About the Airtac SC50 Standard Cylinder SC50X15S
The SC50X15S is a compact-stroke variant of the AirTAC SC tie-rod cylinder, delivering 982 N of push force at 0.5 MPa from its 50 mm bore. With a short 15 mm stroke, it excels in clamping, ejecting, and precise short-travel positioning tasks where space is limited.
The built-in magnet (suffix -S) allows direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for reliable end-of-stroke detection. The 20 mm diameter piston rod and M16x1.5 rod thread provide robust connection, while the adjustable air cushion at each end decelerates the piston smoothly within a 21 mm cushion zone.

Where the Airtac SC50 Standard Cylinder SC50X15S Is Used
Short-Stroke Clamping
The 15 mm stroke and 982 N force at 0.5 MPa make this cylinder ideal for pneumatic clamping fixtures in machining and assembly, where fast, repeatable part holding is critical.
Component Ejection
Use the SC50X15S for ejecting parts from injection molds or stamping dies. The built-in magnet enables sensor confirmation that the ejector has fully retracted before the next cycle.
Diverter Gate Actuation
Operate small diverter gates on conveyor lines with this short-stroke cylinder. The tie-rod construction handles the repetitive impact, and the magnetic piston allows for position feedback.
Is the Airtac SC50 Standard Cylinder SC50X15S the Right Cylinder?
For higher force in the same footprint, step up to the 63 mm bore (1559 N at 0.5 MPa). If a lower force profile is acceptable, the 40 mm bore offers 628 N. This 15 mm stroke is a standard offering and does not require external guides for axial loads. To match this cylinder in a replacement, verify bore (50 mm), stroke (15 mm), PT port thread, the built-in magnet (-S), and the basic mount configuration.
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 SC50X15S FAQ
At 0.5 MPa operating pressure, 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 reaches 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
Yes. The -S suffix in SC50X15S designates a built-in magnet in the piston. This allows AirTAC CMSG, DMSG, or EMSG sensors to be clamped directly onto the cylinder barrel's tie-rod slots for non-contact position sensing.
