About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X55-50B
The AirTAC SDAJ80X55-50B is a double-acting compact cylinder featuring an external M20x1.5 adjuster screw that dials the extend stop from 5 to 55 mm directly on your machine. Because the mechanism sets the mechanical stop rather than altering the piston area, output force remains identical to a standard 80 mm bore SDA, delivering 2513.3 N of push at 0.5 MPa.
Its short riveted body drastically reduces axial mounting depth compared to round-body alternatives, while the fixed NBR bumper decelerates the stroke end without requiring adjustable air cushions. This specific SKU includes a male M22x1.5 piston rod and lacks a piston magnet, meaning it cannot host reed or electronic switches without upgrading to the -S variant.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X55-50B |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø80 mm |
| Max stroke | 55 mm |
| Adjustable range | 5 – 55 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 50 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 SDAJ80X55-50B Is Used
Press Fit Depth Tuning
Dial in the 5 to 55 mm extend stop on the fly to set precise bearing press depths without swapping shims, leveraging the 2513.3 N push force for reliable seating.
Variable Flap Folding
Adjust the mechanical stop on-site to accommodate different carton heights, using the male M22x1.5 rod to drive folding arms through rapid changeovers.
Heavy Vertical Lifts
Lift loads up to 128.1 kg with a 2:1 safety margin, tweaking the extend endpoint to clear varying pallet heights before initiating the descent.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X55-50B the Right Cylinder?
When sizing this 80 mm bore actuator, evaluate both neighbours: stepping down to the SDAJ63 yields 1558.6 N push at 0.5 MPa, whereas the larger SDAJ100 provides 3927 N. The SDAJ80X55-50B fits applications requiring roughly 2513.3 N, translating to a safe working load around 1508 N or a vertical lift capacity near 128.1 kg with a 2:1 margin. Choose this model when you need frequent on-site stroke tuning to accommodate varying material thicknesses or trial positioning.
Confirm the 80 mm bore, 55 mm maximum stroke, 50 mm adjustment window, and PT3/8 air port suit your manifold. Note the male M22x1.5 rod thread for your mounting clevis. Crucially, a plain SDAJ does not hold position or load when air is lost or the valve is centred; the fixed bumper only decelerates near the end of travel. 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 5–55 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 SDAJ80X55-50B FAQ
This 80 mm bore double-acting cylinder generates 2513.3 N push and 2267.8 N pull at 0.5 MPa, or 3518.6 N push and 3175 N pull at 0.7 MPa. The theoretical maximum push is 513 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa at speeds of 30-500 mm/s.
Turning the external M20x1.5 screw shortens the extend endpoint anywhere between 5 and 55 mm without changing the output force. This mechanism is strictly a mechanical stop, not a mid-stroke lock; the cylinder cannot hold a load if air pressure is lost, and the fixed NBR bumper only decelerates the stroke end.
