Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X60-20S
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X60-20S 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 40 to 60 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X60-20S
The AirTAC SDAJ100X60-20S is a double-acting compact cylinder featuring an external adjustable extend stop. By turning the R (M27x2.0) screw, you can dial the forward stroke down from the 60 mm maximum to a 40 mm minimum directly on the machine, avoiding part swaps. The adjuster strictly sets the mechanical stop position; it does not alter the piston area, meaning force remains identical to a standard SDA of this bore, delivering 3927 N of push at 0.5 MPa.
This 100 mm bore actuator utilizes a short riveted body that significantly reduces axial mounting depth compared to conventional round-body alternatives, fitting into tight machinery footprints. It features a robust 32 mm piston rod, a PT3/8 air port, and a fixed NBR bumper at each end to decelerate the stroke. Because this unit includes the -S option, it contains a built-in piston magnet ready for AirTAC reed or electronic switches.

| Bore size | Ø100 mm |
| Max stroke | 60 mm |
| Adjustable range | 40 – 60 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 SDAJ100X60-20S Is Used
Heavy Press Tuning
Dialing the extend stop from 60 mm down to 40 mm allows precise positioning of heavy pressing tools without machining custom spacers.
Vertical Lift Stops
Lifting a 200 kg payload is safely managed by the 3927 N push capacity, while the external screw sets the exact raise height.
Compact Ejection
The short riveted body fits into tight machinery footprints, delivering powerful ejection force where a profile cylinder cannot fit.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X60-20S the Right Cylinder?
When sizing this actuator, evaluate the force margins of neighboring bores. Stepping down to an SDAJ80 provides 2513.3 N of push at 0.5 MPa, whereas this 100 mm option yields 3927 N, making the larger bore necessary for heavier payloads. If your application requires even more thrust, you would exceed the compact family limits and need a different format. Based on the 0.5 MPa push figure, a safe working load is roughly 2356 N (about 60 percent capacity), translating to a vertical lift capability of approximately 200.2 kg with a 2:1 safety margin.
This model is ideal for operators who need on-site stroke tuning during setup or tooling changeovers. Remember that a plain compact cylinder does not hold its load upon air loss or valve centering; the piston will drift, and the fixed bumper only decelerates near the end of travel, acting as a stop rather than a brake. For suspended or vertical loads that must be held without live pressure, install an external rod lock or a pilot-operated check valve. Confirm your required 100 mm bore, 40-60 mm adjust window, PT3/8 port, built-in magnet (S), and female M18x1.5 rod-end thread before ordering.

- ✓ 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 SDAJ100X60-20S FAQ
At 0.5 MPa, the push force is 3927 N and the pull force is 3524.9 N. At 0.7 MPa, the push is 5497.8 N and the pull is 4934.8 N. The theoretical maximum push is 801 kgf at 1.0 MPa.
The M27x2.0 adjuster screw shortens the extend stop by up to 20 mm, giving a usable range of 40-60 mm without changing force. The -S option provides a built-in piston magnet for direct mounting of AirTAC reed or electronic switches.
