About the Airtac SC50 Standard Cylinder SC50X100STC
The SC50X100STC is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa and up to 1767 N at 0.9 MPa operating pressure. With a 100 mm stroke and 20 mm diameter piston rod, this model is well-suited for medium-duty clamping, pressing, and sorting tasks where a compact tie-rod design is preferred.
This configuration includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, enabling precise end-of-stroke detection. The centre trunnion mount (TC) with the included TCM1 bracket allows the cylinder to pivot, making it ideal for swinging or articulating machine elements.

Where the Airtac SC50 Standard Cylinder SC50X100STC Is Used
Part Diverter Gates
The centre trunnion mount allows the cylinder body to pivot, making it perfect for actuating swinging gates on conveyor lines to sort or divert packages.
Clamping & Welding Fixtures
Delivers a controlled 982 N clamping force at standard line pressure. The magnetic piston enables sensor confirmation of clamp closure before a welding or machining cycle starts.
Articulating Machine Guards
Use the TC pivot mount to raise and lower hinged safety guards. The adjustable air cushion at each end ensures a quiet, low-impact stop, extending the guard's mechanical life.
Is the Airtac SC50 Standard Cylinder SC50X100STC the Right Cylinder?
For applications requiring slightly less force, stepping down to a 40 mm bore provides 628 N at 0.5 MPa. If higher force is needed, the 63 mm bore offers 1559 N at the same pressure. The SC50X100STC is a genuine AirTAC tie-rod cylinder; for a successful replacement, match the 50 mm bore, 100 mm stroke, PT port thread, centre trunnion (TC) mounting, and the integrated magnet (-S) 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 SC50X100STC FAQ
At the standard 0.5 MPa operating pressure, the cylinder provides 982 N extending (push) and 825 N retracting (pull). At the maximum operating pressure of 0.9 MPa, the push force increases to 1767 N.
The TC suffix indicates the cylinder is supplied with the centre trunnion and TCM1 bracket (part code F-SC50TC). While the trunnion can be removed, this model is specifically configured for pivoting applications. For a fixed linear mount, consider an LB foot or FA/FB flange variant.
