About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X20S
The SC160X20S is a double-acting tie-rod cylinder with a 160 mm bore and a short 20 mm stroke, ideal for compact clamping, ejecting, or positioning tasks that need high force in a limited linear travel. At 0.5 MPa air pressure it generates 10053 N pushing force and 9425 N pulling force, with a maximum operating thrust of 18095 N at 0.9 MPa.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be mounted directly on the barrel for non-contact position sensing. The 40 mm diameter piston rod features an M36x2 knuckle thread, and the cylinder body length (A) is 239 mm, giving a total extended length of approximately 259 mm. Port size is PT3/4 with an adjustable air cushion length of 29 mm to decelerate the piston smoothly at end of stroke.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X20S Is Used
Heavy-Duty Clamping
Short 20 mm stroke with 10053 N force at 0.5 MPa securely holds large weldments or castings during machining, preventing movement under high tool pressure.
Die Ejection
Delivers a powerful, brief push to eject heavy stampings or molded parts from dies, with the built-in magnet confirming full retraction between cycles.
Press-Fit Assembly
Applies controlled 18095 N peak force at 0.9 MPa for pressing bearings, bushings, or pins into housings on a semi-automated assembly station.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X20S the Right Cylinder?
Choose the SC160 bore when your application needs push force in the 10000 N class at standard plant pressure. If your force requirement is closer to 6000 N, stepping down to the SC125 bore (6136 N push at 0.5 MPa) can reduce air consumption and physical size. For higher force demands, the SC200 bore offers 15708 N at the same pressure.
When replacing an existing cylinder, match these five points exactly: 160 mm bore, 20 mm stroke, PT3/4 port thread, the built-in magnet for sensor compatibility, and the basic (no bracket) mounting configuration. The SC series is a tie-rod cylinder 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 AIRTAC SC125-160 Standard Cylinder SC160X20S FAQ
At 0.5 MPa, the push force is 10053 N and the pull force is 9425 N. At 0.7 MPa, push force is 14074 N. The maximum operating push force at 0.9 MPa is 18095 N. The theoretical maximum at 1.0 MPa is 2050 kgf.
The -S suffix equips the piston with a magnet designed for AirTAC CMSG (reed), DMSG, and EMSG (solid-state) sensors, which clamp directly onto the cylinder barrel's tie-rod slots. Always verify sensor compatibility with your controller's input requirements.
