Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X80-50SB
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X80-50SB 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 30 to 80 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X80-50SB
The SDAJ100X80-50SB is a double-acting, single-rod compact cylinder featuring an external R (M27x2.0) adjuster screw. This mechanism lets you dial the extend stop down from the 80 mm maximum to 30 mm directly on your equipment, eliminating the need for shims or part swaps during changeovers. Force remains identical to a standard SDA of this bore, delivering 3927 N of push at 0.5 MPa.
Built with a space-saving riveted body, this unit fits where longer profile or round-body cylinders cannot. It includes a built-in piston magnet (-S) for AirTAC reed or electronic switches, and a male-thread piston rod (-B, M26x1.5) for secure tooling attachment. End-of-travel deceleration relies on a fixed NBR bumper, not an adjustable air cushion.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 80 mm |
| Adjustable range | 30 – 80 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 50 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 SDAJ100X80-50SB Is Used
Heavy Press Fit Tooling
Dial the M27x2.0 adjuster to set precise 30-80 mm extend stops for pressing bearings, leveraging the 3927 N push force without swapping physical spacers.
Vertical Lift Stations
Hoist 200 kg payloads using the male M26x1.5 rod end, relying on the compact riveted body to save vertical mounting space in tight lift assemblies.
Multi-Product Changeover Lines
Quickly reposition the extend stop on-site for different product heights, using the integrated magnet to confirm end-of-travel via reed or electronic switches.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X80-50SB the Right Cylinder?
When sizing this 100 mm bore actuator, evaluate your force margins carefully. Stepping down to an SDAJ80 yields 2513.3 N of push at 0.5 MPa, which may be insufficient for heavy tooling, whereas this 100 mm bore provides a safe working load of roughly 2356 N (about 60% of its 0.5 MPa capacity) and can manage a vertical lift of approximately 200.2 kg with a 2:1 safety margin. Confirm your required extend window falls between 30 and 80 mm, and note the PT3/8 porting.
This configuration includes the -S magnet for position sensing and the -B male M26x1.5 rod end. Remember that the fixed NBR bumper only decelerates the stroke end; it does not act as a lock. If your application requires holding a load during air loss or valve centering, you must integrate an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 30–80 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 SDAJ100X80-50SB FAQ
At 0.5 MPa, this 100 mm bore cylinder provides 3927 N of push force and 3524.9 N of pull force. At 0.7 MPa, push increases to 5497.8 N and pull to 4934.8 N. The theoretical maximum push is 801 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, with a proof pressure of 1.5 MPa.
The R (M27x2.0) screw mechanically shortens the extend stroke by up to 50 mm, allowing you to set the end position anywhere between 30 mm and 80 mm without changing parts; retract remains full. The included -S magnet works with AirTAC reed or electronic solid-state switches mounted in the body grooves for position confirmation.
