About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-20B
The AirTAC SDAJ100X75-20B is a double-acting, single-rod compact cylinder featuring an external adjustable extend stop. By turning the R (M27x2.0) screw, you can dial the extend stroke on-site between 55 and 75 mm without shims or part changes. Force remains identical to a standard SDA of this bore, delivering 3927 N of push at 0.5 MPa, because the adjuster sets the mechanical stop rather than altering the piston area.
Designed to save axial mounting depth where larger profile cylinders cannot fit, this riveted-body unit operates at 30-500 mm/s. It features a male M26x1.5 piston rod thread and a PT3/8 air port. End-of-travel deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion. This specific SKU lacks a piston magnet, so it cannot support magnetic sensing.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 75 mm |
| Adjustable range | 55 – 75 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 20 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 SDAJ100X75-20B Is Used
Heavy Press Fitments
Dial the 55-75 mm extend stop to set precise insertion depth for heavy bearings, leveraging 3927 N of push at 0.5 MPa without part changes.
Large Mold Changeover
Quickly reposition the male M26x1.5 rod end for different tooling heights on a production line, saving axial space in tight machine frames.
Vertical Lift Dampening
Lift loads up to 200.2 kg with a 2:1 safety margin, relying on the fixed NBR bumper to decelerate the stroke end in vertical material handling.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-20B the Right Cylinder?
When sizing this 100 mm bore actuator, evaluate your neighbors: the SDAJ80 provides 2513.3 N push at 0.5 MPa, while this SDAJ100 offers 3927 N. This makes the 100 mm ideal if the 80 mm stalls under heavy resistance. Based on the 0.5 MPa figure, a safe working load is roughly 2356 N (about 60 percent of capacity), allowing a vertical lift of approximately 200.2 kg with a 2:1 margin. Choose this model if your setup requires frequent on-site stroke tuning between 55 and 75 mm.
Confirm the 100 mm bore, 75 mm maximum stroke, 20 mm adjustment window, and PT3/8 port suit your manifold. This variant includes a male M26x1.5 rod end and no magnet. Note that a plain cylinder does not hold a load if air pressure drops or the valve centers; the piston drifts. For load holding without live pressure, install an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 55–75 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 SDAJ100X75-20B FAQ
This 100 mm bore cylinder provides 3927 N push and 3524.9 N pull at 0.5 MPa. At 0.7 MPa, push is 5497.8 N and pull is 4934.8 N. The theoretical maximum push is 801 kgf at 1.0 MPa.
The R (M27x2.0) screw mechanically shortens the extend stroke from the 75 mm maximum down to 55 mm. It sets the physical stop position and does not alter force. This SKU lacks the -S magnet, so it cannot accept reed or electronic switches.
