Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X85-40S
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X85-40S 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 45 to 85 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X85-40S
The AirTAC SDAJ100X85-40S is a double-acting compact cylinder featuring an external adjustable extend stop. By turning the R (M27x2.0) screw, you can dial the forward stroke anywhere between 45 and 85 mm directly on the machine. This on-site tuning eliminates shims and part changes during setup or changeover. The short riveted body saves axial mounting depth where a round-body cylinder will not fit.
Because the adjuster sets the mechanical stop rather than the piston area, force remains identical to a standard SDA of this bore. You get 3927 N of push at 0.5 MPa. The bore dictates a PT3/8 air port and a 32 mm rod, while a fixed NBR bumper decelerates the stroke end. The included -S magnet works with AirTAC reed or electronic switches.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X85-40S |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 85 mm |
| Adjustable range | 45 – 85 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 SDAJ100X85-40S Is Used
Heavy Press Fitment
Dial the 45-85 mm extend stop to set precise insertion depth for heavy bearings, leveraging 3927 N of thrust without swapping components.
Tooling Changeover
Adjust the mechanical stop on-site during production line changeovers to accommodate different jig heights quickly.
Vertical Lift Stations
Lift loads up to 200.2 kg with a 2:1 safety margin, tweaking the downward travel limit to prevent hard crashes into fixed structures.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X85-40S the Right Cylinder?
When sizing this 100 mm bore actuator, evaluate your neighbours: an SDAJ80 yields 2513.3 N push at 0.5 MPa, whereas this SDAJ100 hits 3927 N. This yields a safe working load around 2356 N (about 60% of the 0.5 MPa figure) or a vertical lift of roughly 200.2 kg with a 2:1 margin. Choose the 100 mm if the 80 mm lacks thrust, but avoid oversizing if 2513.3 N suffices.
Operators who need frequent trial positioning or changeover benefit from the 40 mm adjust window. Confirm your requirements for bore, 85 mm stroke, 40 mm window, PT3/8 port, female M18x1.5 rod thread, and the -S magnet. Remember that a plain cylinder drifts on air loss; for load holding without live pressure, install an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 45–85 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 SDAJ100X85-40S FAQ
This 100 mm bore cylinder provides 3927 N push and 3524.9 N pull at 0.5 MPa. At 0.7 MPa it yields 5497.8 N push and 4934.8 N pull. The theoretical maximum push is 801 kgf at 1.0 MPa.
The M27x2.0 adjuster screw shortens the extend stop by up to 40 mm, giving a usable 45-85 mm range. It sets the stop, not the force. The built-in -S magnet enables position sensing with AirTAC reed or electronic switches.
