Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X50-20
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X50-20 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 50 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X50-20
The AirTAC SDAJ80X50-20 is a double-acting compact cylinder featuring an external adjustable extend stop. An M20x1.5 adjuster screw lets you dial the extend end-position anywhere between 30 and 50 mm directly on the machine, eliminating the need for shims or part swaps during changeovers. Retract travel remains full length. Because the mechanism only sets the mechanical stop rather than altering the piston area, output force equals a standard SDA of this bore, yielding 2513.3 N of push at 0.5 MPa.
Its short riveted body drastically cuts axial mounting depth where a larger round-body unit will not fit. End-of-stroke energy is managed by a fixed NBR bumper that decelerates the piston, though it is not an adjustable air cushion. Operating speed spans 30-500 mm/s, and the PT3/8 port matches the 80 mm bore specification.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø80 mm |
| Max stroke | 50 mm |
| Adjustable range | 30 – 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 20 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 SDAJ80X50-20 Is Used
Press Fit Depth Tuning
Dial in the exact 30-50 mm insertion depth for heavy bearing presses on the factory floor without disassembling the tooling.
Heavy Vertical Lifting
Lift loads up to 128.1 kg with a 2:1 safety margin, tweaking the extend stop to clear varying pallet heights on the fly.
Changeover Adjustment
Shorten the extend stroke by up to 20 mm during product family changeovers to accommodate different workpiece widths instantly.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X50-20 the Right Cylinder?
When sizing this 80 mm bore actuator, compare it both ways: stepping down to an SDAJ63 provides 1558.6 N push at 0.5 MPa, while stepping up to an SDAJ100 yields 3927 N. This SDAJ80X50-20 sits comfortably in the middle at 2513.3 N, offering a safe working load of roughly 1508 N (about 60 percent of the 0.5 MPa figure) and a vertical lift capacity near 128.1 kg with a 2:1 margin.
Choose this specific model if your fixture requires frequent on-site stroke tuning within the 30-50 mm window. It lacks a piston magnet, so position sensing is not possible on this SKU; add the -S option for reed or electronic switches. Note that a plain cylinder does not hold position on air loss or valve centring—the fixed bumper only decelerates near the end. For secure load holding without live pressure, integrate an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 30–50 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 SDAJ80X50-20 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.
Turning the M20x1.5 external screw mechanically shortens the extend end-position from the 50 mm maximum down to 30 mm. It acts purely as a physical stop and does not alter the output force or lock the piston mid-stroke.
