Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X55-75S
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X55-75S 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 0 to 55 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X55-75S
The AirTAC SDAJ100X55-75S is a double-acting compact cylinder featuring an external adjustable extend stop. An M27x2.0 adjuster screw lets you dial the rod extension from 0 to 55 mm directly on the machine, eliminating the need for shims or part swaps during setup. Because the adjuster sets the mechanical stop rather than altering the piston area, output force remains identical to a standard SDA of this bore, yielding 3927 N of push at 0.5 MPa.
The short riveted body saves valuable axial mounting depth where a larger profile cylinder will not fit. End-of-stroke deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion. This unit includes a built-in piston magnet for compatibility with AirTAC reed or electronic switches, operating at speeds between 30 and 500 mm/s.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 55 mm |
| Adjustable range | 0 – 55 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 75 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 SDAJ100X55-75S Is Used
Heavy Press Fitments
Dial the 0-55 mm extend stop to set precise insertion depths for heavy bearings, leveraging the 3927 N push force without swapping mechanical spacers.
Pallet Diverter Setup
Adjust the extend position on-site to accommodate varying pallet widths on a packaging line, using the fixed NBR bumper to absorb the stop impact.
Trial Lift Positioning
Safely test vertical lift points up to 200.2 kg by tuning the stroke down from the maximum 55 mm to find the exact engagement height before locking the routine.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X55-75S the Right Cylinder?
When sizing this bore, compare its 3927 N push at 0.5 MPa against the neighboring SDAJ80, which provides 2513.3 N. Stepping up to this 100 mm bore is necessary when the smaller variant cannot overcome your process drag, while maintaining a compact footprint. A computed safe working load is roughly 2356 N, equating to a vertical lift capacity of about 200.2 kg with a 2:1 safety margin.
This model suits operators who require frequent on-machine stroke tuning during product changeovers. Remember that a plain cylinder does not hold its load on air loss or when the valve is centered; 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. Configuration: 100 mm bore, 55 mm max stroke, 75 mm window, PT3/8 port, female M18x1.5 rod thread, and an -S magnet for sensing.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 0–55 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 SDAJ100X55-75S FAQ
At 0.5 MPa this 100 mm bore cylinder 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 force is 801 kgf at 1.0 MPa.
The M27x2.0 screw shortens the extend stop by up to 75 mm, allowing usable extensions from 0 to 55 mm; retract remains full stroke. The included -S magnet works with AirTAC reed or electronic switches for position sensing.
