Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X55-30S
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X55-30S is a genuine double-acting COMPACT cylinder (Ø100mm bore) whose extend end-position is set by an external M27×2.0 adjustment screw. You can dial the stroke anywhere from 25 to 55 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X55-30S
The AirTAC SDAJ100X55-30S is a double-acting, single-rod compact cylinder featuring an external extend stop. A M27x2.0 adjuster screw lets you dial the outward stroke anywhere between 25 and 55 mm directly on the machine. Because the mechanism only sets the mechanical stop position, output force remains identical to a standard SDA of this bore, delivering 3927 N push at 0.5 MPa.
The short riveted body drastically cuts axial mounting depth where a larger profile cylinder cannot fit. This unit includes a built-in piston magnet for AirTAC reed or electronic switches. End shock is managed by a fixed NBR bumper, which decelerates the piston near the end of travel but is not an adjustable air cushion.

| Adjustable range | 25 – 55 mm |
| Adjuster thread (R) | M27×2.0 |
| Port size | PT3/8 |
| Acting type | Double acting |
|---|---|
| Rod end thread | M18×1.5 F / M26×1.5 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 (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3525 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 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 SDAJ100X55-30S Is Used
Heavy Press Fitments
Dial the 25 to 55 mm extend stop on the R screw during press setup to test engagement depths without machining new spacers.
Vertical Lift Stations
Lift up to 200.2 kg with a 2:1 safety margin, using the fixed NBR bumper to soften the final stop at the top of the stroke.
Large Tooling Changeover
Quickly reposition the outward stroke for different heavy tooling plates on the line, relying on the full 3927 N push at 0.5 MPa.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X55-30S the Right Cylinder?
When sizing this 100 mm bore actuator, evaluate both directions: moving down, an SDAJ80 provides 2513.3 N push at 0.5 MPa, whereas this model yields 3927 N. If your application requires less force, the smaller bore saves space. This SDAJ100X55-30S variant features a PT3/8 port, a 32 mm rod, and a female M18x1.5 rod-end thread. The -S code confirms the internal magnet is present for position sensing.
Choose this adjustable-stop version if your fixture requires frequent changeovers or trial positioning. Note that a plain cylinder does not hold a load if air pressure drops or the valve centres; the piston drifts. For vertical loads, install an external rod lock or pilot-operated check valve. The mechanical stop sets the extend end, but it is not a mid-stroke brake.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 25–55 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 M27×2.0 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 SDAJ100X55-30S FAQ
At 0.5 MPa, push is 3927 N and pull is 3524.9 N. At 0.7 MPa, push is 5497.8 N and pull is 4934.8 N. The theoretical max push is 801 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa, proof pressure is 1.5 MPa, and speed ranges from 30-500 mm/s.
The M27x2.0 adjuster screw shortens the extend stroke by up to 30 mm, giving a usable range of 25-55 mm. Retract remains full stroke. The -S suffix means a magnet is built in, allowing you to mount AirTAC reed or electronic switches directly into the body sensor grooves.
