Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X60-40
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X60-40 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 20 to 60 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X60-40
The AirTAC SDAJ80X60-40 is a double-acting, single-rod compact cylinder featuring an external adjustable extend stop. By turning the M20x1.5 adjuster screw, you can dial the forward end-position anywhere between 20 and 60 mm directly on your 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 2513.3 N of push at 0.5 MPa.
Its short riveted body saves valuable axial mounting depth where a larger profile cylinder would never fit. End-of-stroke deceleration is handled by a fixed NBR bumper, 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.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X60-40 |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø80 mm |
| Max stroke | 60 mm |
| Adjustable range | 20 – 60 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 40 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 SDAJ80X60-40 Is Used
Press Fit Calibration
Dial the M20x1.5 screw to set a precise 35 mm extend stop for seating bearings, utilizing the 2513.3 N push force without over-traveling during tooling changeovers.
Heavy Vertical Lifts
Raise 128 kg platforms safely with a 2:1 margin at 0.5 MPa, tweaking the stop down to 20 mm when ceiling clearance or fixture heights vary on the line.
Carton Flap Folding
Adjust the extend length on the fly for different box sizes, letting the fixed NBR bumper absorb the repeated end-shock of high-speed folding arms.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X60-40 the Right Cylinder?
When sizing this model, evaluate your thrust requirements both ways: stepping down to an SDAJ63 provides 1558.6 N of push at 0.5 MPa, while stepping up to an SDAJ100 yields 3927 N. This 80 mm bore generates 2513.3 N at 0.5 MPa, translating to a safe working load of roughly 1508 N for a 2:1 safety margin, or a vertical lift capacity of about 128.1 kg. Choose this unit if your assembly process requires frequent on-machine stroke tuning between 20 and 60 mm.
Confirm your required extend window, the PT3/8 port, and the 25 mm rod diameter before ordering. Keep in mind that a plain SDAJ does not hold position if air pressure drops or the valve is centered; the fixed bumper only decelerates near the end of travel. For suspended or vertical loads that must remain fixed during air loss, integrate an external rod lock or a pilot-operated check valve. This configuration has a female M14x1.5 rod-end thread and no magnet.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 20–60 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 SDAJ80X60-40 FAQ
This 80 mm bore cylinder features a PT3/8 port and delivers 2513.3 N push / 2267.8 N pull at 0.5 MPa, 3518.6 N push / 3175 N pull at 0.7 MPa, and a theoretical maximum of 513 kgf at 1.0 MPa.
The external M20x1.5 screw shortens the extend stroke by up to 40 mm, allowing you to set the forward stop anywhere between 20 and 60 mm without altering the force. This specific SKU lacks a piston magnet; to use reed or electronic switches, you must select the -S magnet option.
