About the Airtac SC50 Standard Cylinder SC50X200TC
The AirTAC SC50X200TC is a double-acting tie-rod cylinder with a 50 mm bore and 200 mm stroke, factory-equipped with a TC centre trunnion mount for pivoting applications. Operating on filtered air at 0.15–1.0 MPa, it generates 982 N of push force at 0.5 MPa and up to 1767 N at 0.9 MPa, driven by a 20 mm diameter piston rod with M16x1.5 male threads.
This model uses the standard PT1/4 port and includes an adjustable air cushion (21 mm length) at both ends to decelerate the piston quietly. The body length A is 150 mm, giving a total extended length of approximately 350 mm. TPU seals with NBR wear rings provide a -20 to +70 °C working range, and the TC mount ships with the TCM1 bracket (part code F-SC50TC) for direct integration into swinging or articulating mechanisms.

Where the Airtac SC50 Standard Cylinder SC50X200TC Is Used
Conveyor Diverter Gates
The centre trunnion mount allows the cylinder body to pivot as it actuates a diverter gate or flipper on a packaging or sorting conveyor, handling 982 N of push force at standard line pressure.
Clamping & Fixturing
Delivers consistent clamping force up to 1767 N at 0.9 MPa for machining fixtures and welding jigs. The adjustable cushion reduces impact shock, preserving fixture alignment over high-cycle runs.
Process Valve Actuation
Pivots a quarter-turn ball or butterfly valve via a linkage. The TC trunnion absorbs the arc motion, and the 20 mm rod provides the stiffness needed for repetitive torque transfer in water treatment or chemical dosing lines.
Is the Airtac SC50 Standard Cylinder SC50X200TC the Right Cylinder?
Choose the SC50X200TC when your application needs a centre-pivoting cylinder in the 1000 N force class at 0.5 MPa. If you require more force, step up to the SC63 bore (1559 N push at 0.5 MPa); for a lighter, more compact solution, the SC40 bore delivers 628 N. The 200 mm stroke is well within the 1200 mm maximum standard stroke for this bore, so no special stroke order is needed.
When replacing an existing unit, match five points exactly: 50 mm bore, 200 mm stroke, PT1/4 port thread, TC centre trunnion mounting (F-SC50TC), and the absence of a magnet. For strokes of 300 mm or longer, consider an external guide or a guided cylinder to protect the rod from side-load bending, though at 200 mm the rod bearing is typically adequate for purely axial 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 SC50X200TC FAQ
At 0.5 MPa (5 bar) the cylinder pushes with 982 N and pulls with 825 N. At the maximum operating pressure of 0.9 MPa, push force rises to 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf (1960 N push).
No. The SC series is a tie-rod cylinder that is shorter in overall length than an ISO 15552 profile cylinder, so the mounting dimensions and body length do not interchange. Only replace another AirTAC SC50 tie-rod cylinder with matching bore, stroke, port thread, and TC mount.
