Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X35-40
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X35-40 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 SDAJ100X35-40
The AirTAC SDAJ100X35-40 is a double-acting compact cylinder featuring an external adjustable extend stop. An M27x2.0 adjuster screw lets you dial the forward end-position from 0 to 35 mm directly on the machine, eliminating the need for shims or part swaps during setup. The retract stroke remains full length.
Because the adjuster sets the mechanical stop rather than the piston area, output force equals a standard SDA of this bore, providing 3927 N push at 0.5 MPa. The short riveted body saves axial mounting depth where a larger profile cylinder will not fit. End shock is handled by a fixed NBR bumper, which decelerates the stroke but is not an adjustable air cushion.

|---|---|
| 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 SDAJ100X35-40 Is Used
Heavy Fixture Clamping
Dial the 0-35 mm extend stop to clamp large castings precisely without swapping shims, leveraging 3927 N of push at 0.5 MPa.
Press Fit Tuning
Adjust the mechanical stop on-site during setup to find the exact seating depth for bearings, relying on the fixed NBR bumper to absorb end shock.
Vertical Lift Jigs
Lift loads up to roughly 200.2 kg with a 2:1 safety margin, using the M27x2.0 screw to set precise upward travel limits in tight axial spaces.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X35-40 the Right Cylinder?
When sizing this 100 mm bore actuator, evaluate your force needs both ways. If 3927 N push at 0.5 MPa is excessive, stepping down to the SDAJ80 yields 2513.3 N, saving space and air. If you require maximum thrust, this model theoretically delivers up to 801 kgf at 1.0 MPa. This specific SKU lacks a piston magnet, so it cannot accept reed or electronic switches; add the -S option if sensing is required.
Engineers who need frequent changeover or trial positioning benefit most from this on-machine tuning. Note that a plain cylinder does not hold position or load when air is lost or the valve is centred; the fixed bumper only decelerates near the end. For load holding without live pressure, install an external rod lock or pilot-operated check valve. Confirm your bore, 35 mm stroke, 40 mm window, PT3/8 port, and female M18x1.5 rod thread.
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 SDAJ100X35-40 FAQ
This 100 mm bore double-acting cylinder provides 3927 N push and 3524.9 N pull at 0.5 MPa. At 0.7 MPa, push increases to 5497.8 N and pull to 4934.8 N. The theoretical maximum push is 801 kgf at 1.0 MPa.
The external M27x2.0 screw shortens the extend stroke by up to 40 mm, allowing you to set the forward stop anywhere between 0 and 35 mm. The screw creates a mechanical stop and does not alter the output force or lock the piston mid-stroke.
