About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X45-10S
The AirTAC SDAJ80X45-10S is a compact double-acting single-rod cylinder featuring an external M20x1.5 adjuster screw that lets you dial the extend stop directly on the machine between 35 and 45 mm. Because the mechanism 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 drastically reduces axial mounting depth, fitting where larger profile or round-body units cannot.
End-of-travel deceleration relies on a fixed NBR bumper rather than an adjustable air cushion, meaning high-speed approaches may require external shock absorbers. This specific configuration includes a built-in piston magnet for position sensing with AirTAC reed or electronic switches. Operating pressure spans 0.15 to 1.0 MPa, and the unit supports a safe working load of roughly 1508 N, which translates to a vertical lift capacity of about 128.1 kg with a 2:1 safety margin.

| Adjustable range | 35 – 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 10 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 SDAJ80X45-10S Is Used
Press Fit Dialing
Allows operators to fine-tune the 35-45 mm extend stop on a bearing press, ensuring precise contact force without swapping mechanical shims during product changeovers.
Carton Flap Folding
Provides adjustable mechanical reach for folding varying box sizes, relying on the 2513.3 N push force to cleanly tuck heavy cardboard flaps before taping.
Heavy Pallet Lifts
Delivers a safe vertical lift of approximately 128.1 kg with a 2:1 margin, letting technicians set the exact 35-45 mm raise height needed for delicate pallet stacking.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X45-10S the Right Cylinder?
When sizing this 80 mm bore, stepping down to the SDAJ63 yields 1558.6 N of push at 0.5 MPa, whereas moving up to the SDAJ100 provides 3927 N. Choose this 80 mm model when your application demands the 2513.3 N thrust and requires on-site stroke tuning within the 35-45 mm range to perfect part contact. The PT3/8 port and 25 mm rod handle substantial flow and load capacities.
This unit is ideal for setup-heavy lines needing frequent changeover or trial positioning. Remember that the fixed NBR bumper and M20x1.5 adjuster only provide mechanical stopping and end-deceleration; they do not secure the load. If air pressure drops or the valve centers, the piston will drift, so integrate an external rod lock or pilot-operated check valve for load holding. Configuration confirmed: 80 mm bore, 45 mm stroke, 10 mm window, PT3/8 port, female M14x1.5 rod thread, built-in magnet, male M22x1.5 thread option.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 35–45 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 SDAJ80X45-10S FAQ
This 80 mm bore cylinder features a PT3/8 air port and generates 2513.3 N push and 2267.8 N pull at 0.5 MPa. At 0.7 MPa, push increases to 3518.6 N and pull to 3175 N. The theoretical maximum push force is 513 kgf at 1.0 MPa.
The external M20x1.5 screw shortens the extend stroke by up to 10 mm, allowing you to set the end position anywhere between 35 and 45 mm without changing parts. The included -S magnet works with AirTAC reed or electronic switches for position sensing, while the fixed NBR bumper handles end deceleration.
