About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X55TC
The SC160X55TC is a double-acting pneumatic cylinder delivering substantial force in a compact 55 mm stroke. At 0.5 MPa it generates 10053 N pushing and 9425 N pulling, making it suitable for medium-stroke clamping, pressing, and lifting tasks that require a robust 40 mm diameter piston rod.
This model is configured with a TC centre trunnion mount (supplied with TCM1 bracket, order code F-SC160TC), allowing the cylinder to pivot during operation. The tie-rod construction keeps the body length A to 239 mm, and the adjustable air cushion (29 mm length) decelerates the piston smoothly at stroke end. Ports are PT3/4 with an M36x2 rod thread.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X55TC Is Used
Heavy Clamping Fixtures
The 10053 N push force at 0.5 MPa securely clamps large weldments or castings in machining centres, with the trunnion mount allowing the cylinder body to self-align during actuation.
Pivoting Transfer Gates
Ideal for actuating heavy-duty diverter gates on conveyor lines. The TC mount lets the cylinder swing as it extends and retracts the 55 mm stroke, directing pallets or large packages.
Mould Press Ejection
Delivers a controlled 55 mm push to eject large parts from moulds. The adjustable cushion absorbs impact energy, protecting the tooling during high-cycle ejection sequences.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X55TC the Right Cylinder?
For higher force at the same pressure, step up to the 200 mm bore (15708 N at 0.5 MPa); for a lighter, more compact solution, the 125 mm bore offers 6136 N. When replacing this cylinder, match five points: 160 mm bore, 55 mm stroke, PT3/4 port thread, TC centre trunnion mounting, and the non-magnetic piston (no -S suffix). The trunnion pivot handles angular movement, but ensure the load is guided to prevent side-loading the 40 mm rod.
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 SC160X55TC FAQ
At the standard 0.5 MPa operating pressure, this cylinder produces 10053 N pushing force and 9425 N pulling force. At the maximum operating pressure of 0.9 MPa, the pushing force increases to 18095 N.
Yes, the TC suffix indicates a centre trunnion mount. The cylinder body pivots on the trunnion pins, which is essential for applications where the attached load moves through an arc. The matching TCM1 bracket (F-SC160TC) is included for mounting.
