About the Airtac SC50 Standard Cylinder SC50X190STC
The SC50X190STC is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa, rising to 1767 N at the maximum operating pressure of 0.9 MPa. With a 50 mm bore and a 190 mm stroke, it features a 20 mm diameter piston rod and an adjustable air cushion of 21 mm to decelerate the piston smoothly at each end of travel.
This specific model includes a built-in magnet (-S) for mounting CMSG/DMSG/EMSG sensors directly on the tie-rod barrel, and a TC centre trunnion mount (supplied with the TCM1 bracket, part code F-SC50TC) for pivoting applications. The standard PT port thread is 1/4 inch, and the body length A is 150 mm.

Where the Airtac SC50 Standard Cylinder SC50X190STC Is Used
Part Orientation on Conveyors
The 190 mm stroke and pivoting TC mount make this cylinder ideal for pusher or diverter arms on packaging lines, accurately sorting products with a 982 N push at standard line pressure.
Clamping in Welding Fixtures
With a built-in magnet for sensor confirmation and a trunnion mount to swing clear, it reliably clamps automotive components, delivering up to 1767 N of holding force for precise assembly.
Chute or Gate Actuation
The SC50X190STC pivots a material-handling gate on agricultural equipment. The adjustable cushion protects the cylinder at end-of-stroke, ensuring long service life in dusty conditions.
Is the Airtac SC50 Standard Cylinder SC50X190STC the Right Cylinder?
For applications requiring slightly less force, consider stepping down to the 40 mm bore (628 N at 0.5 MPa). If you need a higher force output, the 63 mm bore provides 1559 N at the same pressure. Ensure a complete replacement match by verifying five key points: 50 mm bore, 190 mm stroke, PT port thread, TC centre trunnion mount, and the built-in magnet for sensor compatibility. For strokes over 300 mm, assess side loads carefully; an external guide or guided cylinder is recommended to protect the rod bearing from bending moments.
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 SC50X190STC FAQ
At 0.5 MPa, the theoretical push force is 982 N and the pull force is 825 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1767 N. The maximum theoretical force at 1.0 MPa is 200 kgf.
No. The SC50X190STC is a double-acting cylinder that requires continuous air pressure to maintain its position. If pressure is lost or the directional valve is centered, the piston can drift. For load holding, you must add an external rod lock or a pilot-operated check valve.
