About the Airtac SC50 Standard Cylinder SC50X175TC
The SC50X175TC is a double-acting pneumatic cylinder delivering 982 N of push force and 825 N of pull force when operated at 0.5 MPa. With a 50 mm bore and 175 mm stroke, it features a 20 mm piston rod with M16x1.5 male threads and an adjustable air cushion of 21 mm at each end to decelerate the piston smoothly.
This model includes the TC centre trunnion mounting, supplied with the TCM1 bracket (order reference F-SC50TC), which allows the cylinder to pivot during operation—ideal for swinging or articulating loads. The body length A is 150 mm, and the total extended length is approximately 325 mm. Standard PT ports are sized at 1/4 inch, and the operating pressure range is 0.15–1.0 MPa with a speed of 30–800 mm/s.

Where the Airtac SC50 Standard Cylinder SC50X175TC Is Used
Part Diverter Gates
The centre trunnion mount lets this cylinder pivot as it actuates a diverter gate on a conveyor line, sorting packages by weight class with 982 N of push force at standard shop air pressure.
Clamping Fixtures
Provides consistent 825 N pull force to lock a pivoting clamp arm in a CNC welding fixture. The adjustable cushion reduces impact and vibration at the end of the 175 mm stroke.
Tilt Mechanism Actuator
Drives a 175 mm linear stroke to tilt a small hopper or chute. The TC trunnion absorbs the arc motion, and the 20 mm rod handles the repetitive cycling without buckling.
Is the Airtac SC50 Standard Cylinder SC50X175TC the Right Cylinder?
Choose the SC50 bore for applications needing up to 982 N at 0.5 MPa. If your force requirement is lower, the SC40 bore provides 628 N; for higher force, the SC63 bore steps up to 1559 N at the same pressure. Always match the bore, 175 mm stroke, PT port thread, and centre trunnion mounting when replacing an existing cylinder.
For strokes of 175 mm, side loading is typically well-managed by the 20 mm rod, but avoid direct lateral forces on the rod end. If the load is not guided externally, consider adding a linear guide or switching to a guided cylinder to prevent rod bending and premature seal wear.
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 SC50X175TC FAQ
At the standard operating pressure of 0.5 MPa, this cylinder generates 982 N of push force on the outstroke and 825 N of pull force on the instroke. At the maximum operating pressure of 0.9 MPa, the push force reaches 1767 N.
Match these five points: 50 mm bore, 175 mm stroke, PT (1/4 inch) port thread, the TC centre trunnion mount with TCM1 bracket (F-SC50TC), and the standard TPU seal. The SC series is a tie-rod design, so it is dimensionally interchangeable only with another AirTAC SC50 cylinder with the same specifications.
