About the Airtac SC50 Standard Cylinder SC50X350TC
The AirTAC SC50X350TC is a double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa), sized for mid-range automation tasks that need a 350 mm linear stroke. Its 20 mm diameter piston rod and 21 mm adjustable air cushion help manage deceleration at the end of travel, while the PT1/4 ports keep flow rates high for responsive cycling.
This model ships with the TC centre trunnion mount and matching TCM1 bracket (F-SC50TC), allowing the cylinder body to pivot as the rod extends and retracts. The 350 mm stroke is well within the 1200 mm maximum standard stroke for the 50 mm bore, and the body length A of 150 mm keeps the overall envelope compact for pivoting installations.

Where the Airtac SC50 Standard Cylinder SC50X350TC Is Used
Part Diverter Gates
The centre trunnion mount lets the cylinder pivot as it pushes a diverter gate on a conveyor line, directing products between lanes with a 350 mm stroke.
Clamping & Fixturing
Provides 982 N of clamping force at 0.5 MPa for holding workpieces in CNC fixtures or welding jigs, where the pivoting body eases alignment with the clamp arm.
Linkage Actuation
Ideal for driving toggle linkages and lever mechanisms in packaging or assembly machinery, where the trunnion mount absorbs the arc motion of the linkage.
Is the Airtac SC50 Standard Cylinder SC50X350TC the Right Cylinder?
Choose the SC50 bore when your application needs roughly 980 N of push force at standard plant air; if you require more, stepping up to the SC63 bore provides 1559 N at 0.5 MPa. For strokes of 300 mm or longer, like this 350 mm unit, avoid placing side loads directly on the rod—external guides or a guided cylinder should be used to prevent rod bending and premature bearing wear.
When replacing an existing cylinder, match five points: 50 mm bore, 350 mm stroke, PT1/4 port thread, centre trunnion (TC) mounting, and confirm whether a magnet is needed (this model has no built-in magnet). The SC series is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC50X350TC FAQ
At 0.5 MPa, the push force is 982 N and the pull force is 825 N. At 0.7 MPa, push rises to 1374 N. The maximum operating force at 0.9 MPa is 1767 N push.
No. The 350 mm stroke on a 20 mm rod creates a long lever arm; side loads will bend the rod and damage the bearing. Always use an external linear guide or a guided cylinder to absorb transverse forces.
