Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X40-20
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X40-20 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 20 to 40 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X40-20
The AirTAC SDAJ100X40-20 is a compact double-acting single-rod cylinder featuring an external extend stop. A front R (M27x2.0) adjustment screw lets you dial the extend position down from the 40mm maximum to a 20mm minimum directly on the machine, eliminating the need for shims or part swaps. Because the adjuster sets the mechanical stop rather than the piston area, output force remains identical to a standard SDA of this bore, delivering 3927N push at 0.5MPa.
Built with a short riveted body, this unit saves axial mounting depth in tight spaces where larger profile or round-body cylinders cannot 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 support reed or electronic switches without upgrading to the -S variant.
Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X40-20 Technical Specifications
| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X40-20 |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 40 mm |
| Adjustable range | 20 – 40 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 SDAJ100X40-20 Is Used
Heavy Press Fit Tuning
Dial in the exact 20-40mm extend reach during initial tooling commissioning to prevent over-travel on high-force press fits, utilizing the full 3927N push at 0.5MPa.
Product Divertor Setup
Adjust the mechanical stop on-site without changing parts when product widths change, ensuring the 32mm rod pushes heavy pallets accurately without bottoming out.
Vertical Lift Positioning
Fine-tune the lift height for a 200.2kg payload with a 2:1 safety margin, locking the extend stop at the precise 35mm mark needed for multi-tier stacking.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X40-20 the Right Cylinder?
When sizing this 100mm bore actuator, compare its 3927N push at 0.5MPa against the neighboring SDAJ80, which provides 2513.3N at the same pressure. Stepping up to this 100mm unit is necessary when your payload exceeds the 80mm capacity, offering a safe working load of roughly 2356N (about 60% of the 0.5MPa figure) or a vertical lift of approximately 200.2kg with a 2:1 margin. If your application requires even more force, this is the largest standard bore in the SDA family.
This model is specified for setup-heavy lines needing frequent trial positioning. Confirm your parameters: 100mm bore, 40mm maximum stroke, 20mm adjust window, PT3/8 port, female M18x1.5 rod-end thread, and no magnet. Remember that a plain cylinder does not hold position or load when air is lost or the valve is centered; the fixed bumper only decelerates near the end. For load holding without live pressure, install an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 20–40 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 SDAJ100X40-20 FAQ
This 100mm bore double-acting cylinder delivers 3927N push and 3524.9N pull at 0.5MPa, 5497.8N push and 4934.8N pull at 0.7MPa, with a theoretical maximum of 801kgf at 1.0MPa. The air port is PT3/8.
The external M27x2.0 screw mechanically shortens the extend stroke from 40mm down to 20mm without changing the output force. It is a stop, not a lock; the cylinder cannot hold a load if air pressure is lost, requiring an external rod lock for fail-safe holding.
