About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X450TC
The SC160X450TC 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 the maximum operating pressure of 0.9 MPa). With a 40 mm diameter piston rod and a 450 mm stroke, this model is built for heavy-duty industrial applications requiring high force over a medium travel distance.
This configuration includes a centre trunnion (TC) mount, supplied with the TCM1 bracket (F-SC160TC), allowing the cylinder to pivot and absorb misalignment in swinging load applications. The body length A is 239 mm, and the adjustable pneumatic cushion (29 mm) at both ends decelerates the piston smoothly, protecting the end caps from impact damage.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X450TC Is Used
Heavy Machinery Actuation
Provides the high force needed for lifting and tilting mechanisms on construction and agricultural equipment, where the trunnion mount allows the cylinder to follow an arc.
Material Handling Gates
Controls heavy diverter gates or chutes in mining and aggregate processing, using the 10053 N force at 0.5 MPa to move large material flows reliably.
Industrial Press Feed
Powers the feed mechanism on large stamping presses or die-casting machines, delivering a consistent 450 mm stroke with the high thrust required for moving heavy tooling.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X450TC the Right Cylinder?
For applications needing slightly less force, consider stepping down to the 125 mm bore (6136 N push at 0.5 MPa). If your load requires even greater force, the 200 mm bore offers 15708 N at the same pressure. The 450 mm stroke on this 40 mm rod is robust, but always avoid direct side loading; for guided motion, pair the cylinder with an external linear guide.
To ensure a correct replacement, match five key specifications: the 160 mm bore, the 450 mm stroke, the PT3/4 port thread, the TC centre trunnion mounting accessory, and the absence of a built-in magnet. This is a genuine AirTAC SC tie-rod cylinder, which is shorter than a standard ISO 15552 cylinder and is not dimensionally interchangeable with that profile.
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 SC160X450TC FAQ
At the standard operating pressure of 0.5 MPa, the cylinder provides a theoretical push force of 10053 N and a pull force of 9425 N. The maximum push force at 0.9 MPa is 18095 N. The theoretical maximum at 1.0 MPa is 2050 kgf.
Direct replacement requires the same TC centre trunnion mount to maintain the pivot point and stroke alignment. Switching to a foot mount (LB) would change the cylinder's movement arc and mounting interface, requiring a redesign of the machine's bracketry.
