About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X35-30SB
The SDAJ80X35-30SB is a double-acting compact cylinder featuring an external M20x1.5 adjustment screw that lets you dial the extend stop anywhere between 5 and 35 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 significantly reduces axial mounting depth, fitting where round-body or profile cylinders cannot.
This variant includes a built-in piston magnet for AirTAC reed or electronic switches and a male M22x1.5 piston rod end. End-of-travel shock is absorbed by a fixed NBR bumper, which decelerates the piston but is not an adjustable air cushion. Operating speed ranges from 30 to 500 mm/s, and the PT3/8 air port handles the necessary flow for this high-force 80 mm bore.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø80 mm |
| Max stroke | 35 mm |
| Adjustable range | 5 – 35 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 SDAJ80X35-30SB Is Used
Multi-Height Pressing
Dial the extend stop from 5 to 35 mm to press varying material thicknesses on a single fixture, leveraging the 2513.3 N push force without swapping cylinders.
Adjustable Lift Stops
Set precise upper travel limits for heavy vertical lifts up to 128.1 kg, using the male M22x1.5 rod to secure heavy tooling while avoiding hard bottoming.
Changeover Positioning
Speed up production line changeovers by turning the M20x1.5 adjuster screw to hit new extended positions, saving axial space with its compact riveted body.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X35-30SB the Right Cylinder?
When sizing this model, consider the neighboring bores: stepping down to an SDAJ63 yields 1558.6 N of push at 0.5 MPa, while stepping up to an SDAJ100 provides 3927 N. The 80 mm bore offers a safe working load of roughly 1508 N (about 60% of its 2513.3 N capacity) and can vertically lift approximately 128.1 kg with a 2:1 safety margin. Choose this specific unit if your fixture requires on-site stroke tuning to accommodate multiple part heights without changing hardware.
Confirm the 80 mm bore, 35 mm maximum stroke, 30 mm adjustment window, and PT3/8 porting fit your envelope. This unit ships with the -S magnet for switch sensing and the -B male M22x1.5 rod thread. Note that a plain cylinder does not hold position if air pressure is lost or the valve is centered; for load holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 5–35 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 SDAJ80X35-30SB FAQ
At 0.5 MPa, this 80 mm bore cylinder provides 2513.3 N of push force and 2267.8 N of pull force. 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 30 mm, allowing you to set the stop anywhere between 5 and 35 mm without shims. The included -S magnet works with AirTAC reed or electronic solid-state switches mounted in the body grooves for position sensing.
