About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X160TC
The AirTAC SC125X160TC is a double-acting single-rod pneumatic cylinder delivering 6136 N of push force at 0.5 MPa and 8590 N at 0.7 MPa. With a 160 mm stroke and centre trunnion mounting, it's built for applications requiring the cylinder body to pivot during operation.
This model features a 32 mm diameter piston rod with M27x2 male knuckle thread and PT1/2 ports. The adjustable air cushion at each end is 28 mm long, providing smooth deceleration for the 125 mm bore piston. As part of the ISO 6430 class, its speed range is 30-500 mm/s.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X160TC Is Used
Agricultural Machinery
Pivoting linkages on harvesters or tillage equipment, where the trunnion mount absorbs misalignment and the 160 mm stroke controls chute or gate positioning.
Material Handling
Swinging diverter gates on heavy-duty conveyors, using the TC mount for the pivot axis and the cylinder's 6136 N force to redirect bulk materials.
Heavy Press Fixtures
Clamping or ejecting large workpieces in stamping presses, where the trunnion allows the cylinder to follow an arc motion under high force.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X160TC the Right Cylinder?
Selecting the SC125X160TC means matching a 125 mm bore, 160 mm stroke, PT port thread, centre trunnion (TC) mount, and no magnet. The TC mount, supplied with the TCM1 bracket (F-SC125TC), allows the cylinder to swing for pivoting loads. For a step down in force, the SC100 bore provides 3927 N at 0.5 MPa; for more force, the SC160 offers 10053 N. At this stroke, ensure the rod is supported against side loads—consider an external guide if the load is not purely axial.
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 SC125X160TC FAQ
At the standard maximum operating pressure of 0.9 MPa, the push force is 11045 N. At a typical plant pressure of 0.5 MPa, it delivers 6136 N pushing and 5734 N pulling (retracting). The theoretical maximum at 1.0 MPa is 1251 kgf.
No. The SC is a tie-rod cylinder and is physically shorter than an ISO 15552 profile cylinder. It is not dimensionally interchangeable. Only replace with another AirTAC SC series cylinder matching the 125 mm bore, 160 mm stroke, PT ports, and TC trunnion mount.
