Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X120-40B
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X120-40B 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 80 to 120 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X120-40B
The AirTAC SDAJ100X120-40B is a double-acting, single-rod compact cylinder featuring an external extend stop. Turning the R (M27x2.0) adjuster screw lets you dial the outward stroke down by up to 40 mm directly on the machine, yielding a usable extend range of 80 to 120 mm without swapping shims or parts. Because the mechanism only sets the mechanical stop position, output force remains identical to a standard SDA of this bore, providing 3927 N of push at 0.5 MPa.
This 100 mm bore unit utilizes a short riveted body to minimize axial mounting depth where a larger profile cylinder would not fit. It comes with a male-threaded piston rod (M26x1.5) for secure tooling attachment and a fixed NBR bumper at each end to decelerate the stroke. Note that this specific SKU lacks a piston magnet, so it cannot host reed or electronic switches.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X120-40B |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 120 mm |
| Adjustable range | 80 – 120 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 SDAJ100X120-40B Is Used
Heavy Press Tooling Calibration
Dial the M27x2.0 stop screw to precisely set the 80-120 mm extend position during press setup, ensuring the 3927 N thrust engages the workpiece without over-travel.
High-Capacity Diverter Arms
Adjust the outward stroke on-site to accommodate different pallet sizes on a line, using the compact riveted body to save axial space in tight transfer zones.
Vertical Lift Stops
Set mechanical end positions for heavy lifting tasks up to 200.2 kg, relying on the male M26x1.5 rod for robust load coupling while noting that an external check valve is required for load holding.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X120-40B the Right Cylinder?
When sizing this unit, evaluate both neighboring bores: the SDAJ80 delivers 2513.3 N push at 0.5 MPa, whereas this 100 mm bore yields 3927 N, giving a safe working load of roughly 2356 N (about 60 percent of the 0.5 MPa figure) and a vertical lift capacity near 200.2 kg with a 2:1 margin. Choose the 100 mm if the 80 mm lacks thrust for your heaviest tooling, but avoid oversizing if 2513.3 N suffices, as the larger body consumes more mounting space.
This model is ideal for setups requiring frequent on-machine stroke tuning during changeovers. Confirm your parameters: 100 mm bore, 120 mm max stroke, 40 mm adjust window, PT3/8 port, male M26x1.5 rod, and no magnet. Remember 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 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 80–120 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 SDAJ100X120-40B FAQ
This 100 mm bore cylinder generates 3927 N push and 3524.9 N pull at 0.5 MPa, and 5497.8 N push and 4934.8 N pull at 0.7 MPa. The theoretical maximum push force is 801 kgf at 1.0 MPa.
The external M27x2.0 screw mechanically shortens the extend stroke by up to 40 mm, allowing you to set the outward stop anywhere between 80 and 120 mm. This specific SKU has no piston magnet, so it cannot support reed or electronic switches; you would need the -S variant for sensing.
