About the Airtac SC50 Standard Cylinder SC50X185TC
The SC50X185TC is a double-acting pneumatic cylinder delivering a push force of 982 N at 0.5 MPa (1374 N at 0.7 MPa), making it a robust mid-range actuator for industrial automation. With a 50 mm bore, 20 mm piston rod, and a 185 mm stroke, it features an adjustable air cushion (21 mm length) to decelerate the piston quietly at end-of-travel.
This model is configured with a centre trunnion (TC) mount, supplied with the TCM1 bracket (F-SC50TC), allowing the cylinder to pivot during operation for swinging or angular load paths. The body length A is 150 mm, giving a total extended length of approximately 335 mm. It uses standard PT ports (PT1/4) and TPU seals for a temperature range of -20 to +70 °C.

Where the Airtac SC50 Standard Cylinder SC50X185TC Is Used
Part Diverter Gates
The centre trunnion mount allows the cylinder body to pivot, making it ideal for actuating diverter flaps on conveyor lines where the cylinder must swing through an arc.
Clamping & Fixturing
With 982 N of clamping force at just 0.5 MPa, this cylinder provides secure workpiece holding for machining or welding fixtures, with the trunnion allowing flexible mounting angles.
Press & Forming Mechanisms
The 50 mm bore delivers up to 1767 N at the maximum operating pressure of 0.9 MPa, suitable for light-duty pressing, stamping, or bending operations in assembly cells.
Is the Airtac SC50 Standard Cylinder SC50X185TC the Right Cylinder?
Choose the SC50 bore when your application requires between 825 N (pull) and 982 N (push) at 0.5 MPa. If you need more force, step up to the SC63 which provides 1559 N push at the same pressure. For lighter, more compact requirements, the SC40 delivers 628 N push.
For this 185 mm stroke, side-loading is a key consideration. Ensure the load is guided externally and aligned axially with the rod; the trunnion mount handles pivoting in one plane but does not support the rod against lateral forces. To replace an existing cylinder, match five points: 50 mm bore, 185 mm stroke, PT1/4 port thread, centre trunnion (TC) mounting, and no magnet.
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 SC50X185TC FAQ
At the standard 0.5 MPa operating pressure, the push force is 982 N and the pull force is 825 N. At 0.7 MPa, push force increases to 1374 N. The maximum theoretical force at 1.0 MPa is 200 kgf.
Not directly. The TC suffix means this cylinder is designed to pivot on its centre trunnion. Replacing it with a basic or foot-mounted (LB) cylinder would change the motion path and likely cause binding. You must match the mounting type (TC with TCM1 bracket) for a drop-in replacement.
