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

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X80-30
The AirTAC SDAJ100X80-30 is a double-acting compact cylinder featuring an external adjustable extend stop. Turning the R (M27x2.0) screw lets you dial the outward stroke down from the 80 mm maximum to 50 mm directly on the machine, eliminating the need for shims or part swaps during setup. Retract travel remains full length.
Because the adjuster sets the mechanical stop rather than altering the piston area, output force equals a standard SDA of this bore, delivering 3927 N push at 0.5 MPa. The short riveted body saves axial mounting depth where a larger profile cylinder will not fit. End shock is handled by a fixed NBR bumper, which decelerates the stroke but is not an adjustable air cushion.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X80-30 |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 80 mm |
| Adjustable range | 50 – 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 30 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 SDAJ100X80-30 Is Used
Press Fit Tuning
Dial the M27x2.0 screw to set exact 50-80 mm extend stops for seating heavy bearings, leveraging 3927 N of push force without overshooting.
Heavy Forming Lines
Adjust the outward stroke on-site for different material thicknesses, using the compact riveted body to save axial depth in tight machinery.
Vertical Lift Jigs
Lift loads up to 200.2 kg with a 2:1 safety margin, fine-tuning the extend position to clear overhead obstructions during changeovers.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X80-30 the Right Cylinder?
When sizing this 100 mm bore unit, consider the SDAJ80 as the next step down, providing 2513.3 N push at 0.5 MPa. The SDAJ100X80-30 sits at the top of the range, yielding a safe working load of roughly 2356 N (about 60 percent of its 3927 N rating) and a vertical lift capacity of approximately 200.2 kg with a 2:1 margin.
This model is built for heavy setups requiring frequent changeovers or trial positioning. It lacks a piston magnet, so it cannot host reed or electronic switches; choose the -S variant if sensing is required. Note that a plain cylinder does not hold its load on air loss or valve centring—the piston drifts and the fixed bumper only decelerates near the end. For secure load holding without live pressure, install an external rod lock or pilot-operated check valve. Confirm your bore, stroke, window, PT3/8 port, and female M18x1.5 rod thread.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 50–80 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 SDAJ100X80-30 FAQ
This 100 mm bore cylinder delivers 3927 N push and 3524.9 N pull at 0.5 MPa, 5497.8 N push and 4934.8 N pull at 0.7 MPa, with a theoretical maximum of 801 kgf at 1.0 MPa.
The external R (M27x2.0) screw acts as a mechanical stop, allowing you to shorten the extend travel anywhere between 50 and 80 mm. It sets the end position without changing the force, and it is not a mid-stroke lock.
