Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X120-75
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X120-75 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 120 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X120-75
The AirTAC SDAJ100X120-75 is a double-acting, single-rod compact cylinder featuring an external adjustable extend stop. Turning the R (M27x2.0) screw lets you dial the forward end-position anywhere between 45 and 120 mm directly on your machine, eliminating the need for shims or part swaps during changeovers. 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, yielding 3927 N of push at 0.5 MPa.
Its short riveted body drastically saves axial mounting depth where a larger profile cylinder would fail to fit. End-of-travel deceleration is handled by a fixed NBR bumper at each end, which absorbs shock but is not an adjustable air cushion. Note that this specific SKU lacks a piston magnet, so it cannot host reed or electronic switches; adding an -S variant resolves sensing needs.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 120 mm |
| Adjustable range | 45 – 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 75 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 SDAJ100X120-75 Is Used
Heavy Press Tuning
Dial the 45-120 mm extend stop on a heavy press to set precise forming depth, leveraging the 3927 N push at 0.5 MPa without changing mounting hardware.
Large Fixture Changeover
Adjust the mechanical stop on-site during production line changeovers to accommodate different large part dimensions, saving axial space with its compact riveted body.
Vertical Lift Positioning
Lift loads up to 200.2 kg with a 2:1 safety margin and fine-tune the exact raise height using the M27x2.0 screw, ensuring accurate placement before the fixed NBR bumper takes the shock.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X120-75 the Right Cylinder?
When sizing this 100 mm bore actuator, evaluate your thrust limits both ways. Stepping down to an SDAJ80 drops the 0.5 MPa push force to 2513.3 N, whereas this 100 mm model provides 3927 N. Operating at the top of the standard range leaves no larger compact bore in this family, making it the maximum thrust choice here. Based on the 0.5 MPa output, a safe working load is roughly 2356 N (about 60 percent of capacity), translating to a vertical lift capability of approximately 200.2 kg with a 2:1 safety margin.
Choose this unit if your application requires on-site stroke tuning across its 45 to 120 mm window. Confirm your setup needs a PT3/8 air port, a female M18x1.5 rod-end thread, and a 32 mm piston rod. Remember that a plain SDAJ does not hold position or carry load when air is lost or the valve is centred; the fixed bumper only decelerates near the end and the R screw is a mechanical stop, not a lock. For load holding without live pressure, integrate an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 45–120 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 SDAJ100X120-75 FAQ
This 100 mm bore double-acting cylinder delivers 3927 N push and 3524.9 N pull at 0.5 MPa, increasing to 5497.8 N push and 4934.8 N pull at 0.7 MPa. The theoretical maximum push is 801 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, with a proof pressure of 1.5 MPa, and runs at speeds of 30-500 mm/s.
The external R (M27x2.0) adjuster screw shortens the extend stroke by up to 75 mm, providing a usable forward range of 45 to 120 mm. This screw sets the mechanical stop position without changing the piston area, so force remains constant. This specific SKU does not include a piston magnet for sensing; you would need the -S option to use reed or electronic switches.
