Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X45-40SB
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X45-40SB 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 5 to 45 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X45-40SB
The AirTAC SDAJ80X45-40SB is a double-acting, single-rod compact cylinder featuring an external M20x1.5 adjustment screw that dials the extend stop directly on your machine between 5 and 45 mm. Its short riveted body saves axial mounting depth where a round-body or profile cylinder will not fit. The integrated piston magnet supports AirTAC reed or electronic switches for precise end-position sensing.
Turning the R thread sets the mechanical stop position without shims, but force remains identical to a standard SDA of this 80 mm bore, delivering 2513.3 N push at 0.5 MPa. The unit uses a fixed NBR bumper to decelerate the stroke end rather than an adjustable air cushion. This specific configuration includes a male M22x1.5 piston rod thread and a PT3/8 air port.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X45-40SB |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø80 mm |
| Max stroke | 45 mm |
| Adjustable range | 5 – 45 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 SDAJ80X45-40SB Is Used
Heavy Press Fitments
Dial the 5-45 mm extend stop to trial-fit bearings precisely, leveraging the 2513.3 N push at 0.5 MPa without over-stressing the workpiece.
Vertical Lift Stations
Hoist payloads up to 128.1 kg safely with a 2:1 margin, using the male M22x1.5 rod for robust tooling attachment in elevation rigs.
Changeover Assemblies
Quickly reposition the mechanical stop for different product heights on a packaging line, avoiding part swaps while maintaining full retract motion.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X45-40SB the Right Cylinder?
When sizing this unit, stepping down to an SDAJ63 yields 1558.6 N push at 0.5 MPa, while stepping up to an SDAJ100 provides 3927 N. This 80 mm bore provides a safe working load of roughly 1508 N (about 60% of its 0.5 MPa rating), translating to a vertical lift capacity of approximately 128.1 kg with a 2:1 safety margin. Choose this model if your fixture requires on-site stroke tuning during frequent changeovers.
Confirm the 80 mm bore, 45 mm maximum stroke, 40 mm adjust window, PT3/8 port, built-in magnet (-S), and male M22x1.5 rod thread (-B) match your mounting interface. Note that a plain cylinder does not hold its load on air loss or when the valve is centred; the piston drifts and the fixed bumper only decelerates near the end. 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 5–45 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 SDAJ80X45-40SB FAQ
At 0.5 MPa it provides 2513.3 N push and 2267.8 N pull. At 0.7 MPa it yields 3518.6 N push and 3175 N pull. The theoretical maximum push is 513 kgf at 1.0 MPa. Operating pressure spans 0.15-1.0 MPa, proof pressure is 1.5 MPa, and speed ranges 30-500 mm/s.
The M20x1.5 R screw shortens the extend stroke by up to 40 mm, allowing usable positions from 5 to 45 mm without changing parts; retract remains full. The built-in -S magnet works with AirTAC reed or electronic switches, and the fixed NBR bumper decelerates the stroke end but does not lock the load.
