About the Airtac SC50 Standard Cylinder SC50X165S
The SC50X165S is a double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa) from a 50 mm bore. Its 165 mm stroke sits within the standard range for this bore, and the built-in magnet allows CMSG, DMSG, or EMSG sensors to clamp directly onto the barrel for rod-position feedback.
With a 20 mm diameter piston rod and M16x1.5 rod thread, this cylinder handles moderate push-pull tasks. The adjustable air cushion (21 mm length) decelerates the piston quietly at end-of-stroke, and the PT1/4 port supplies standard filtered air. Total extended body length is approximately 315 mm (150 mm body length A + 165 mm stroke).

Where the Airtac SC50 Standard Cylinder SC50X165S Is Used
Sensor-Monitored Part Transfer
The built-in magnet and 165 mm stroke suit linear transfer units where CMSG/DMSG sensors confirm extend and retract positions for pick-and-place sequencing.
Clamping with Position Verification
Apply 982 N of clamping force at 0.5 MPa while magnetic sensors signal the control system that the clamp has fully engaged, preventing cycle-start errors.
Divert Gate Actuation
Operate a 165 mm throw divert gate on a packaging line. The adjustable cushion softens the gate stop, and the magnet provides end-of-travel confirmation.
Is the Airtac SC50 Standard Cylinder SC50X165S the Right Cylinder?
For applications needing slightly more force, step up to the 63 mm bore (1559 N push at 0.5 MPa); for a lighter, faster actuator, the 40 mm bore offers 628 N. When ordering a replacement, match five points: 50 mm bore, 165 mm stroke, PT port thread, the built-in magnet (-S suffix), and any mounting accessory. The SC series is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC50X165S FAQ
At 0.5 MPa the cylinder pushes with 982 N and pulls with 825 N. At 0.7 MPa push force rises to 1374 N. The maximum operating pressure of 1.0 MPa yields a theoretical push of 1767 N (200 kgf).
Yes. The -S suffix indicates a built-in magnet inside the piston, so CMSG (reed) and DMSG/EMSG (solid-state) sensors mount directly onto the barrel tie-rods to detect piston position without external brackets.
