Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X45-50S
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X45-50S 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 0 to 45 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X45-50S
The AirTAC SDAJ80X45-50S is a compact double-acting single-rod cylinder featuring an external M20x1.5 adjuster screw that dials the extend stop from 0 to 45 mm directly on your machine. Retract remains full, while the extend end-position is set without shims or part changes. The short riveted body saves axial mounting depth where larger profile or round-body cylinders cannot fit.
Force equals a standard SDA of this 80 mm bore, delivering 2513.3 N push at 0.5 MPa, because the adjuster sets the mechanical stop, not the piston area. The bore dictates a 25 mm rod and PT3/8 port. A fixed NBR bumper decelerates the stroke end, and the built-in magnet (-S) supports AirTAC reed or electronic switches for position sensing.
Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X45-50S Technical Specifications
| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X45-50S |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø80 mm |
| Max stroke | 45 mm |
| Adjustable range | 0 – 45 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 50 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 SDAJ80X45-50S Is Used
Heavy Press Fit Tuning
Dial the 0-45 mm extend stop to set precise insertion depth for heavy press fits, leveraging the 2513.3 N push force without swapping components.
Large Pallet Diverter
Adjust the extend position on-site to accommodate varying pallet widths on a transfer line, using the compact riveted body to fit tight conveyor frames.
Vertical Lift Positioning
Securely lift loads up to 128.1 kg with a 2:1 margin and fine-tune the raise height via the M20x1.5 screw for trial positioning before final commissioning.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X45-50S the Right Cylinder?
When sizing this 80 mm bore, evaluate both neighbours: an SDAJ63 provides 1558.6 N push at 0.5 MPa, whereas an SDAJ100 yields 3927 N. This model outputs 2513.3 N, offering a safe working load of roughly 1508 N (about 60 percent of the 0.5 MPa figure) and a vertical lift capacity near 128.1 kg with a 2:1 margin. Choose this unit for heavy fixtures requiring on-site stroke tuning.
Confirm the 45 mm maximum extend, 50 mm adjustment window, PT3/8 port, and the -S magnet for reed or solid-state sensing. Note that a plain cylinder drifts when air is lost or the valve is centred; 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, install an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 0–45 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 SDAJ80X45-50S 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 and 3175 N pull at 0.7 MPa, with a theoretical maximum of 513 kgf at 1.0 MPa.
The external M20x1.5 screw shortens the extend stroke by up to 50 mm, yielding a usable 0-45 mm extend range while retract stays full. The -S option includes a built-in piston magnet for AirTAC reed or electronic switches.
