Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X120-50SB
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X120-50SB 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 70 to 120 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X120-50SB
The AirTAC SDAJ100X120-50SB is a compact double-acting single-rod cylinder featuring an on-site adjustable extend stop. A built-in piston magnet enables position sensing with AirTAC reed or electronic switches, while the male M26x1.5 rod thread accommodates rigid mechanical attachments. The short riveted body minimizes axial footprint, fitting where larger profile or round-body cylinders cannot.
By turning the external R (M27x2.0) adjuster screw, you shorten the forward stroke anywhere between 70 and 120 mm without changing parts. The stop sets the end position, leaving force unchanged at 3927 N push at 0.5 MPa. End-of-travel deceleration relies on a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 120 mm |
| Adjustable range | 70 – 120 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 SDAJ100X120-50SB Is Used
Heavy Press Fitments
Dial in the exact 70-120 mm extend stop during press assembly commissioning to prevent overtravel on dense materials, utilizing the full 3927 N push force.
Automated Welding Clamps
Adjust the mechanical stop on the fly for varying fixture thicknesses. The fixed NBR bumper absorbs the 30-500 mm/s approach shock without needing external cushions.
Vertical Lift Stations
Lift payloads up to 200.2 kg safely with a 2:1 margin. Note that an external pilot-operated check valve is required to prevent drifting down if air pressure drops.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X120-50SB the Right Cylinder?
When sizing this 100 mm bore actuator, consider the SDAJ80 as the next step down, providing 2513.3 N push at 0.5 MPa for lighter duties. Moving up is not an option as this is the largest bore in the SDA family. The SDAJ100X120-50SB yields a safe working load of roughly 2356 N, or about 60 percent of its 0.5 MPa rating, translating to a vertical lift capacity near 200.2 kg with a 2:1 safety margin.
Operators requiring frequent changeovers or trial positioning benefit from the 50 mm adjustment window. Remember that a standard cylinder 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, integrate an external rod lock or pilot-operated check valve. This configuration includes the S magnet and B male rod thread, with a PT3/8 port.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 70–120 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 SDAJ100X120-50SB 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.
The external M27x2.0 screw mechanically shortens the extend stroke from the 120 mm maximum down to 70 mm without altering the force output. The included S option provides a built-in piston magnet for tracking position with AirTAC reed or electronic solid-state switches.
