Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X35-30
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X35-30 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 5 to 35 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X35-30
The SDAJ100X35-30 is a 100mm bore double-acting compact cylinder featuring an external M27x2.0 adjuster screw that dials the extend stop between 5 and 35 mm directly on your machine. 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.
Built with a short riveted body, this unit saves axial mounting depth where a larger profile cylinder cannot fit. It relies on a fixed NBR bumper at each end to decelerate the stroke, which is not an adjustable air cushion. Note that this specific SKU lacks a piston magnet, so it cannot host reed or electronic switches without upgrading to the -S variant.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X35-30 |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 35 mm |
| Adjustable range | 5 – 35 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 30 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 SDAJ100X35-30 Is Used
Heavy Press Positioning
Dial in the 5 to 35 mm extend stop on-site to set precise pressing depths for thick materials without swapping mechanical spacers.
Assembly Line Changeover
Quickly reconfigure the extend endpoint for new product variants, leveraging the 3927 N push force to seat heavy components securely.
Vertical Lift Stations
Lift loads up to 200.2 kg with a 2:1 safety margin, using the M27x2.0 adjuster to set exact raise heights before applying an external check valve.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X35-30 the Right Cylinder?
When sizing this 100mm bore actuator, evaluate both directions: moving down to an SDAJ80 drops the 0.5 MPa push force to 2513.3 N, whereas this 100mm unit provides 3927 N. Based on that 3927 N output, the 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.
Choose this model if your assembly line requires frequent on-machine stroke tuning across a 5 to 35 mm window. Confirm the PT3/8 port, the female M18x1.5 rod-end thread, and the 32mm rod diameter for your mechanical linkage. Remember that a plain SDAJ does not hold position on air loss or valve centering; the fixed bumper only decelerates near the end of travel. For suspended or vertical loads, integrate an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 5–35 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 SDAJ100X35-30 FAQ
At 0.5 MPa this 100mm 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.
Turning the external M27x2.0 screw shortens the extend stroke by up to 30 mm, giving a usable extend range of 5 to 35 mm. The retract stroke remains full. This mechanism sets the mechanical stop and does not alter the output force.
