About the Airtac SC50 Standard Cylinder SC50X200STC
The AirTAC SC50X200STC is a double-acting tie-rod cylinder with a 50 mm bore and 200 mm stroke, pre-configured with a built-in magnet and a centre trunnion mounting. It produces 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 with an M16x1.5 rod thread.
This model features a body length A of 150 mm and an adjustable air cushion length of 21 mm to decelerate the piston smoothly. The -S suffix equips the barrel with a magnet for direct mounting of CMSG/DMSG/EMSG sensors, while the TC suffix supplies the F-SC50TC centre trunnion bracket, ideal for pivoting applications.

Where the Airtac SC50 Standard Cylinder SC50X200STC Is Used
Part Diverter Gates
The centre trunnion mount allows the cylinder body to pivot, making it suitable for actuating diverter gates on conveyor lines where the 982 N push force handles medium-weight package sorting.
Clamping & Fixturing
Delivers a controlled 1767 N clamping force at 0.9 MPa for holding workpieces during machining or welding. The built-in magnet enables end-of-stroke confirmation via barrel-mounted sensors.
Agricultural Machinery Linkage
Used in linkage actuation on sprayer booms or seed drills where a pivoting motion is required. The TPU seals and PT port suit standard mobile pneumatic systems.
Is the Airtac SC50 Standard Cylinder SC50X200STC the Right Cylinder?
Select the SC50 bore for pneumatic tasks needing a push force around 982 N at standard 0.5 MPa shop air. If your load requires more thrust, stepping up to the SC63 bore provides 1559 N at the same pressure. For lighter, more compact installations, the SC40 bore delivers 628 N.
For this 200 mm stroke, ensure the load is guided to prevent side-load bending on the 20 mm rod. When replacing an existing cylinder, match five key points: 50 mm bore, 200 mm stroke, PT port thread, centre trunnion (TC) mounting, and the built-in magnet (-S) for sensor compatibility.
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 SC50X200STC FAQ
At 0.5 MPa, the push force is 982 N and the pull force is 825 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
No. The SC50X200STC is a double-acting cylinder and does not lock or hold position when air pressure is exhausted. If load holding is required in a power-off state, you must add an external rod brake or a pilot-operated check valve.
