Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X60-20B
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X60-20B 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 SDAJ80X60-20B
The AirTAC SDAJ80X60-20B is a double-acting compact cylinder featuring an external extend stop, allowing you to dial the forward stroke between 40 and 60 mm directly at the machine. It uses a short riveted body to minimize axial mounting depth where larger profile or round-body units fail to fit. The M20x1.5 adjuster screw sets the mechanical end position without shims or part changes.
Force remains identical to a standard SDA of this bore, delivering 2513.3 N push at 0.5 MPa because the adjuster limits travel, not the piston area. This specific SKU includes a male M22x1.5 piston rod thread and lacks a piston magnet, meaning it cannot support reed or electronic switches. End-of-travel deceleration is handled by a fixed NBR bumper, not an adjustable air cushion.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X60-20B |
|---|---|
| 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 SDAJ80X60-20B Is Used
Press Fit Dial-In
Ideal for press operations needing exact insertion depth, letting operators tweak the 40-60 mm extend stop on the fly to accommodate material tolerances without swapping parts.
Heavy Fixture Changeover
Supports rapid format changes on automated lines where the 2513.3 N push force handles robust clamping, and the external screw quickly resets the forward position for new product runs.
Vertical Lift Positioning
Useful for lifting loads up to 128.1 kg with a 2:1 margin, where the mechanical stop ensures the lift plate halts at a precise height before the retract cycle begins.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X60-20B the Right Cylinder?
When sizing this unit, consider the neighboring bores: stepping down to the SDAJ63 yields 1558.6 N push at 0.5 MPa, while the larger SDAJ100 provides 3927 N. The 80 mm bore offers a safe working load of roughly 1508 N (about 60 percent of the 0.5 MPa figure), translating to a vertical lift capacity near 128.1 kg with a 2:1 safety margin. Choose this model if your fixture requires precise on-site extend tuning between 40 and 60 mm.
Confirm the 80 mm bore, 60 mm maximum stroke, 20 mm adjustment window, and PT3/8 air port. This variant features a male M22x1.5 rod end and no magnet. Note that a plain cylinder does not hold a load if air pressure drops or the valve centers; the piston drifts and the bumper only decelerates near the end. For secure load holding without live pressure, install an external rod lock or a 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 SDAJ80X60-20B FAQ
At 0.5 MPa this 80 mm bore cylinder provides 2513.3 N push and 2267.8 N pull. At 0.7 MPa it provides 3518.6 N push and 3175 N pull. The theoretical maximum push force is 513 kgf at 1.0 MPa.
Turning the M20x1.5 adjuster screw shortens the forward stroke by up to 20 mm, setting the extend stop anywhere between 40 and 60 mm. The retract stroke remains full, and the screw acts only as a mechanical stop, not a mid-stroke lock.
