Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X35-20B
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X35-20B 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 15 to 35 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X35-20B
The SDAJ100X35-20B is a double-acting compact cylinder featuring an external R (M27x2.0) adjuster screw that dials the extend stop on-site between 15 and 35 mm. Because the mechanism sets the mechanical stop rather than altering the piston area, output force remains identical to a standard SDA of this bore, delivering 3927 N of push at 0.5 MPa. This SKU uses a male M26x1.5 threaded piston rod end (Ø32 mm) for secure heavy-duty load attachment.
The short riveted body saves valuable axial mounting depth where a larger profile cylinder cannot fit. End-of-travel deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion. Note that this specific model lacks a piston magnet, so it cannot support reed or electronic switches without upgrading to the -S variant.

| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 35 mm |
| Adjustable range | 15 – 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 20 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 SDAJ100X35-20B Is Used
Heavy Press Fitments
Dial in the 15-35 mm extend stop precisely during tooling changeovers to seat heavy components without applying the full 801 kgf maximum capacity.
Vertical Lift Stations
Lift approximately 200.2 kg with a 2:1 safety margin, tweaking the R screw to set exact upper travel limits for varying product heights.
Compact Clamping Beds
Utilize the short riveted body to save axial depth in tight machinery while clamping with a reliable 3927 N push force at 0.5 MPa.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X35-20B the Right Cylinder?
When sizing this 100 mm bore actuator, evaluate your force requirements bidirectionally. Stepping down to an SDAJ80 yields 2513.3 N of push at 0.5 MPa, whereas this 100 mm unit provides 3927 N. If your layout requires even greater thrust, consider a larger bore. This specific SKU includes the -B option for a male M26x1.5 rod thread and has no magnet (omit -S if sensing is unnecessary). The air connection uses a PT3/8 port.
Engineers who require precise on-machine stroke tuning during initial commissioning or frequent changeovers will benefit from the 20 mm external adjustment window. Keep in mind that a plain compact cylinder does not hold position or load upon air loss or valve centering; the fixed bumper only decelerates near the stroke end. 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 15–35 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 SDAJ100X35-20B 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. Operating pressure is 0.15-1.0 MPa with a proof pressure of 1.5 MPa, and speed ranges from 30-500 mm/s.
The external M27x2.0 adjuster screw shortens the extend stroke by up to 20 mm, allowing you to set the end position anywhere between 15 and 35 mm without changing parts. The retract stroke remains full. This SKU lacks the -S magnet option, so it cannot accept reed or electronic switches.
