Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X35-40B
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X35-40B 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 35 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X35-40B
The AirTAC SDAJ100X35-40B is a compact double-acting single-rod cylinder built for heavy-duty positioning where axial mounting depth is restricted. Its short riveted body saves space, while the external R (M27x2.0) adjuster screw lets you dial the extend stop down from a 35 mm maximum to zero directly on the machine. This on-site tuning removes the need for shims or part swaps during commissioning.
Because the adjuster sets the mechanical stop rather than the piston area, output force equals a standard SDA of this bore, delivering 3927 N push at 0.5 MPa. The bore dictates a PT3/8 port and a Ø32 mm rod. This SKU uses a male M26x1.5 rod thread (option B) and lacks a piston magnet, so it cannot host reed or electronic switches without the -S variant.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X35-40B |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 35 mm |
| Adjustable range | 0 – 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 40 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 SDAJ100X35-40B Is Used
Heavy Press Tonnage Setup
Dial in the exact 0-35 mm extend stop on a 100 mm bore press fixture, leveraging the 3927 N push at 0.5 MPa to seat heavy components without overshooting the target depth.
Automated Welding Clamp
Use the male M26x1.5 rod thread to secure a robust clamping arm, adjusting the extend position on the fly to accommodate varying weldment thicknesses during line changeovers.
Vertical Lift Positioning
Safely raise a 200.2 kg payload with a 2:1 margin, relying on the external R (M27x2.0) screw to fine-tune the lift height precisely without changing mounting hardware.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X35-40B the Right Cylinder?
When sizing this actuator, compare its 3927 N push at 0.5 MPa against the neighbouring bores. Stepping down, the SDAJ80 provides 2513.3 N at the same pressure; moving up would exceed this series' capacity. This 100 mm bore fits applications requiring a safe working load around 2356 N (roughly 60 percent of the 0.5 MPa push figure) or a vertical lift of 200.2 kg with a 2:1 margin. Choose this specific model if your fixture requires a male M26x1.5 rod end and on-site stroke tuning within the 0 to 35 mm window.
Confirm the 100 mm bore, 35 mm stroke, 40 mm adjustment window, and PT3/8 port suit your pneumatic layout. Note that a plain SDAJ does not hold position or carry load if air pressure drops or the valve centres; the fixed NBR bumper only decelerates the stroke end. For load holding without live pressure, install an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 0–35 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 SDAJ100X35-40B FAQ
This 100 mm bore double-acting cylinder provides 3927 N push and 3524.9 N pull at 0.5 MPa, and 5497.8 N push and 4934.8 N pull at 0.7 MPa. The theoretical maximum push is 801 kgf at 1.0 MPa.
The R (M27x2.0) screw shortens the extend stop by up to 40 mm, allowing you to set the usable extend stroke anywhere from 0 to 35 mm. The retract stroke remains full, and the adjuster acts purely as a mechanical stop, not a mid-stroke lock.
