About the Airtac SCJ50 Standard Cylinder SCJ50X160-10
The SCJ50X160-10 is a double-acting, single-rod pneumatic cylinder with a field-adjustable stroke end, providing a 10 mm adjustment range via a rear-cap screw. With a 50 mm bore and 20 mm rod, it delivers a push force of 982 N at 0.5 MPa, scaling up to 1767 N at the maximum operating pressure of 0.9 MPa, making it a strong mid-range actuator for tasks requiring fine positional tuning.
This model has a 160 mm nominal stroke, well within the 1200 mm maximum standard stroke for the 50 mm bore. The PT1/4 port, M16x1.5 rod thread, and 21 mm air cushion are standard for this size. The body length is 194 mm, and the rear screw allows operators to shorten the stroke end to precisely dial in a stopping position without replacing the cylinder or adding external hard stops.
Airtac SCJ50 Standard Cylinder SCJ50X160-10 Technical Specifications
| Model | Airtac SCJ50 Standard Cylinder SCJ50X160-10 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø50 mm |
| Nominal stroke | 160 mm |
| Stroke adjustment | Up to 10 mm (rear adjusting screw) |
| Acting type | Double acting (single rod) |
| Port size | PT1/4 |
| Rod thread | M16×1.5 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Adjustable, 21 mm |
| Max stroke | Up to 1200 mm |
Specifications follow the official AirTAC SCJ (adjustable-stroke) datasheet. The rear adjusting screw sets the stroke end position; force is the same as the equivalent single-rod SC bore. Confirm against the product label before installation. Thread options: PT (standard) / G.
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 | |
SCJ is single-rod, so force matches the equivalent SC bore: push uses the full bore area, pull subtracts the rod area. Actual usable force is lower than theoretical due to friction and back-pressure; size with a safety margin.

Where the Airtac SCJ50 Standard Cylinder SCJ50X160-10 Is Used
End-Stop Calibration
Fine-tune the retract stroke end position during machine commissioning to compensate for tolerance stack-up in a clamping fixture, using the 10 mm rear adjustment screw.
Product Gate Adjustment
Adjust the opening stroke of a diverter gate on a conveyor line to match different package heights without reprogramming the controller or changing the cylinder.
Wear Compensation
Take up mechanical wear in a pressing or forming operation by slightly shortening the stroke end, maintaining consistent final position over the cylinder's service life.
Is the Airtac SCJ50 Standard Cylinder SCJ50X160-10 the Right Cylinder?
Step up to a 63 mm bore if the 982 N push force at 0.5 MPa is marginal, as the SCJ63 series offers 1559 N at the same pressure. For applications needing a fixed, non-adjustable stroke, the standard SC50X160 is a lighter and more cost-effective alternative. The adjustable stroke is ideal for commissioning and process fine-tuning, but if the load introduces significant side forces, consider an external guide rail.
This SCJ50X160-10 is a direct replacement for another AirTAC SCJ50 cylinder with a 160 mm nominal stroke, 10 mm adjustment range, PT ports, and basic mounting. Ensure the replacement matches the port thread, magnet option, and any mounting accessories like FA or LB brackets.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-10)
- ✓ Required force at your working pressure
- ✓ Port/thread type (PT/NPT/G)
- ✓ 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 Set the rear adjusting screw, then lock it before running.
- check Adjust end cushion screws for smooth stops.
- check Use SCJ mounting accessory (FA / LB / TC / TCM1).
- check Installation by qualified personnel per AirTAC docs.
Airtac SCJ50 Standard Cylinder SCJ50X160-10 FAQ
At 0.5 MPa, the push force is 982 N and the pull force is 825 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1767 N. The pull force is lower due to the area of the 20 mm piston rod.
Yes, it can replace an SC50X160 if you need the 10 mm stroke-end adjustability. The mounting footprint and port locations are identical, but the SCJ body is slightly longer to accommodate the rear adjusting mechanism. Ensure the port thread (PT) and mounting style match.
