Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X35-30B
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X35-30B 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 SDAJ100X35-30B
The AirTAC SDAJ100X35-30B is a compact double-acting single-rod cylinder built for heavy-duty positioning where footprint matters. An external M27x2.0 adjuster screw lets you dial the extend stop down from 35 mm to 5 mm directly on the machine, avoiding part swaps during changeovers. Because the mechanism sets the mechanical stop rather than altering piston area, output force matches a standard 100 mm bore SDA at 3927 N push at 0.5 MPa.
This variant features a male M26x1.5 piston rod thread and a PT3/8 air port. The short riveted body minimizes axial mounting depth in tight fixtures. End-of-travel shock is handled by a fixed NBR bumper that decelerates the load, which is not an adjustable air cushion. Note that this SKU lacks a piston magnet, so it cannot host reed or electronic switches.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X35-30B |
|---|---|
| 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 SDAJ100X35-30B Is Used
Heavy Press Fitments
Dial the extend stop from 35 mm down to 5 mm to test multiple insertion depths on thick steel plates without machining new spacers.
Multi-Product Clamping
Leverage the 3927 N push at 0.5 MPa to secure large castings, adjusting the mechanical stop quickly between short and tall part families.
Vertical Lift Stations
Raise loads up to 200.2 kg with a 2:1 safety margin, using the male M26x1.5 rod to handle heavy tooling while fine-tuning the lift height.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X35-30B the Right Cylinder?
When sizing this unit, look both ways: moving down to an 80 mm bore drops the 0.5 MPa push to 2513.3 N, while this 100 mm bore yields 3927 N. Based on that 0.5 MPa figure, a safe working load is roughly 2356 N (about 60 percent of capacity), translating to a 200.2 kg vertical lift with a 2:1 safety margin. Choose the SDAJ100X35-30B if your setup requires on-site stroke tuning within the 5 to 35 mm window.
Confirm your parameters: 100 mm bore, 35 mm max stroke, 30 mm adjustability window, PT3/8 port, male M26x1.5 rod, and no magnet. A plain cylinder drifts when air is lost or the valve centers, as the fixed bumper only decelerates near the end and the R screw acts as a stop, not a lock. For secure load 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 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 SDAJ100X35-30B FAQ
At 0.5 MPa it 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.
Turning the M27x2.0 screw shortens the extend stroke by up to 30 mm, allowing the rod to stop anywhere between 5 mm and 35 mm. It sets the mechanical stop position and does not alter force or lock the piston mid-stroke.
