Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X80-75SB
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X80-75SB 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 5 to 80 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X80-75SB
The AirTAC SDAJ100X80-75SB is a compact double-acting single-rod cylinder built for heavy-duty positioning where the extend endpoint must be dialed in on the machine. An external M27x2.0 adjuster screw lets you shorten the forward stroke by up to 75mm, yielding a usable extend range of 5 to 80mm without swapping parts. Because the mechanism only alters the mechanical stop, output force remains identical to a standard SDA of this bore, delivering 3927N of push at 0.5MPa.
This 100mm bore unit features a built-in piston magnet for AirTAC reed or electronic switches and a male M26x1.5 threaded rod end. The short riveted body saves valuable axial mounting depth compared to conventional round-body designs. End-of-travel deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion. Operating speed spans 30 to 500mm/s across a 0.15 to 1.0MPa pressure range.

| Cushion | Fixed NBR bumper (both ends) |
The adjustment screw shortens the extend stroke by up to 75 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 SDAJ100X80-75SB Is Used
Press Tooling Changeover
Dial in the 5 to 80mm extend stop during die swaps to accommodate varying material thicknesses without fabricating custom spacer shims.
Heavy Vertical Lift Dampening
Lift loads up to 200.2kg with a 2:1 safety margin, relying on the fixed NBR bumper to absorb the end-of-stroke shock on heavy descent.
Assembly Line Trial Positioning
Use the M27x2.0 adjuster screw to fine-tune the forward endpoint during initial machine commissioning until the optimal mechanical placement is found.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X80-75SB the Right Cylinder?
Selecting this 100mm bore provides a theoretical maximum push of 801kgf at 1.0MPa. Sizing both ways, stepping down to an SDAJ80 yields 2513.3N of push at 0.5MPa, whereas this 100mm model delivers 3927N at the same pressure. A computed safe working load is roughly 2356N, representing about 60% of the 0.5MPa figure, which translates to a vertical lift capacity of approximately 200.2kg with a 2:1 safety margin.
This specific configuration includes the -S magnet for position sensing and the -B male rod thread (M26x1.5). The on-machine adjustability is ideal for heavy setup lines requiring frequent changeovers. Note that a plain cylinder does not hold a load if air pressure drops or the valve centers; the fixed bumper only decelerates near the end of travel. For secure load holding without live pressure, integrate an external rod lock or a pilot-operated check valve. Porting is via PT3/8.

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 SDAJ100X80-75SB FAQ
This 100mm bore double-acting cylinder generates 3927N push and 3524.9N pull at 0.5MPa. At 0.7MPa it provides 5497.8N push and 4934.8N pull. The theoretical maximum push is 801kgf at 1.0MPa.
The external M27x2.0 screw shortens the extend stroke by up to 75mm, allowing an adjustable forward range of 5 to 80mm. The included -S magnet enables position detection using AirTAC reed or electronic solid-state switches.
