About the Airtac SC50 Standard Cylinder SC50X190TC
The AirTAC SC50X190TC is a double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa and 1767 N at 0.9 MPa. Its 190 mm stroke suits medium-reach clamping and transfer tasks, with a 20 mm rod diameter providing solid column strength.
This model includes the TC centre trunnion mount, supplied with the TCM1 bracket, allowing the cylinder to pivot during operation. The adjustable air cushion at each end decelerates the piston smoothly, and the PT1/4 ports connect easily to standard pneumatic lines.

Where the Airtac SC50 Standard Cylinder SC50X190TC Is Used
Pivoting Clamp Arms
The TC trunnion mount allows the SC50X190TC to swing freely, perfect for clamping fixtures that rotate into place on assembly lines.
Conveyor Diverters
With 190 mm of stroke and 982 N of force, this cylinder reliably actuates diverter gates on packaging or material-handling conveyors.
Machine Tool Actuation
Delivers consistent linear motion for tool changers or indexers, where the trunnion mount absorbs reaction forces smoothly.
Is the Airtac SC50 Standard Cylinder SC50X190TC the Right Cylinder?
Selecting the SC50X190TC means matching bore, stroke, and the TC pivot mount. For higher force, the SC63 bore offers 1559 N push at 0.5 MPa; for a lighter, more compact option, the SC40 provides 628 N. The 190 mm stroke is non-standard but well within the 1200 mm maximum for this bore. The centre trunnion is ideal for applications where the cylinder body must swing, reducing rod bending from misaligned loads.
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 SC50X190TC FAQ
At 0.5 MPa, it pushes with 982 N and pulls with 825 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1767 N.
No. The SC series is a tie-rod design and is shorter than ISO 15552 cylinders. It is a direct replacement only for other AirTAC SC cylinders with matching bore, stroke, PT ports, and TC mount.
