About the Airtac SCJ50 Standard Cylinder SCJ50X10-10
The AirTAC SCJ50X10-10 is a double-acting, single-rod pneumatic cylinder with a nominal 10 mm stroke, field-adjustable by up to 10 mm via a rear-cap screw. This 50 mm bore actuator delivers 982 N of push force at 0.5 MPa, making it a compact yet powerful solution for precise end-stop tuning.
With a 20 mm rod diameter and PT1/4 ports, the SCJ50X10-10 fits into tight machine spaces where commissioning trials or wear take-up require fine positional adjustment without swapping the cylinder. Its tie-rod construction and adjustable air cushion ensure reliable deceleration, while the 10 mm adjustment range lets operators dial in the exact stroke end on the fly.
Airtac SCJ50 Standard Cylinder SCJ50X10-10 Technical Specifications
| Model | Airtac SCJ50 Standard Cylinder SCJ50X10-10 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø50 mm |
| Nominal stroke | 10 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 SCJ50X10-10 Is Used
Commissioning & Setup
The 10 mm adjustable stroke allows technicians to fine-tune the cylinder's end position during machine commissioning without removing the actuator, speeding up initial setup and calibration.
Wear Compensation
In high-cycle applications, the rear adjusting screw can take up mechanical play or wear in tooling, maintaining precise positioning over the cylinder's service life.
Format Changeover
Quickly adjust the stroke end for different product sizes or tooling setups on a packaging or assembly line, reducing downtime between production runs.
Is the Airtac SCJ50 Standard Cylinder SCJ50X10-10 the Right Cylinder?
Choose the SCJ50X10-10 when you need a 50 mm bore with a short 10 mm nominal stroke and the ability to fine-tune the end position by up to 10 mm. If your application demands more force, step up to the 63 mm bore SCJ63 series, which provides 1559 N push at 0.5 MPa. For a fixed, non-adjustable stroke, the standard SC50 series is a simpler alternative. This model is a direct replacement for any AirTAC SCJ50X10-10 cylinder with PT ports and basic mounting; ensure the -10 adjustable range matches your existing setup.
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 SCJ50X10-10 FAQ
At 0.5 MPa, the push force is 982 N and the pull force is 825 N. The maximum push force at the 0.9 MPa operating limit is 1767 N. Because it is a single-rod cylinder, push force is always greater than pull force.
A screw in the rear cap sets the stroke end position within a 10 mm range. This shortens the effective stroke from the nominal 10 mm down to a minimum of 0 mm. It does not change the cylinder's force or speed, only the piston's stopping point.
