Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X45-40
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X45-40 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 SDAJ80X45-40
The AirTAC SDAJ80X45-40 is a compact double-acting single-rod cylinder featuring an external M20x1.5 adjustment screw that dials the extend stop anywhere between 5 and 45 mm directly on your machine. 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 drastically reduces axial mounting depth where larger profile or round-body units cannot fit.
This 80 mm bore unit uses a PT3/8 air port and a 25 mm piston rod to handle substantial loads, with a fixed NBR bumper at each end to decelerate the stroke. It operates between 0.15 and 1.0 MPa at speeds of 30-500 mm/s. Note that this specific SKU lacks a piston magnet and cannot accept magnetic switches; specifying the -S option adds that sensing capability.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X45-40 |
|---|---|
| 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 SDAJ80X45-40 Is Used
Heavy Press Tuning
Dial the 5-45 mm extend stop on a 2513.3 N press to precisely set material deformation depth during initial tooling setup and changeovers.
Vertical Lift Stops
Lift loads up to 128.1 kg with a 2:1 margin, adjusting the mechanical end-stop to hit exact elevation targets without swapping cylinders.
Compact High-Force Clamping
Fit the short riveted body into tight machine cells to deliver 3518.6 N of clamping force at 0.7 MPa while fine-tuning the grip reach.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X45-40 the Right Cylinder?
When sizing this unit, compare its 2513.3 N push force at 0.5 MPa against neighboring bores: the smaller SDAJ63 provides 1558.6 N, while the larger SDAJ100 yields 3927 N. Choose this 80 mm model when your application demands a safe working load of approximately 1508 N (about 60% of the 0.5 MPa rating) or a vertical lift capacity near 128.1 kg with a 2:1 safety margin. It is ideal for setups requiring frequent on-machine stroke tuning without part changes.
Confirm your requirements for an 80 mm bore, 45 mm maximum stroke, 40 mm adjust window, PT3/8 port, female rod thread, and no magnet. Remember that a plain SDAJ does not hold position if air pressure drops or the valve centers—the fixed bumper only decelerates near the end of travel. For secure load holding without live pressure, integrate an external rod lock or a pilot-operated check valve.
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 SDAJ80X45-40 FAQ
This 80 mm bore cylinder delivers 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. The adjustment screw does not alter these force values.
Turning the M20x1.5 external screw shortens the extend end-position by up to 40 mm, allowing you to set the stroke anywhere from 5 to 45 mm on-site. This SKU lacks a piston magnet, so it cannot use reed or electronic switches; select the -S option if sensing is required.
