About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X450STC
The AirTAC SC160X450STC is a double-acting single-rod pneumatic cylinder delivering 10053 N of push force at 0.5 MPa and up to 18095 N at the 0.9 MPa maximum operating pressure. With a 450 mm stroke and a 40 mm diameter piston rod, it provides robust linear actuation for medium-to-heavy industrial tasks.
This model is equipped with a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, and a centre trunnion mount (TC suffix, supplied with TCM1 bracket F-SC160TC) for pivoting applications. The adjustable air cushion (29 mm length) decelerates the piston smoothly at stroke ends, protecting the end caps during high-cycle operation.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X450STC Is Used
Conveyor Diverter Gates
The 18095 N maximum thrust at 0.9 MPa powers heavy diverter gates on wide conveyor lines, while the centre trunnion mount allows the cylinder to pivot as the gate swings through its arc.
Press Clamping Systems
Delivers 10053 N of steady clamping force at 0.5 MPa for holding large workpieces during machining or welding. The adjustable cushion prevents impact shock when the clamp engages.
Pivoting Lift Tables
The TC centre trunnion mount is ideal for scissor-lift and tilt-table mechanisms. Magnetic sensors on the barrel provide end-of-stroke confirmation for precise cycle control.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X450STC the Right Cylinder?
Choose the SC160 bore when your application needs between 10053 N and 18095 N of push force. For lighter loads, stepping down to the SC125 bore reduces push force to 6136 N at 0.5 MPa, while stepping up to the SC200 bore provides 15708 N at the same pressure. The 450 mm stroke is within the standard range for this bore.
For strokes of this length, ensure the load is guided externally if side forces are present—the 40 mm rod can bend under unsupported side loads. To replace an existing cylinder, match all five key points: 160 mm bore, 450 mm stroke, PT port thread, centre trunnion (TC) mounting with TCM1 bracket, and the built-in magnet (-S) for sensor compatibility.
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 SC160X450STC FAQ
At the standard 0.5 MPa operating pressure, push force is 10053 N and pull force is 9425 N. At the maximum operating pressure of 0.9 MPa, push force reaches 18095 N. The theoretical maximum at 1.0 MPa is 2050 kgf.
No. The SC160 is a double-acting cylinder and does not lock or hold position when pressure is exhausted or the directional valve is centred. If load holding is required, add an external rod brake, a pilot-operated check valve, or a mechanical lock.
