About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X250TC
The SC160X250TC is a robust double-acting tie-rod cylinder delivering a substantial push force of 10053 N at 0.5 MPa (up to 18095 N at 0.9 MPa). Its 250 mm stroke and 40 mm diameter piston rod suit heavy linear actuation tasks where a pivoting mount is required.
This configuration includes a centre trunnion (TC) mount, supplied with the TCM1 bracket (part code F-SC160TC), allowing the cylinder to pivot during operation. The body length A is 239 mm, the adjustable air cushion is 29 mm, and the PT3/4 port supplies filtered air for smooth deceleration at stroke ends.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X250TC Is Used
Heavy Press & Clamping
Generates over 10 kN of force at standard line pressure, making it ideal for powerful clamping fixtures, forming presses, and heavy assembly jigs.
Pivoting Conveyor Gates
The centre trunnion mount allows the cylinder to swing, perfect for actuating heavy diverter gates or tilting mechanisms on large material handling lines.
Large Damper & Valve Actuation
Delivers the high thrust needed to open and close large industrial dampers, valves, and hopper doors in processing plants and silo installations.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X250TC the Right Cylinder?
For applications needing more force, step up to the SC200 bore (15708 N push at 0.5 MPa); for a lighter, more compact solution, the SC125 bore offers 6136 N at 0.5 MPa. The centre trunnion mount is ideal for swinging or pivoting loads, but ensure the trunnion axis is aligned to avoid binding.
When replacing this cylinder, match five critical points: 160 mm bore, 250 mm stroke, PT3/4 port thread, the TC centre trunnion mounting accessory, and the absence of a magnet. At this stroke length, the 40 mm rod is robust, but any significant side load requires an external guide rail to prevent rod bearing damage and ensure long service life.
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 SC160X250TC FAQ
At 0.7 MPa (7 bar), the theoretical push force for a 160 mm bore is 14074 N. The pull force on the retract stroke is lower due to the 40 mm rod area, delivering 9425 N at 0.5 MPa.
No. The SC160X250TC is a standard double-acting cylinder and will drift or drop if pressure is lost or the directional valve is centered. To hold a load safely without live pressure, you must add an external rod lock, a pilot-operated check valve, or a mechanical brake.
