About the Airtac SCJ50 Standard Cylinder SCJ50X152-10S
The SCJ50X152-10S is a double-acting, single-rod pneumatic cylinder with a rear-cap adjusting screw, offering a 10 mm field-adjustable stroke range. With a 50 mm bore, it delivers a push force of 982 N at 0.5 MPa, making it a strong candidate for mid-range clamping, pressing, and positioning tasks where the final stroke end needs fine-tuning during commissioning or format changes.
This model features a built-in magnet, allowing easy mounting of CMSG, DMSG, or EMSG sensors directly onto the tie-rod barrel for precise end-of-stroke or mid-stroke position feedback. The 20 mm rod and PT1/4 ports provide robust air flow, while the adjustable air cushion decelerates the piston smoothly, protecting the end cap over millions of cycles.
Airtac SCJ50 Standard Cylinder SCJ50X152-10S Technical Specifications
| Model | Airtac SCJ50 Standard Cylinder SCJ50X152-10S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø50 mm |
| Nominal stroke | 152 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 SCJ50X152-10S Is Used
Commissioning & Fine-Tuning
The 10 mm adjustment screw allows technicians to dial in the exact stroke end on a new machine without machining custom stops, speeding up factory acceptance testing.
Sensor-Monitored Part Stops
With its built-in magnet, the SCJ50X152-10S pairs with reed switches to confirm retraction on a conveyor gate, ensuring a pallet has cleared before the next cycle begins.
Wear Compensation in Clamping
In repetitive clamping fixtures, the adjustable stroke compensates for jaw or workpiece wear over time, maintaining consistent clamping force without replacing the cylinder.
Is the Airtac SCJ50 Standard Cylinder SCJ50X152-10S the Right Cylinder?
Choose the SCJ50X152-10S when you need a mid-bore cylinder with sensor-ready position feedback and a small, 10 mm stroke-end adjustment window. If you require more force, stepping up to the 63 mm bore provides 1559 N of push force at the same pressure. For applications needing a fixed, non-adjustable stroke, the standard SC series is a more economical choice. This cylinder is a direct replacement for another AirTAC SCJ50X152-10S with a magnet and PT threads.
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 SCJ50X152-10S FAQ
The push force is 982 N at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. The pull force is lower at 825 N at 0.5 MPa due to the 20 mm single rod reducing the piston area on the retract side.
Yes, provided the bore (50 mm) and port thread (PT1/4) match. The SCJ body is slightly longer to house the adjustment mechanism, so verify the available space. The 10 mm adjustment range allows you to fine-tune the stroke end, which is the key advantage over a fixed-stroke SC model.
