Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X80-40SB
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X80-40SB 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 SDAJ100X80-40SB
The AirTAC SDAJ100X80-40SB is a double-acting, single-rod compact cylinder featuring an external extend stop. A M27x2.0 adjuster screw lets you dial the outward stroke down by 40 mm, yielding a usable 40 to 80 mm extension right at the machine without swapping shims or components. Because the adjuster only dictates the mechanical stop position rather than the piston area, output force remains identical to a standard SDA of this bore, delivering 3927 N of push at 0.5 MPa.
This variant includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches, plus a male M26x1.5 thread (-B) on the 32 mm rod. The short riveted body minimizes axial footprint where space is tight. End-of-travel deceleration relies on a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion.

| 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 SDAJ100X80-40SB Is Used
Heavy Press Fitments
Dial the M27x2.0 stop from 40 to 80 mm to set precise insertion depths for large bearings without changing tooling.
Vertical Lift Stations
Lift payloads up to 200.2 kg safely; use the male M26x1.5 rod for robust mounting in overhead lifting jigs.
Large Fixture Clamping
Clamp oversized castings securely using 3927 N of force, adjusting the outward reach on the fly to fit part variations.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X80-40SB the Right Cylinder?
When sizing this unit, compare its 3927 N push at 0.5 MPa against adjacent bores. Stepping down, the SDAJ80 provides 2513.3 N, making the 100 mm bore necessary for heavier payloads. A practical safe working load is roughly 2356 N, assuming a 60 percent safety factor of the 0.5 MPa push figure, translating to a vertical lift capacity near 200.2 kg with a 2:1 margin. Choose this specific model when your assembly requires frequent on-site stroke tuning across a 40 to 80 mm window.
Confirm the 100 mm bore, 80 mm maximum stroke, 40 mm adjustment window, and PT3/8 port. The male M26x1.5 rod end and internal magnet are active. Remember that a standard cylinder does not hold position upon air loss or valve centering; the piston drifts. For suspended or vertical loads, integrate an external rod lock or pilot-operated check valve, as the fixed bumper only decelerates near the end of travel and provides no braking function.
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 SDAJ100X80-40SB FAQ
At 0.5 MPa it provides 3927 N push and 3524.9 N pull. 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. Operating pressure spans 0.15 to 1.0 MPa, with a speed range of 30 to 500 mm/s.
The R (M27x2.0) screw mechanically limits the extend stroke, allowing you to set the outward position anywhere between 40 and 80 mm. The built-in magnet (-S) works with AirTAC reed or electronic switches for position sensing. The screw acts strictly as a stop and does not alter force.
