Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X15-20
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X15-20 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 0 to 15 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X15-20
The AirTAC SDAJ80X15-20 is a compact double-acting single-rod cylinder featuring an external adjustable extend stop. An M20x1.5 adjuster screw lets you dial the extend position down to 0-15 mm directly on the machine without changing parts. 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 saves valuable axial mounting depth where round-body or profile cylinders cannot fit. End-of-stroke deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion. Note that this specific SKU lacks a piston magnet, so it cannot support reed or electronic switches without upgrading to the -S variant.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X15-20 |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø80 mm |
| Max stroke | 15 mm |
| Adjustable range | 0 – 15 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 20 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 SDAJ80X15-20 Is Used
Short-Stroke Clamping
Dial the extend stop from 0 to 15 mm to clamp heavy parts precisely without over-travel, leveraging the 2513.3 N push force for rigid holding.
Vertical Lift Stops
Set exact lift heights in tight axial spaces where footprint matters, safely managing loads up to 128.1 kg with a 2:1 safety margin.
Changeover Adjustments
Quickly tune the extend position on the machine during product changeovers, avoiding part swaps while handling the high kinetic energy of an 80 mm bore.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X15-20 the Right Cylinder?
When sizing this unit, consider the SDAJ63 which offers 1558.6 N push at 0.5 MPa, or step up to the SDAJ100 providing 3927 N at 0.5 MPa. This 80 mm bore generates 2513.3 N at 0.5 MPa, yielding a safe working load of roughly 1508 N (about 60 percent of capacity) and a vertical lift capability near 128.1 kg with a 2:1 margin.
Operators requiring frequent changeover or trial positioning benefit most from the on-site stroke tuning. Remember that a plain SDAJ does not hold position upon air loss or valve centering; the piston drifts and the bumper only decelerates near the end. For secure load holding without live pressure, install an external rod lock or pilot-operated check valve. Confirm your bore, 15 mm stroke, 20 mm window, PT3/8 port, female rod thread, and lack of magnet for this configuration.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 0–15 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 SDAJ80X15-20 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 M20x1.5 adjuster screw shortens the extend stop by up to 20 mm, allowing a usable extend range of 0-15 mm. It sets the mechanical stop position without changing the force, and it is not a mid-stroke lock.
