Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X50-20S
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X50-20S 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 30 to 50 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X50-20S
The AirTAC SDAJ80X50-20S is a compact double-acting single-rod cylinder engineered with an external adjustable extend stop. By turning the M20x1.5 adjuster screw, you can dial the extend position on-site anywhere between 30 and 50 mm without swapping shims or parts. This on-machine tuning capability drastically simplifies commissioning and changeovers for heavy fixtures.
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 saves valuable axial mounting depth where larger profile cylinders cannot fit. End-of-stroke deceleration is handled by a fixed NBR bumper, and the included -S magnet enables position sensing with AirTAC reed or electronic switches.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø80 mm |
| Max stroke | 50 mm |
| Adjustable range | 30 – 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 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 SDAJ80X50-20S Is Used
Heavy Press Fitment
Dial the 30-50 mm extend stop on the fly to seat heavy bearings precisely without reprogramming the machine cycle.
Vertical Lift Stations
Lift payloads up to 128.1 kg with a 2:1 margin, tweaking the extend endpoint to clear varying pallet heights.
Tooling Changeover
Save axial depth in tight cells while making quick mechanical adjustments to the extend stroke during product line changeovers.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X50-20S the Right Cylinder?
When sizing this 80 mm bore actuator, evaluate your force requirements both ways. 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 SDAJ80X50-20S sits comfortably in the middle, offering a safe working load of roughly 1508 N (about 60% of its 0.5 MPa rating) 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 tuning within the 30-50 mm window. It features a PT3/8 port, a 25 mm rod, and a built-in magnet (S) for solid-state or reed sensing. Remember that the fixed NBR bumper only decelerates the stroke end; a plain cylinder does not hold a load on air loss or valve centering. For suspended loads, install an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 30–50 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.
