Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X50-50
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X50-50 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 0 to 50 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X50-50
The AirTAC SDAJ80X50-50 is a double-acting, single-rod compact cylinder featuring an external M20x1.5 adjustment screw that dials the extend stop from 0 to 50 mm directly on your machinery. Because the adjuster dictates the mechanical end position 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. The short riveted body drastically cuts axial mounting depth, fitting into tight footprints where larger profile cylinders cannot.
This 80 mm bore unit relies on a fixed NBR bumper at each end to decelerate the stroke, meaning it is not an adjustable air cushion or a mid-stroke lock. Operating at speeds of 30-500 mm/s, it provides a safe working load of roughly 1508 N (about 60 percent of the 0.5 MPa push figure) and can vertically lift approximately 128.1 kg with a 2:1 safety margin.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X50-50 |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø80 mm |
| Max stroke | 50 mm |
| Adjustable range | 0 – 50 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 SDAJ80X50-50 Is Used
Heavy Press Dial-In
Ideal for high-force pressing stations needing exact bottom-out depth, letting operators turn the M20x1.5 screw to set the 0-50 mm extend stop without swapping parts.
Large Package Diverting
Provides robust 2513.3 N push at 0.5 MPa to deflect heavy pallets, with on-machine adjustability to accommodate varying package sizes on the fly.
Vertical Lift Stops
Handles vertical lifts up to roughly 128.1 kg with a 2:1 margin, allowing technicians to tune the extend position precisely for multi-tier elevation tasks.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X50-50 the Right Cylinder?
When sizing this model, compare its 2513.3 N push at 0.5 MPa against neighbouring bores: stepping down to the SDAJ63 yields 1558.6 N, while stepping up to the SDAJ100 provides 3927 N. Choose this 80 mm variant when your setup demands high force but requires frequent on-site stroke tuning to dial in exact end positions. Confirm your specifications match an 80 mm bore, a 50 mm maximum stroke, a 50 mm adjustment window, and a PT3/8 air port.
This base SKU lacks a piston magnet and cannot support reed or electronic switches; select the -S option if you require position sensing. Remember that a plain cylinder does not hold its load upon air loss or valve centering, as the fixed bumper only decelerates near the stroke end. For suspended or vertical loads, integrate an external rod lock or a pilot-operated check valve to prevent drifting.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 0–50 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 SDAJ80X50-50 FAQ
This 80 mm bore cylinder generates 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.
Turning the external R (M20x1.5) screw mechanically shortens the extend stop by up to 50 mm, giving a usable extend range of 0-50 mm. It sets the end position without altering the force, and it is not a mid-stroke lock.
