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

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X50-30S
The AirTAC SDAJ100X50-30S is a double-acting compact cylinder featuring an external adjustable extend stop. A M27x2.0 adjuster screw lets you dial the forward stroke down from the 50 mm maximum to any position between 20 and 50 mm directly on the machine, eliminating the need for shims or part swaps. Because the mechanism only sets the mechanical stop, the output force remains identical to a standard SDA of this bore, delivering 3927 N of push at 0.5 MPa.
This model features a robust 32 mm piston rod and a PT3/8 air port. Its short riveted body saves valuable axial mounting depth where a larger profile cylinder will not fit. The unit relies on a fixed NBR bumper at each end to decelerate the stroke, and the included -S piston magnet supports position sensing with AirTAC reed or electronic switches.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 50 mm |
| Adjustable range | 20 – 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 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 SDAJ100X50-30S Is Used
Heavy Press Fitment
Dial the M27x2.0 stop screw between 20 and 50 mm to set precise pressing depth for heavy bearings without swapping mechanical shims on the line.
Vertical Lift Stations
Lift payloads up to 200.2 kg with a 2:1 safety margin, using the fixed NBR bumper to soften the upper stop while relying on an external check valve for holding.
Product Changeover Jigs
Quickly reposition the extend endpoint for different part heights on a conveyor, leveraging the 3927 N push force to move robust tooling efficiently.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X50-30S the Right Cylinder?
When sizing this 100 mm bore actuator, consider the SDAJ80 as the next step down, which provides 2513.3 N of push at 0.5 MPa. The SDAJ100X50-30S is the largest standard compact option, yielding a theoretical maximum push of 801 kgf at 1.0 MPa. For applications requiring a safe working load, expect around 2356 N (about 60 percent of the 0.5 MPa figure) or a vertical lift capacity of roughly 200.2 kg with a 2:1 safety margin.
Operators needing frequent on-machine stroke tuning or trial positioning will benefit from the 20-50 mm adjustability window. Remember that a plain cylinder does not hold its load if air pressure drops or the valve is centered; the piston drifts and the fixed bumper only decelerates near the end of travel. For secure load holding without live pressure, install an external rod lock or a pilot-operated check valve. This configuration includes the S magnet option and a female M18x1.5 rod-end thread.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 20–50 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 SDAJ100X50-30S FAQ
At 0.5 MPa it provides 3927 N push and 3524.9 N pull. At 0.7 MPa it provides 5497.8 N push and 4934.8 N pull. The theoretical maximum push is 801 kgf at 1.0 MPa.
The M27x2.0 screw mechanically shortens the extend stop from 50 mm down to 20 mm without altering the pneumatic force. The built-in S magnet works with AirTAC reed or electronic solid-state switches to detect piston position along the body grooves.
