Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X70-40SB
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X70-40SB 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 30 to 70 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X70-40SB
The AirTAC SDAJ100X70-40SB is a double-acting compact cylinder featuring an external adjustable extend stop. Turning the R (M27x2.0) screw lets you dial the forward end-position anywhere between 30 and 70 mm directly on your machine, eliminating the need for shims or part swaps. Because the adjuster only sets the mechanical stop rather than altering the piston area, output force remains identical to a standard SDA of this bore, delivering about 3927 N of push at 0.5 MPa.
This 100 mm bore unit packs substantial power into a short riveted body, saving valuable axial mounting depth where larger profile or round-body units cannot fit. It includes a built-in piston magnet for AirTAC reed or electronic switches and a male M26x1.5 rod thread. End-of-travel deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion.

| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 70 mm |
| Adjustable range | 30 – 70 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 SDAJ100X70-40SB Is Used
Press Fit Tooling
Dial the 30-70 mm extend stop to seat bearings precisely without changing out hard stops, leveraging the 3927 N push at 0.5 MPa for reliable insertion.
Heavy Vertical Lifts
Raise platforms or platens weighing up to 200.2 kg safely using a 2:1 margin, tweaking the mechanical stop to prevent over-travel at the top position.
Product Changeover
Adapt quickly to new part heights on a machining line by spinning the R screw to shorten the forward stroke, saving setup time across production runs.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X70-40SB the Right Cylinder?
When sizing this actuator, compare its 3927 N push at 0.5 MPa against neighboring bores. Stepping down to the SDAJ80 yields 2513.3 N, whereas this 100 mm option provides the extra thrust needed for heavier tooling. With a safe working load of roughly 2356 N (about 60 percent of the 0.5 MPa figure) and a vertical lift capacity of approximately 200.2 kg at a 2:1 safety margin, it suits demanding press and lift stations. Choose this specific model if your assembly requires frequent on-machine stroke tuning to accommodate varying material thicknesses.
Confirm the 100 mm bore, 70 mm maximum stroke, and 40 mm adjust window fit your envelope. The air port is PT3/8, and this variant includes the -S magnet for position sensing alongside the -B male M26x1.5 piston rod. Remember that a plain compact 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 suspended loads, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 30–70 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 SDAJ100X70-40SB FAQ
At 0.5 MPa it provides 3927 N of push and 3524.9 N of pull. At 0.7 MPa the push is 5497.8 N and pull is 4934.8 N. The theoretical maximum push is 801 kgf at 1.0 MPa.
The M27x2.0 adjuster screw mechanically shortens the extend stroke by up to 40 mm, allowing a usable range of 30-70 mm; it does not alter the force or lock mid-stroke. The included -S magnet works with AirTAC reed or electronic solid-state switches for end-position sensing.
