About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X55-50
The AirTAC SDAJ100X55-50 is a double-acting single-rod compact cylinder featuring an external adjustable extend stop. A M27x2.0 adjuster screw lets you dial the outward stroke on-site between 5 and 55 mm without changing parts. Because the mechanism limits travel rather than altering piston area, output matches a standard unit of this bore, providing 3927 N push at 0.5 MPa.
This model utilizes a short riveted body to minimize axial mounting depth where larger profile or round-body units fail to fit. End-of-travel deceleration relies on 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 sensing.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X55-50 |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 55 mm |
| Adjustable range | 5 – 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 50 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 SDAJ100X55-50 Is Used
Heavy Press Fit Tuning
Dial the 5 to 55 mm extend stop to set precise insertion depth for heavy press fits, leveraging the 3927 N push force without swapping mechanical shims.
High-Force Changeover Stops
Adjust the outward stroke quickly on assembly lines handling multiple product variants, relying on the fixed NBR bumper to absorb the high kinetic energy of the 32 mm rod.
Vertical Lift Positioning
Set exact lifting heights for 200.2 kg vertical loads using the M27x2.0 adjuster, ensuring positive mechanical stops while maintaining a two-to-one safety margin.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X55-50 the Right Cylinder?
When sizing this 100 mm bore actuator, consider the SDAJ80 which yields 2513.3 N push at 0.5 MPa for lighter loads. Moving up from the 80 mm option, this 100 mm unit provides a safe working load around 2356 N, calculated as roughly 60 percent of its 3927 N capacity. It also handles a vertical lift of approximately 200.2 kg when applying a two-to-one safety margin.
Operators needing frequent on-machine stroke tuning during changeovers will benefit from the 50 mm adjustment window. Remember that a plain cylinder does not hold position upon air loss or valve centering; the piston drifts and the fixed bumper only decelerates near the end. For secure load holding without live pressure, integrate an external rod lock or pilot-operated check valve. Confirm your requirements for the PT3/8 port, female M18x1.5 rod thread, and the absence of a magnet.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 5–55 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 SDAJ100X55-50 FAQ
This 100 mm bore double-acting cylinder delivers 3927 N push and 3524.9 N pull at 0.5 MPa. At 0.7 MPa, push increases to 5497.8 N and pull to 4934.8 N. The theoretical maximum push force is 801 kgf at 1.0 MPa.
Turning the external M27x2.0 screw shortens the extend stop by up to 50 mm, allowing the outward stroke to be set anywhere between 5 and 55 mm. The retract stroke remains full, and the adjuster acts purely as a mechanical stop without altering the output force.
