About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X50TC
The SC160X50TC is a double-acting pneumatic cylinder with a 160 mm bore and a short 50 mm stroke, configured with a centre trunnion (TC) mount for pivoting applications. It generates a substantial push force of 10053 N at 0.5 MPa and up to 18095 N at the maximum operating pressure of 0.9 MPa, making it suitable for heavy clamping or short-throw lifting.
This model features a 40 mm diameter piston rod with an M36x2 male thread and PT3/4 port connections. The adjustable air cushion (29 mm length) decelerates the piston at end-of-stroke, and the TC mount (supplied with TCM1 bracket, order code F-SC160TC) allows the cylinder body to pivot as the rod extends and retracts. Total extended body length is 289 mm (A=239 mm + 50 mm stroke).

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X50TC Is Used
Heavy Part Clamping
The 10053 N force at 0.5 MPa and short 50 mm stroke provide a fast, powerful clamp for welding fixtures or machining centres holding large fabrications.
Pivoting Press Actuator
The TC centre trunnion mount allows the cylinder to swing, making it ideal for actuating a pivoting press platen or a heavy-duty toggle mechanism.
Short-Throw Diverter Gate
Use the 50 mm stroke for a high-force diverter gate on a conveyor line, where the trunnion mount simplifies alignment with the swinging gate arm.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X50TC the Right Cylinder?
Choose the SC160 bore when your application requires a push force between roughly 10053 N (0.5 MPa) and 18095 N (0.9 MPa). If your force requirement is lower, consider stepping down to the SC125 bore (6136 N at 0.5 MPa) to save space and air consumption. For a direct replacement, match five key points: 160 mm bore, 50 mm stroke, PT3/4 port thread, TC centre trunnion mounting (F-SC160TC), and the absence of a magnet sensor option on this model.
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 SC160X50TC 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 reaches 18095 N. The theoretical maximum force at 1.0 MPa is 2050 kgf.
No. The SC160X50TC is a double-acting cylinder and will not hold its position if air pressure is exhausted or lost. The piston will drift or drop under load. For load holding without live pressure, you must add an external rod brake, a mechanical lock, or a pilot-operated check valve.
