About the Airtac SC50 Standard Cylinder SC50X150S
The AirTAC SC50X150S is a double-acting tie-rod cylinder that generates 982 N of push force at 0.5 MPa (1767 N at 0.9 MPa). Its 20 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for mid-range linear tasks.
The built-in magnet (-S suffix) allows CMSG, DMSG, or EMSG sensors to clamp directly onto the barrel for non-contact position sensing. With a 150 mm stroke and a body length A of 150 mm, this genuine AirTAC unit is a compact solution for automation requiring feedback.

Where the Airtac SC50 Standard Cylinder SC50X150S Is Used
Part Diverting
The 150 mm stroke and magnetic piston allow precise end-of-stroke sensing for diverting packages or components on a conveyor line.
Clamping Fixtures
Delivers consistent clamping force for CNC or welding fixtures, with sensor confirmation that the clamp is fully engaged before the cycle starts.
Automated Sorting Gates
Operates a sorting gate or flap in a material handling system, with the magnet confirming the open/closed state to the PLC.
Is the Airtac SC50 Standard Cylinder SC50X150S the Right Cylinder?
For higher force, step up to the SC63 (1559 N push at 0.5 MPa); for a lighter, more compact actuator, the SC40 offers 628 N. The 150 mm stroke is well within the 1200 mm maximum standard stroke for 50 mm bore cylinders.
When replacing, match five points: 50 mm bore, 150 mm stroke, PT port thread, the built-in magnet (-S) for sensor mounting, and the basic (no bracket) mounting style. Always verify that your directional valve and flow controls are sized for the PT1/4 ports.
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 SC50X150S FAQ
At 0.7 MPa, the push force is 1374 N. The pull force at the same pressure is slightly lower due to the rod area, delivering 825 N at 0.5 MPa.
Yes. The -S suffix indicates a built-in magnet. You can mount AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly on the barrel tie-rods to detect piston position.
