Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-50S
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-50S 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 25 to 75 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-50S
The SDAJ100X75-50S is a double-acting compact cylinder featuring a 100 mm bore and a built-in piston magnet. An external M27x2.0 adjuster screw lets you dial the extend stop down from 75 mm to 25 mm directly on the machine, eliminating the need for shims or part swaps during changeovers. Because the adjuster sets the mechanical stop rather than altering the piston area, output force remains identical to a standard SDA of this size, delivering 3927 N of push at 0.5 MPa.
This riveted-body design saves substantial axial mounting depth compared to conventional round-body units, fitting into tight footprints while managing high energy. End-of-stroke deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion. The integrated magnet supports AirTAC reed or electronic switches for precise end-position sensing.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 75 mm |
| Adjustable range | 25 – 75 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 SDAJ100X75-50S Is Used
Heavy Press Fitment
Dial in the 25-75 mm extend stop on heavy press lines to accommodate varying material thicknesses without swapping out actuators.
Vertical Lifting Jigs
Lift loads up to 200.2 kg with a 2:1 margin, using the external M27x2.0 screw to set precise downward travel limits for delicate placement.
Multi-Product Changeover
Rapidly reconfigure end-of-arm tooling depth on packaging lines by turning the adjuster screw to match new container heights on the fly.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-50S the Right Cylinder?
When sizing this 100 mm bore unit, compare it against the SDAJ80, which provides 2513.3 N of push at 0.5 MPa. If your application requires less force, the 80 mm option saves space, but for heavy loads demanding roughly 2356 N of safe working load (about 60% of the 3927 N capacity at 0.5 MPa), this 100 mm cylinder is the correct choice. It can also manage a vertical lift of approximately 200.2 kg with a 2:1 safety margin.
This model is ideal for setups requiring frequent on-site stroke tuning between 25 mm and 75 mm without replacing hardware. Confirm your setup needs a PT3/8 air port, a female M18x1.5 rod-end thread, and the -S magnet option for switch sensing. Remember that a plain cylinder does not hold its load on air loss or when the valve is centred; the fixed bumper only decelerates near the end of the stroke. For load holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 25–75 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 SDAJ100X75-50S FAQ
At 0.5 MPa, this 100 mm bore cylinder provides 3927 N of push force and 3524.9 N of pull force. 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 M27x2.0 adjuster screw mechanically shortens the extend stroke window from 75 mm down to 25 mm without changing the output force. The included -S magnet allows you to mount AirTAC reed or electronic solid-state switches directly into the body sensor grooves for position feedback.
