Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X45-40S
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X45-40S 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 5 to 45 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X45-40S
The AirTAC SDAJ80X45-40S is a compact double-acting single-rod cylinder featuring an external M20x1.5 adjustment screw that dials the extend stop from 5 to 45 mm directly on your equipment. Because the adjuster sets the mechanical end-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. Retract travel stays at the full 45 mm regardless of the extend setting.
Its short riveted body saves valuable axial mounting depth where larger profile or round-body units will not fit, while a fixed NBR bumper at each end absorbs end-of-stroke shock. This specific unit includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic solid-state switches along the body grooves.
Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X45-40S Technical Specifications
| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X45-40S |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø80 mm |
| Max stroke | 45 mm |
| Adjustable range | 5 – 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 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 SDAJ80X45-40S Is Used
Heavy Press Tonnage Setup
Leverage the 2513.3 N push at 0.5 MPa to seat heavy components, dialing the M20x1.5 screw across the 5-45 mm window to test multiple insertion depths without swapping hardware.
Vertical Lift Positioning
Raise payloads up to a safe 128.1 kg limit using a 2:1 margin, utilizing the built-in magnet to confirm upper travel before the fixed NBR bumper decelerates the load.
Short-Depth Assembly Station
Fit the compact riveted body into tight machine frames where axial length is restricted, adjusting the extend endpoint on the fly during new product introduction runs.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X45-40S the Right Cylinder?
When sizing this 80 mm bore, evaluate both neighbours: stepping down to the SDAJ63 yields 1558.6 N of push at 0.5 MPa, whereas moving up to the SDAJ100 provides 3927 N. The SDAJ80X45-40S is the correct choice when your application needs the 2513.3 N thrust with on-site extend tuning between 5 and 45 mm. Based on the 0.5 MPa push rating, a safe working load is roughly 1508 N (about 60 percent of capacity), translating to a vertical lift capability of approximately 128.1 kg with a 2:1 safety margin.
Operators requiring frequent changeovers or trial positioning benefit most from this adjustability. Confirm your parameters: 80 mm bore, 45 mm max stroke, 40 mm window, PT3/8 air port, female M14x1.5 rod-end thread, and the -S magnet for sensing. Note that the fixed NBR bumper only decelerates the stroke end; it does not lock the piston. If you must hold a load during air loss or valve centering, install an external rod lock or pilot-operated check valve, as the adjuster is strictly a mechanical stop.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 5–45 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 SDAJ80X45-40S FAQ
This 80 mm bore cylinder uses a PT3/8 air port. It generates 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, yielding a usable 5 to 45 mm range without changing parts. The -S code denotes a built-in piston magnet designed to trigger AirTAC reed or electronic solid-state switches.
