About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X250STC
The SC160X250STC is a double-acting pneumatic cylinder delivering 10053 N of push force at 0.5 MPa, scaling to 18095 N at the maximum operating pressure of 0.9 MPa. With a 250 mm stroke and a 40 mm diameter piston rod, this model is built for heavy linear actuation tasks where mid-stroke pivoting is required.
This configuration includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, and a centre trunnion mount (-TC suffix) supplied with the TCM1 bracket for swinging loads. The adjustable air cushion decelerates the piston smoothly over 29 mm at each end, protecting the assembly from impact.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X250STC Is Used
Heavy Pallet Transfer
The 18095 N max thrust moves loaded pallets between conveyor lines, with the centre trunnion allowing the cylinder to pivot as the lift angle changes.
Industrial Press Feed
Reliably pushes heavy steel sheets into a stamping press. The adjustable cushion and magnetic piston provide precise end-of-stroke deceleration and position feedback.
Swinging Gate Actuator
The TC centre trunnion mount is ideal for actuating a large, heavy safety gate or diverter chute, absorbing the arc motion without side-loading the rod bearings.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X250STC the Right Cylinder?
Choose the SC160 bore when your application requires a push force between the SC125 (6136 N at 0.5 MPa) and this model's 10053 N. For a 250 mm stroke, the rigid 40 mm rod handles axial loads well, but any significant side loading requires an external guide or rod support to prevent bearing wear and rod deflection.
To ensure a drop-in replacement, match five points: 160 mm bore, 250 mm stroke, PT port thread, centre trunnion (TC) mounting with the F-SC160TC bracket, and the built-in magnet for sensor compatibility. This tie-rod cylinder is not dimensionally interchangeable with ISO 15552 profiles.
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 SC160X250STC FAQ
At 0.5 MPa, the push force is 10053 N and the pull force is 9425 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 18095 N. The theoretical maximum at 1.0 MPa is 2050 kgf.
Yes. The -S suffix in the model code indicates a built-in magnet on the piston. This allows you to clamp AirTAC CMSG, DMSG, or EMSG reed and solid-state sensors directly onto the barrel for end-of-stroke detection.
