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

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X40-10S
The AirTAC SDAJ80X40-10S is a double-acting compact cylinder featuring an external M20x1.5 adjustment screw that dials the extend stop from 30 to 40 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, fitting where round-body or profile cylinders cannot.
A fixed NBR bumper at each end handles end-of-stroke deceleration, though it is not an adjustable air cushion or a mid-stroke lock. This unit includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic solid-state switches in the body sensor grooves.
Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X40-10S Technical Specifications
| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X40-10S |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø80 mm |
| Max stroke | 40 mm |
| Adjustable range | 30 – 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 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 SDAJ80X40-10S Is Used
Press Fit Depth Tuning
Dial in precise 30 to 40 mm insertion depths for bearing presses on the factory floor without swapping mechanical shims, leveraging 2513.3 N of extend force.
Variable Carton Sealing
Adapt flap folding arms quickly during product changeovers, using the M20x1.5 adjuster to set the exact extend position for varying package heights.
Vertical Lift Positioning
Raise loads up to 128.1 kg with a 2:1 safety margin, fine-tuning the extend stop in place to hit elevated conveyors perfectly without re-engineering mounts.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X40-10S the Right Cylinder?
When sizing this 80 mm bore, evaluate your neighbours: stepping down to the SDAJ63 yields 1558.6 N push at 0.5 MPa, while stepping up to the SDAJ100 provides 3927 N. The SDAJ80X40-10S is optimal when you need on-site stroke tuning for frequent changeovers, providing a safe working load of roughly 1508 N (about 60 percent of its 0.5 MPa rating) or a vertical lift capacity near 128.1 kg with a 2:1 safety margin.
Confirm the 80 mm bore, 40 mm maximum stroke, 10 mm adjust window, PT3/8 port, and the female M14x1.5 rod-end thread suit your tooling. 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 mechanical stop, not a lock. 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 30–40 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 SDAJ80X40-10S FAQ
This double-acting 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 of 513 kgf at 1.0 MPa.
The M20x1.5 R screw shortens the extend stop by up to 10 mm, yielding a usable 30 to 40 mm range; retract remains full. The included -S magnet enables tracking by AirTAC reed or electronic switches.
