About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X55-20
The AirTAC SDAJ100X55-20 is a double-acting compact cylinder featuring an external M27x2.0 adjustment screw that dials the extend stop from 35 to 55 mm directly on your machine. Because the mechanism sets the mechanical stop rather than altering the piston area, output force remains identical to a standard 100 mm bore SDA, delivering 3927 N of push at 0.5 MPa. This makes it ideal for heavy-duty positioning tasks requiring exact endpoint control without part changes.
Its short riveted body drastically reduces axial mounting depth compared to conventional round-body cylinders, fitting into tight machinery footprints. The bore dictates a PT3/8 air port and a robust 32 mm piston rod, while end-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion. Note that this specific SKU lacks a piston magnet, so it cannot host reed or electronic switches.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X55-20 |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 55 mm |
| Adjustable range | 35 – 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 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 SDAJ100X55-20 Is Used
Heavy Press Fitment
Dial in the exact 35 to 55 mm insertion depth for heavy bearings during automated press operations, using the full 3927 N push force at 0.5 MPa without swapping shims.
Vertical Lift Stops
Lift payloads up to roughly 200.2 kg with a 2:1 safety margin, adjusting the mechanical stop on the fly to accommodate varying package heights in compact vertical stations.
Short-Depth Clamping
Utilize the short riveted body to fit heavy 100 mm bore clamping force into tight machine footprints where standard profile cylinders demand too much axial depth.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X55-20 the Right Cylinder?
When sizing this 100 mm bore actuator, evaluate your force requirements bidirectionally. Stepping down to an SDAJ80 drops the 0.5 MPa push force to 2513.3 N, whereas this 100 mm unit provides a robust 3927 N. Based on the 0.5 MPa figure, a safe working load is roughly 2356 N (about 60 percent of capacity), translating to a vertical lift capability of approximately 200.2 kg with a 2:1 safety margin. Choose this model if your fixture requires on-site stroke tuning within the 35 to 55 mm window.
Confirm your specifications before ordering: 100 mm bore, 55 mm maximum stroke, 20 mm adjustability window, PT3/8 port, female M18x1.5 rod-end thread, and no magnet. A plain SDAJ does not hold position or carry loads if air pressure drops or the valve centers; the fixed NBR bumper only decelerates near the end of travel. For suspended or vertical loads that must remain secure without live pressure, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 35–55 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 SDAJ100X55-20 FAQ
This 100 mm bore double-acting cylinder generates 3927 N push and 3524.9 N pull at 0.5 MPa, or 5497.8 N push and 4934.8 N pull at 0.7 MPa. The theoretical maximum push is 801 kgf at 1.0 MPa, and the air port size is PT3/8.
Turning the external M27x2.0 screw shortens the extend stroke by up to 20 mm, allowing you to set the endpoint anywhere between 35 and 55 mm. This screw acts strictly as a mechanical stop and does not alter force; it will not hold a load if air pressure is lost, so an external rod lock is required for suspended loads.
