Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X80-40B
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X80-40B 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 40 to 80 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X80-40B
The AirTAC SDAJ100X80-40B is a double-acting compact cylinder featuring an external adjustable extend stop. A M27x2.0 adjuster screw lets you dial the outward stroke anywhere between 40 and 80 mm directly on the machine. Because the mechanism only limits travel, output force remains identical to a standard 100 mm bore SDA, delivering 3927 N of push at 0.5 MPa.
This variant uses a male M26x1.5 piston rod thread and a PT3/8 air port. The short riveted body significantly reduces axial mounting depth compared to conventional round-body units. End-of-travel deceleration is handled by a fixed NBR bumper, which is not an adjustable air cushion. Note that this specific SKU lacks a piston magnet, so it cannot support reed or electronic switches.

| Adjustable range | 40 – 80 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 SDAJ100X80-40B Is Used
Heavy Press Tuning
Dial in the exact 40 to 80 mm extend position during press changeovers, utilizing the full 3927 N push force at 0.5 MPa without swapping mechanical spacers.
Large Fixture Clamping
Secure oversized workholding fixtures where axial space is restricted, benefiting from the compact riveted body and the robust 32 mm male rod end.
Vertical Lift Positioning
Adjust the downward stop on the fly for varying material heights, achieving a safe working load of roughly 2356 N for a 2:1 vertical lift margin.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X80-40B the Right Cylinder?
When sizing this actuator, compare its 3927 N push at 0.5 MPa against adjacent bores. Stepping down, the SDAJ80 provides 2513.3 N, which may be insufficient for heavy loads, whereas stepping up is impossible as 100 mm is the largest available bore in this series. This model is ideal for setups requiring on-site stroke tuning to perfect end positions without machining new parts. Keep in mind the male M26x1.5 rod thread and 40 mm adjustment window for your mounting interfaces.
Regarding load management, the fixed NBR bumper only decelerates the piston near the end of travel and the R screw acts solely as a mechanical stop. A plain cylinder does not hold position if air pressure drops or the valve is centered. To safely suspend loads, you must integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 40–80 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 SDAJ100X80-40B FAQ
At 0.5 MPa, this 100 mm bore cylinder provides 3927 N of push force and 3524.9 N of pull force. At 0.7 MPa, push increases to 5497.8 N and pull to 4934.8 N. The theoretical maximum push force is 801 kgf at 1.0 MPa.
The M27x2.0 adjuster screw mechanically shortens the extend stop from the 80 mm maximum down to 40 mm without altering the output force. This specific SKU lacks the -S magnet option, so it cannot accept AirTAC reed or electronic switches.
