About the Airtac SCJ50 Standard Cylinder SCJ50X110-50
The SCJ50X110-50 is a double-acting, single-rod pneumatic cylinder with a 50 mm bore and a nominal stroke of 110 mm. Its defining feature is a rear-cap adjusting screw that provides a 50 mm adjustable range, allowing the effective stroke end position to be fine-tuned on the machine without replacing the cylinder. This model delivers 982 N of push force and 825 N of pull force at 0.5 MPa, using a 20 mm diameter piston rod with M16x1.5 male threads.
Built on a durable tie-rod construction, the SCJ50X110-50 has a body length of 194 mm and features an adjustable air cushion for smooth deceleration. The standard PT1/4 port and TPU seals suit a wide range of general industrial applications, with an operating pressure range of 0.15 to 1.0 MPa. This cylinder is ideal for applications requiring frequent stroke adjustments, such as commissioning new tooling or accommodating different product sizes on a packaging line.
Airtac SCJ50 Standard Cylinder SCJ50X110-50 Technical Specifications
| Model | Airtac SCJ50 Standard Cylinder SCJ50X110-50 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø50 mm |
| Nominal stroke | 110 mm |
| Stroke adjustment | Up to 50 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 SCJ50X110-50 Is Used
Commissioning & Setup
The 50 mm adjustment range is invaluable during machine commissioning, allowing engineers to precisely dial in the optimal stroke end position for a new process without needing to stock multiple fixed-stroke cylinders.
Product Changeovers
On a packaging line, the stroke can be quickly re-adjusted to accommodate a new box or product size. The 982 N push force at 0.5 MPa is sufficient for many sorting and diverting gate applications.
Wear Compensation
In clamping or pressing fixtures, the adjustable screw allows operators to take up for pad wear or material thickness variations over time, maintaining consistent clamping force without shims or complex stops.
Is the Airtac SCJ50 Standard Cylinder SCJ50X110-50 the Right Cylinder?
Select the SCJ50X110-50 when your application requires a robust, mid-range force actuator with the flexibility to adjust the stroke end position by up to 50 mm in the field. This model is a strong choice for tasks needing around 1000 N of push force. If your load requires more force, consider stepping up to the 63 mm bore SCJ63 series, which provides 1559 N of push force at the same 0.5 MPa pressure. For applications where the stroke is fixed and will never need adjustment, the standard SC50 series offers a more economical solution.
For replacement, match this cylinder with another AirTAC SCJ adjustable-stroke model with a 50 mm bore, a 110 mm nominal stroke, and a 50 mm adjustment range. Ensure the replacement has the same PT port thread and basic mounting configuration. If you need to add position sensing, the SCJ50X110-50-S variant includes a built-in magnet for use with CMSG/DMSG sensors.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-50)
- ✓ 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 SCJ50X110-50 FAQ
The theoretical push force at 0.5 MPa is 982 N, and the pull force is 825 N. At the maximum operating pressure of 1.0 MPa, the push force increases to 1767 N. Always consider the pull force value for retraction tasks, as it is lower due to the area of the 20 mm piston rod.
It can fit in the same space if the longer body length (194 mm) is accommodated. The SCJ50X110-50 is a direct functional replacement for an SC50X110 when you need the added benefit of a field-adjustable stroke end. Ensure the mounting and port sizes match your existing setup.
