Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X40-10B
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X40-10B is a genuine double-acting COMPACT cylinder (Ø80mm bore) whose extend end-position is set by an external M20×1.5 adjustment screw. You can dial the stroke anywhere from 30 to 40 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X40-10B
The AirTAC SDAJ80X40-10B is a compact double-acting single-rod cylinder built for tight axial mounting spaces where round-body alternatives fail to fit. It features a short riveted body and an external M20x1.5 adjuster screw that lets you dial the extend stop down from 40 mm to 30 mm directly on your machine without swapping parts. Because the screw sets the mechanical stop rather than altering the piston area, output force remains identical to a standard SDA of this bore, delivering 2513.3 N of push at 0.5 MPa.
This specific SKU includes a male M22x1.5 piston rod thread for straightforward tool mounting and uses a PT3/8 air port. End-of-travel deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion. Note that this base configuration lacks a piston magnet, so it cannot host reed or electronic switches without upgrading to the -S variant.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X40-10B |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø80 mm |
| Max stroke | 40 mm |
| Adjustable range | 30 – 40 mm |
| Adjuster thread (R) | M20×1.5 |
| Port size | PT3/8 |
| Acting type | Double acting |
|---|---|
| Rod end thread | M14×1.5 F / M22×1.5 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 10 mm. Force is unchanged from a standard SDA of the same bore. Specifications follow the official AirTAC SDAJ datasheet.
Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 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 SDAJ80X40-10B Is Used
Press Fit Dial-In
Ideal for press operations needing exact seating depth; turn the M20x1.5 screw to fine-tune the extend stop within the 30-40 mm window during tooling setup without changing shims.
Heavy Vertical Lift
Handles vertical lifting tasks up to 128.1 kg with a 2:1 safety margin, providing 2513.3 N of thrust while the compact riveted body minimizes overhead mounting depth.
Changeover Positioning
Perfect for production lines with frequent format changes, allowing operators to quickly shorten the extend stroke by up to 10 mm on the machine floor to adapt to new part heights.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X40-10B the Right Cylinder?
When sizing this unit, compare its 2513.3 N push at 0.5 MPa against adjacent bores: the SDAJ63 provides 1558.6 N, while the SDAJ100 offers 3927 N. Based on the 0.5 MPa figure, a safe working load is roughly 1508 N (about 60 percent of capacity), translating to a vertical lift capability of approximately 128.1 kg with a 2:1 safety margin. Choose this 80 mm bore if your changeover process requires precise on-site extend tuning between 30 and 40 mm. Confirm your machine accepts the PT3/8 port, the male M22x1.5 rod end, and the 10 mm adjustment window. If your application must hold a vertical load during air loss or valve centering, be aware the NBR bumper only decelerates near the end of travel and the R screw is a mechanical stop, not a brake. You will need an external rod lock or pilot-operated check valve for secure load holding.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 30–40 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 M20×1.5 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 SDAJ80X40-10B FAQ
This 80 mm bore double-acting cylinder delivers 2513.3 N push and 2267.8 N pull at 0.5 MPa, 3518.6 N push and 3175 N pull at 0.7 MPa, with a theoretical maximum of 513 kgf at 1.0 MPa. The air port is PT3/8.
The external M20x1.5 screw mechanically shortens the extend stroke from the 40 mm maximum down to 30 mm without affecting the 2513.3 N force. This specific -B SKU lacks a piston magnet, so it cannot accept reed or electronic switches; you must select the -S option for sensing capabilities.
