Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X130-20B
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X130-20B 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 110 to 130 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X130-20B
The AirTAC SDAJ100X130-20B is a double-acting, single-rod compact cylinder featuring an external adjustable extend stop. By turning the R (M27x2.0) screw, you shorten the forward stroke on-site across a 110-130 mm window, eliminating the need for shims or part swaps during setup. Because the adjuster only sets the mechanical stop position rather than altering the piston area, output force remains identical to a standard SDA of this bore, delivering 3927 N push at 0.5 MPa.
This 100 mm bore unit utilizes a short riveted body to save axial mounting depth in tight machinery layouts. It features a male-threaded piston rod (M26x1.5) for direct load mounting, a PT3/8 air port, and a fixed NBR bumper at each end to decelerate the stroke. This SKU does not include a piston magnet, so it cannot host reed or electronic switches; for load holding without live air pressure, an external rod lock or pilot-operated check valve is required.

| 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 20 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 SDAJ100X130-20B Is Used
Heavy Press Fitment
Dial in the exact 110-130 mm forward stop for heavy-duty press fits without changing hardware, leveraging 3927 N of thrust at 0.5 MPa.
Large Mold Changeover
Quickly readjust the extend position during large mold or fixture changeovers on massive production lines to minimize downtime.
Vertical Lift Testing
Trial vertical lift positioning for loads up to 200.2 kg with a 2:1 safety margin, tweaking the mechanical stop to find the perfect endpoint.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X130-20B the Right Cylinder?
Choosing this 100 mm bore provides massive thrust, pushing 3927 N at 0.5 MPa, while sizing down to an SDAJ80 yields 2513.3 N under the same pressure. Engineers should verify their force margins, noting a safe working load around 2356 N (about 60% of the 0.5 MPa figure) or a vertical lift capacity near 200.2 kg with a 2:1 safety margin. If your application requires less force, the 80 mm option saves space; if you need maximum power, this is the largest standard compact frame available.
This specific configuration includes a 130 mm stroke with a 20 mm adjustment window, a male M26x1.5 rod thread, and no magnet (non-sensing). The on-machine tuning is ideal for heavy fixtures requiring trial positioning. Remember that the fixed NBR bumper only decelerates the end of travel and is not a brake; if the air supply drops, the cylinder will drift unless you install an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 110–130 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 SDAJ100X130-20B FAQ
At 0.5 MPa, it provides 3927 N push and 3524.9 N pull. 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.
The R (M27x2.0) screw mechanically limits the extend stroke, allowing you to set the forward endpoint anywhere between 110 and 130 mm. This adjustment changes the stop position only and does not alter the cylinder's output force.
