Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-40SB
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-40SB 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 35 to 75 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-40SB
The SDAJ100X75-40SB is a double-acting compact cylinder featuring an external R (M27x2.0) adjustment screw that dials the extend stop from 35 to 75 mm directly on your machine. Because the adjuster sets the mechanical stop rather than altering the piston area, output force remains identical to a standard 100 mm bore SDA, delivering 3927 N of push at 0.5 MPa.
This variant includes a built-in piston magnet (-S) for AirTAC reed or electronic switches and a male M26x1.5 threaded rod end (-B). Its short riveted body conserves axial mounting depth where larger profile cylinders cannot fit, while a fixed NBR bumper at each end absorbs end-of-stroke shock without acting as a lock.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 75 mm |
| Adjustable range | 35 – 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 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 SDAJ100X75-40SB Is Used
Heavy Press Tuning
Dial the 35 to 75 mm extend stop during press changeovers to set precise forming depth without swapping mechanical shims.
Vertical Lift Positioning
Lift loads up to 200.2 kg safely, using the M27x2.0 screw to fine-tune the exact raise height on the assembly line.
Large Crate Sealing
Adjust the extend endpoint on the fly to accommodate varying crate heights, relying on the 3927 N push force to secure heavy flaps.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-40SB the Right Cylinder?
When sizing this unit, evaluate both directions: dropping down to an SDAJ80 yields 2513.3 N of push at 0.5 MPa, whereas this 100 mm bore provides 3927 N. A practical safe working load is roughly 2356 N, which equates to a vertical lift capacity of about 200.2 kg when applying a 2:1 safety margin. Choose this model if your setup requires frequent on-machine stroke tuning between 35 and 75 mm.
Remember that a plain cylinder does not hold its load if air pressure drops or the valve is centred—the piston will drift. For load holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve. Confirm your requirements for the PT3/8 port, the male M26x1.5 rod thread, and the integrated magnet before finalizing.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 35–75 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 SDAJ100X75-40SB FAQ
At 0.5 MPa it provides 3927 N push and 3524.9 N pull. At 0.7 MPa it provides 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 endpoint within a 35 to 75 mm window without changing the force. The built-in magnet allows tracking via AirTAC reed or electronic switches, while the fixed NBR bumper decelerates the stroke end but does not lock the load.
