Airtac SDAJ50~63 Adjustable Ultra-Thin Cylinder SDAJ50X120-50SB
The AirTAC Airtac SDAJ50~63 Adjustable Ultra-Thin Cylinder SDAJ50X120-50SB is a genuine double-acting COMPACT cylinder (Ø50mm bore) whose extend end-position is set by an external M16×1.5 adjustment screw. You can dial the stroke anywhere from 70 to 120 mm on the machine — no shims, no part change.

About the Airtac SDAJ50~63 Adjustable Ultra-Thin Cylinder SDAJ50X120-50SB
The AirTAC SDAJ50X120-50SB is a compact double-acting single-rod cylinder built for on-site extend positioning. An external M16x1.5 adjuster screw lets you dial the forward stop anywhere between 70 and 120 mm without swapping shims or parts. Because the mechanism only limits travel, output remains identical to a standard 50 mm bore, delivering 981.7 N of push at 0.5 MPa.
This variant includes a built-in piston magnet for AirTAC reed or electronic switches and a male M18x1.5 rod thread. The short riveted body minimizes axial footprint where space is tight. End shock is handled by a fixed NBR bumper, which decelerates the piston but is not an adjustable air cushion.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø50 mm |
| Max stroke | 120 mm |
| Adjustable range | 70 – 120 mm |
| Adjuster thread (R) | M16×1.5 |
| Port size | PT1/4 |
| Acting type | Double acting |
|---|---|
| Rod end thread | M10×1.5 F / M18×1.5 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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 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 SDAJ50~63 Adjustable Ultra-Thin Cylinder SDAJ50X120-50SB Is Used
Machining Clamp Tuning
Dial the extend stop from 70 to 120 mm to accommodate raw stock variations without machining custom spacers.
Carton Flap Folding
Adjust the male M18x1.5 rod endpoint on-site to match different box heights during production changeovers.
Vertical Lift Stops
Safely lift 50 kg loads with a 2:1 margin while setting precise upper travel limits via the M16x1.5 screw.
Is the Airtac SDAJ50~63 Adjustable Ultra-Thin Cylinder SDAJ50X120-50SB the Right Cylinder?
When sizing this unit, compare its 981.7 N push at 0.5 MPa against adjacent bores: a 40 mm bore yields 628.3 N, while a 63 mm bore provides 1558.6 N. This model fits applications needing roughly 589 N of safe working load (about 60% of the 0.5 MPa figure) or a 50 kg vertical lift with a 2:1 safety margin.
Choose this specific configuration if your fixture requires male M18x1.5 rod threading, switch sensing via the internal magnet, and frequent changeovers. Remember that a standard cylinder drifts when air is lost or a valve centers; the bumper and mechanical stop only decelerate and set position, so add an external rod lock or pilot-operated check valve for true load holding.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 70–120 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 M16×1.5 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 SDAJ50~63 Adjustable Ultra-Thin Cylinder SDAJ50X120-50SB FAQ
At 0.5 MPa this 50 mm bore cylinder provides 981.7 N push and 824.7 N pull. At 0.7 MPa it yields 1374.4 N push and 1154.5 N pull. The theoretical maximum is 200 kgf at 1.0 MPa.
The M16x1.5 screw shortens the extend endpoint by up to 50 mm, giving a usable 70 to 120 mm range. The included S magnet works with AirTAC reed or electronic switches for position sensing.
