Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X65-20B
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X65-20B 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 45 to 65 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X65-20B
The AirTAC SDAJ100X65-20B is a double-acting compact cylinder featuring an external R (M27x2.0) adjuster screw that dials the extend stop between 45 and 65 mm on-site. 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 SKU uses a male-threaded M26x1.5 piston rod and a PT3/8 air port.
Designed with a short riveted body, this unit saves axial mounting depth where a larger profile cylinder will not fit. It relies on a fixed NBR bumper at each end to decelerate the stroke, which is not an adjustable air cushion. Note that this specific model lacks a piston magnet, so it cannot accept reed or electronic switches without switching to the -S variant.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X65-20B |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 65 mm |
| Adjustable range | 45 – 65 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 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 SDAJ100X65-20B Is Used
Heavy Press Fitment
Dial in the 45-65 mm extend stop on heavy press operations to precisely seat large bearings without over-traveling, utilizing the 3927 N push force at 0.5 MPa.
Automated Assembly Forming
Fine-tune the male M26x1.5 rod extension during automated assembly line changeovers, using the fixed NBR bumper to absorb the impact of high-energy forming strokes.
Vertical Lift Positioning
Adjust the extend stop on-site for vertical lifting tasks up to 200.2 kg, ensuring exact placement while relying on a pilot-operated check valve to hold the load safely.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X65-20B the Right Cylinder?
When sizing this 100 mm bore actuator, evaluate both sides with real 0.5 MPa push figures. Stepping down, the SDAJ80 provides 2513.3 N of push, making this SDAJ100X65-20B the correct upgrade when you need the full 3927 N output. Since 100 mm is the largest standard compact bore in this family, heavier loads require parallel cylinders or an external shock absorber. This model fits applications requiring on-site stroke tuning during changeovers, allowing the extend position to be fine-tuned without shims or part swaps.
Confirm the bore (100 mm), nominal stroke (65 mm), 20 mm adjustment window, PT3/8 port, and male M26x1.5 rod thread. A safe working load is roughly 2356 N, equating to a vertical lift of about 200.2 kg with a 2:1 safety margin. Remember that a plain cylinder does not hold its load if air pressure drops or the valve centers; the bumper only decelerates near the end of travel. For secure load holding without live pressure, install an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 45–65 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 SDAJ100X65-20B FAQ
This 100 mm bore double-acting 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 air port is PT3/8.
Turning the external M27x2.0 R screw shortens the extend stroke by up to 20 mm, providing a usable range of 45 to 65 mm without changing parts. This specific SKU lacks the -S magnet option, so it cannot support reed or electronic switches.
