About the Airtac SC50 Standard Cylinder SC50X220TC
The SC50X220TC is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 50 mm bore with a 220 mm stroke. It generates a push force of 982 N at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa, driven by a 20 mm diameter piston rod.
This model is factory-configured with a TC centre trunnion mount, supplied with the TCM1 bracket (part code F-SC50TC), allowing the cylinder to pivot during operation. The body length A is 150 mm, and the adjustable air cushion at each end is 21 mm long, providing smooth deceleration for mid-force automation tasks.

Where the Airtac SC50 Standard Cylinder SC50X220TC Is Used
Part Diverter Gates
The TC trunnion mount allows the cylinder body to pivot, making it perfect for actuating diverter gates on conveyor systems where a 220 mm stroke is needed to redirect packages or materials.
Clamping & Welding Fixtures
Delivers a controlled 982 N clamping force at 0.5 MPa. The pivoting action accommodates the swing-arm motion of welding and assembly fixtures, with adjustable cushioning to reduce impact.
Agricultural Machinery Linkages
Used in linkage actuation for hatches or chutes on agricultural equipment. The 20 mm rod and trunnion mount handle pivoting loads reliably in dusty environments with standard 40 µm filtered air.
Is the Airtac SC50 Standard Cylinder SC50X220TC the Right Cylinder?
Select the SC50X220TC for applications needing a pivoting actuator with around 982 N of force at standard plant pressure. If your load requires more force, stepping up to the 63 mm bore (SC63 series) provides 1559 N at the same 0.5 MPa. For lower force and a lighter, more compact design, the 40 mm bore delivers 628 N.
This 220 mm stroke is well within the 1200 mm maximum standard stroke for the 50 mm bore. The centre trunnion mount is ideal for swinging loads, but ensure the rod end is guided if side forces are present. For replacement, match five key points: 50 mm bore, 220 mm stroke, PT port thread, TC centre trunnion mounting, and the standard non-magnetic piston.
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 SC50X220TC FAQ
At the standard operating pressure of 0.5 MPa, the cylinder provides a push force of 982 N and a pull force of 825 N. The force increases linearly with pressure, reaching a maximum push force of 1767 N at the 0.9 MPa operating limit.
To ensure a direct fit, match the 50 mm bore, 220 mm stroke, PT (1/4 inch) port thread, and the TC centre trunnion mounting style. This model does not include a magnet, so if your sensors require a magnetic piston, you will need the -S suffix variant.
