Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X50-20
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X50-20 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 30 to 50 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X50-20
The SDAJ100X50-20 is a double-acting compact cylinder featuring a 100mm bore and an external adjustable extend stop. Turning the R (M27x2.0) screw lets you dial the forward stroke down from 50mm to 30mm directly on the machine, avoiding part swaps during setup changes. Because the adjuster only sets the mechanical stop and not the piston area, output force remains identical to a standard SDA of this size, yielding 3927N of push at 0.5MPa.
Its short riveted body drastically cuts axial mounting depth compared to conventional round-body units, fitting into heavy machinery where space is tight. The bore dictates a 32mm rod and a PT3/8 port. End-of-travel energy is managed by a fixed NBR bumper that decelerates the load, rather than an adjustable air cushion.

| Adjustable range | 30 – 50 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 20 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 SDAJ100X50-20 Is Used
Heavy Press Fitments
Dial the 30-50mm extend stop to seat large bearings precisely, leveraging the 3927N push force without over-traveling and damaging the workpiece.
Stamping Depth Calibration
Adjust the mechanical stop on the fly for different material thicknesses, using the fixed NBR bumper to absorb the 100mm bore impact energy safely.
Shallow Lift Stations
Fit the compact riveted body into tight vertical elevators where axial length is restricted, providing a safe working load of roughly 2356N for lifting tasks.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X50-20 the Right Cylinder?
When sizing this actuator, evaluate your force needs both ways. Dropping to an SDAJ80 reduces the 0.5MPa push to 2513.3N, which may undershoot heavy pressing requirements. Stepping up is not an option above 100mm in this compact family, so if 3927N is insufficient, you must increase pressure or change cylinder types entirely. This 100mm bore is ideal for applications demanding high force in a shallow footprint.
On-machine stroke tuning benefits lines with frequent format changes, letting operators set the 30-50mm window without shims. Remember that a plain SDAJ does not hold position on air loss or valve centring; the piston drifts and the fixed 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, 50mm stroke, 20mm window, PT3/8 port, female rod thread, and lack of a magnet before ordering.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 30–50 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 SDAJ100X50-20 FAQ
At 0.5MPa it provides 3927N push and 3524.9N pull. At 0.7MPa it provides 5497.8N push and 4934.8N pull. The theoretical maximum push is 801kgf at 1.0MPa.
The M27x2.0 adjuster screw mechanically shortens the extend stop from 50mm down to 30mm without changing the force. This specific SKU lacks the -S option, so it has no piston magnet and cannot accept reed or electronic switches.
