg with a 2:1 safety margin, tweaking the raise height precisely to clear machine guards using the external stop screw.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X60-40S the Right Cylinder?
When sizing this 80 mm bore, evaluate both neighbours: stepping down to an SDAJ63 yields 1558.6 N push at 0.5 MPa, whereas moving up to an SDAJ100 provides 3927 N. This SDAJ80X60-40S fits between them, offering a safe working load of roughly 1508 N (about 60% of its 2513.3 N capacity) and a vertical lift capacity of approximately 128.1 kg with a 2:1 safety margin. Choose this specific model if your fixture setup requires frequent extend-position tweaking between 20 and 60 mm.
Confirm the bore, 60 mm maximum stroke, 40 mm adjustment window, and PT3/8 port match your pneumatic supply. The -S code indicates the built-in magnet is present for switch mounting, and the rod end features a female M14x1.5 thread. Remember that a plain cylinder does not hold its load on air loss or valve centring; the piston drifts and the fixed bumper only decelerates near the end. For load holding without live pressure, install an external rod lock or a pilot-operated check valve.

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 SDAJ80X60-40S FAQ
This double-acting cylinder delivers 2513.3 N push and 2267.8 N pull at 0.5 MPa, 3518.6 N push and 3175 N pull at 0.7 MPa, with a theoretical maximum push of 513 kgf at 1.0 MPa.
Turning the external R (M20x1.5) screw shortens the extend stroke by up to 40 mm, allowing usable positions between 20 and 60 mm. The -S option includes a piston magnet for AirTAC reed or electronic solid-state switches.
