About the Airtac SCJ50 Standard Cylinder SCJ50X5-10S
The SCJ50X5-10S is a compact double-acting, single-rod cylinder with a field-adjustable stroke end, offering a 10mm adjustment range via a rear-cap screw. This model delivers 982 N of push force at 0.5 MPa, making it suitable for precise end-stop positioning in light clamping or ejection tasks.
Equipped with a built-in magnet, this unit allows direct mounting of CMSG/DMSG/EMSG sensors for reliable end-of-stroke detection without external brackets. The 20mm rod and PT1/4 port ensure compatibility with standard AirTAC accessories.
Airtac SCJ50 Standard Cylinder SCJ50X5-10S Technical Specifications
| Model | Airtac SCJ50 Standard Cylinder SCJ50X5-10S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø50 mm |
| Nominal stroke | 5 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 SCJ50X5-10S Is Used
Commissioning Fine-Tuning
Dial in the exact stroke end position on new automation cells without swapping cylinders or machining hard stops.
Wear Compensation
Adjust the stroke end to take up mechanical play or pad wear in clamping fixtures over time.
Short-Stroke Positioning
Ideal for applications needing a 5mm nominal stroke with the ability to shorten it for precise part contact.
Is the Airtac SCJ50 Standard Cylinder SCJ50X5-10S the Right Cylinder?
Choose the SCJ50X5-10S when you need to fine-tune the stroke end by up to 10mm during commissioning or changeovers. For higher force, step up to the 63mm bore providing 1559 N push at 0.5 MPa. If a fixed stroke is sufficient, the standard SC series offers a simpler, lower-cost alternative. This model is a direct replacement for any SCJ50X5-10S with PT ports and a magnet.
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 SCJ50X5-10S FAQ
At 0.5 MPa, it provides 982 N of push force and 825 N of pull force due to the single-rod design. The adjustable screw does not affect force output.
A rear-cap screw limits the piston's retract stroke end by up to 10mm. The nominal 5mm stroke is the maximum; the screw only shortens it.
