About the Airtac SC50 Standard Cylinder SC50X63S
The SC50X63S is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 50 mm bore with a 63 mm stroke. At 0.5 MPa it generates 982 N of push force and 825 N on the pull stroke, making it a capable mid-range actuator for clamping and pressing tasks. The 20 mm diameter piston rod and PT1/4 ports provide a rigid, high-flow design for consistent cycle rates.
This model includes the -S suffix, meaning a built-in magnet is fitted as standard. This allows CMSG, DMSG, or EMSG reed and solid-state sensors to be mounted directly onto the barrel for non-contact position sensing. The body length A is 150 mm, giving a compact total extended length of 213 mm for easy integration into automated cells.

Where the Airtac SC50 Standard Cylinder SC50X63S Is Used
Automated Clamping
The 982 N push force at 0.5 MPa is ideal for pneumatic clamping fixtures in CNC machining and welding cells. The built-in magnet enables end-of-stroke confirmation to prevent cycle start without a fully clamped part.
Part Stops and Diverters
With a 63 mm stroke and rapid 30-800 mm/s speed range, this cylinder suits light-duty conveyor gates and part diverters. The adjustable air cushion at each end reduces impact noise and extends seal life in high-cycle sorting operations.
Laboratory Presses
The compact 213 mm extended length and clean air operation suit benchtop pneumatic presses for sample preparation. The TPU seals provide reliable low-friction performance within the standard -20 to +70 °C temperature window.
Is the Airtac SC50 Standard Cylinder SC50X63S the Right Cylinder?
Select the SC50X63S when your application requires around 1000 N of force and you need magnetic piston sensing. If your load demands more thrust, stepping up to the 63 mm bore provides 1559 N at the same 0.5 MPa pressure. For lower force applications, the 40 mm bore delivers 628 N and may reduce air consumption.
For a direct replacement, match five key points: 50 mm bore, 63 mm stroke, PT port thread, the built-in magnet (-S), and the basic mounting configuration. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders; always verify the body length A of 150 mm against your existing setup.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SC50 Standard Cylinder SC50X63S FAQ
At the standard operating pressure of 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 theoretical maximum force at 1.0 MPa is 200 kgf.
Yes. The -S suffix in the model code SC50X63S indicates a built-in magnet is installed inside the piston. You can clamp compatible AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel tie-rods to detect piston position without any additional brackets.
