About the Airtac SC50 Standard Cylinder SC50X190S
The SC50X190S is a genuine AirTAC tie-rod cylinder with a 50 mm bore and 190 mm stroke, delivering 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa). Its 20 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration, making it a solid mid-range actuator for general automation.
This model includes the factory-installed -S magnet, so CMSG, DMSG, or EMSG reed and solid-state sensors can be clamped directly onto the barrel for non-contact position sensing. The compact tie-rod body (A-length 150 mm) keeps the total extended length to approximately 340 mm, fitting well into space-constrained machine frames.

Where the Airtac SC50 Standard Cylinder SC50X190S Is Used
Material Handling Gates
The 982 N push force at 0.5 MPa easily operates diverter gates and stops on light to medium-duty conveyor lines, with the magnetic piston enabling precise end-of-stroke confirmation.
Clamping & Fixturing
Provides controlled clamping force for CNC fixtures and welding jigs. The adjustable cushion reduces impact at the end of the 190 mm stroke, protecting the workpiece and tooling.
Press-Fit Assembly
Delivers up to 1767 N at the maximum 0.9 MPa operating pressure, suitable for light press-fit and insertion tasks in automated assembly cells where sensor feedback is required.
Is the Airtac SC50 Standard Cylinder SC50X190S the Right Cylinder?
For applications needing more force, stepping up to the SC63 series provides 1559 N at 0.5 MPa; if a lighter, faster actuator is preferred, the SC40 delivers 628 N. At a 190 mm stroke, the 20 mm rod is well-supported, but any side load should be managed with an external linear guide. When replacing an existing cylinder, match five points: 50 mm bore, 190 mm stroke, PT port thread, the built-in magnet (-S), and the basic (no bracket) mounting configuration.
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 SC50X190S FAQ
At the standard 0.5 MPa operating pressure, the cylinder produces 982 N pushing force and 825 N pulling force. At 0.7 MPa, push force increases to 1374 N, and at the maximum operating pressure of 0.9 MPa, it reaches 1767 N.
Yes. The -S suffix in SC50X190S indicates a built-in magnet on the piston. This allows you to mount AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly on the barrel's external tie-rod slots for reliable, non-contact position detection.
