About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X350STC
The SC160X350STC is a double-acting tie-rod cylinder delivering 10053 N push and 9425 N pull at 0.5 MPa, rising to 18095 N push at the 0.9 MPa maximum operating pressure. Its 40 mm diameter hard-chrome piston rod and 29 mm adjustable air cushion handle heavy inertial loads smoothly, while the built-in magnet lets CMSG/DMSG/EMSG sensors clamp directly onto the barrel for rod-position feedback.
This genuine AirTAC SC series unit is factory-configured with a centre trunnion (TC) mount and the TCM1 bracket, allowing the cylinder to pivot freely in a clevis frame — ideal for swinging or articulating mechanisms. The 350 mm stroke sits well within the 1500 mm maximum standard stroke for bore 160, and the PT1/4 port threads match common pneumatic plumbing.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X350STC Is Used
Heavy Press & Clamp Actuation
With 18095 N of push force at 0.9 MPa, the SC160X350STC powers hydraulic-style clamping, pressing, and riveting stations on assembly lines, delivering consistent force stroke after stroke.
Swinging Gate & Diverter Arms
The factory-fitted centre trunnion mount and TCM1 bracket let the cylinder pivot as it strokes, making it a direct fit for material-handling diverters, chute gates, and bin-tipping mechanisms.
Sensor-Monitored Automation Cells
The built-in magnet (-S) accepts CMSG/DMSG/EMSG reed or solid-state sensors, enabling end-of-stroke confirmation and mid-stroke position sensing in automated work cells without extra brackets.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X350STC the Right Cylinder?
Choose the SC160 when your application needs roughly 10000 N of push force at standard shop air; the next step down, SC125, provides 6136 N push at 0.5 MPa, while stepping up to SC200 delivers 15708 N. At 350 mm stroke, ensure the rod is not subjected to unsupported side loads — if the load path is not perfectly axial, add an external guide rail or consider a guided cylinder to protect the rod bearing and seal.
For direct replacement, match five points: 160 mm bore, 350 mm stroke, PT port thread, centre trunnion (TC) mounting with TCM1 bracket, and the built-in magnet (-S) for sensor compatibility. This tie-rod cylinder is shorter than an ISO 15552 profile and is not dimensionally interchangeable with ISO 15552 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 SC160X350STC FAQ
At 0.7 MPa (7 bar) supply pressure, the SC160 bore generates 14074 N of push force on the extend stroke and 9425 N of pull force on the retract stroke, based on the official AirTAC thrust table for the 160 mm bore with a 40 mm rod.
No. The SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 cylinder of the same bore and stroke, so mounting dimensions, body length, and accessory interfaces do not match. Use it to replace another AirTAC SC160 tie-rod cylinder or a dimensionally verified tie-rod equivalent.
