Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X40-30
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X40-30 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 10 to 40 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X40-30
The AirTAC SDAJ80X40-30 is a compact double-acting single-rod cylinder featuring an external M20x1.5 adjustment screw that dials the extend stop directly on your machine. You can tune the forward end-position anywhere from 10 mm to 40 mm without swapping shims or parts. Because the adjuster sets the mechanical stop rather than the piston area, output force equals a standard SDA of this bore, delivering 2513.3 N push at 0.5 MPa.
Its riveted body design minimizes axial mounting depth where larger profile cylinders cannot fit. End-of-stroke deceleration relies on a fixed NBR bumper rather than an adjustable air cushion. Note this specific SKU lacks a piston magnet, so it cannot host reed or electronic switches without upgrading to the -S variant.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X40-30 |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø80 mm |
| Max stroke | 40 mm |
| Adjustable range | 10 – 40 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 30 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 SDAJ80X40-30 Is Used
Machining Clamp Depth
Dial the extend stop from 10 to 40 mm to perfect clamp depth on raw castings of varying widths without reprogramming the motion controller.
Heavy Vertical Lift
Lift payloads up to 128.1 kg safely using the 2513.3 N extend force, relying on the fixed NBR bumper to soften the final stopping impact.
Press Fit Tuning
Fine-tune the pressing depth of bearings on an assembly line by turning the M20x1.5 screw, ensuring precise insertion without over-stressing parts.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X40-30 the Right Cylinder?
When sizing this 80 mm bore, look at both neighbours. Stepping down to SDAJ63 yields 1558.6 N push at 0.5 MPa, whereas moving up to SDAJ100 provides 3927 N. This SDAJ80X40-30 hits a solid middle ground, offering a safe working load around 1508 N (roughly 60 percent of its 0.5 MPa rating) and a vertical lift capacity near 128.1 kg with a 2:1 safety margin.
Choose this model if your fixture requires frequent on-machine stroke tuning across a 10-40 mm window. It uses a PT3/8 port and a female M14x1.5 rod end. Remember that a plain cylinder drifts when air is lost or the valve centres; the fixed bumper only decelerates near the end and the R screw is a stop, not a lock. For secure 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 10–40 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 SDAJ80X40-30 FAQ
This 80 mm bore cylinder provides 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 is 513 kgf at 1.0 MPa.
The external M20x1.5 screw mechanically shortens the extend stroke by up to 30 mm, allowing you to set the forward stop anywhere between 10 mm and 40 mm. This specific SKU lacks a piston magnet, so it cannot accept reed or electronic switches unless you upgrade to the -S option.
