Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X20-10
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X20-10 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 10 to 20 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X20-10
The AirTAC SDAJ100X20-10 is a double-acting compact cylinder featuring an external adjustable extend stop. A M27x2.0 adjuster screw lets you dial the forward end-position anywhere between 10 and 20 mm directly on the machine, avoiding part swaps. Because the mechanism sets the mechanical stop rather than altering the piston area, output force equals a standard SDA of this bore, delivering 3927 N push at 0.5 MPa.
The short riveted body drastically reduces axial mounting depth, fitting where larger profile cylinders cannot. This specific SKU lacks a piston magnet, so it cannot accept reed or electronic switches; add the -S option for sensing. End-of-stroke deceleration relies on a fixed NBR bumper, not an adjustable air cushion.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 20 mm |
| Adjustable range | 10 – 20 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 10 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 SDAJ100X20-10 Is Used
Heavy-Duty Pin Insertion
Dial the M27x2.0 screw to set a 15 mm extend stop, applying 3927 N of push at 0.5 MPa to seat stubborn pins without bottoming out the tooling.
Short-Depth Pressing
Leverage the compact riveted body to fit within tight machine frames, adjusting the stroke between 10 and 20 mm during initial changeover.
Vertical Lift Stops
Lift loads up to 200.2 kg with a 2:1 margin, using the external stop to prevent over-travel, provided an external check valve holds the load on air loss.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X20-10 the Right Cylinder?
When sizing this model, evaluate both neighbours. Stepping down to an SDAJ80 yields 2513.3 N push at 0.5 MPa, which may be insufficient for heavy pressing. Stepping up is impossible as 100 mm is the largest bore, making this the maximum force option in the compact family. With a 3927 N push at 0.5 MPa, the safe working load is roughly 2356 N (about 60 percent of capacity), translating to a vertical lift of approximately 200.2 kg with a 2:1 safety margin.
Choose this unit if your assembly requires precise on-machine stroke tuning within the 10-20 mm window. Confirm your port size is PT3/8 and the rod-end thread matches your fixture (female M18x1.5 or male M26x1.5). Remember that a plain cylinder drifts when air is lost; the fixed bumper only decelerates the stroke end and does not lock the load. For vertical holding without live pressure, install an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 10–20 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 SDAJ100X20-10 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 is 801 kgf at 1.0 MPa.
The M27x2.0 screw shortens the extend stop by up to 10 mm, giving a usable 10 to 20 mm range. The adjuster is a mechanical stop, not a mid-stroke lock. Without live air pressure the piston drifts, so you need an external rod lock for load holding.
