About the Airtac SC50 Standard Cylinder SC50X30STC
The SC50X30STC is a 50 mm bore, 30 mm stroke double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1767 N at 0.9 MPa). Its short 30 mm stroke suits compact clamping and ejector stations where space is tight, and the 20 mm diameter piston rod provides excellent rigidity for this stroke length.
This model is factory-configured with a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and a centre trunnion mount (TC) that includes the TCM1 bracket (F-SC50TC). The body length A is 150 mm, giving a compact extended length of just 180 mm. It uses standard PT ports (PT1/4) and TPU seals for a -20 to +70 °C operating range.

Where the Airtac SC50 Standard Cylinder SC50X30STC Is Used
Compact Clamping Fixtures
The 30 mm stroke and 982 N force at 0.5 MPa make it perfect for small pneumatic clamps in CNC machining or welding jigs, with sensor confirmation of clamp position.
Part Ejection & Sorting
Use the short, fast stroke to eject parts from a conveyor or sort small components. The trunnion mount allows flexible angular positioning of the cylinder body.
Pivoting Linkage Actuation
The centre trunnion mount is designed for linkages that swing through an arc, such as opening a small gate or diverting product flow on a packaging line.
Is the Airtac SC50 Standard Cylinder SC50X30STC the Right Cylinder?
For higher force requirements, consider stepping up to a 63 mm bore (1559 N at 0.5 MPa). If a smaller footprint is needed, the 40 mm bore delivers 628 N. The trunnion mount allows the cylinder to pivot, making it ideal for angular motion applications—ensure the pivot axis is aligned to avoid binding. When replacing, match bore (50), stroke (30), port thread (PT1/4), the TC centre trunnion mount, and the -S magnet for sensor compatibility.
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 SC50X30STC FAQ
At the standard 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 increases to 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
Yes. The -S suffix indicates a built-in magnet in the piston, allowing you to clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel to detect end-of-stroke position without additional brackets.
