About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X400STC
The AirTAC SC160X400STC is a robust double-acting pneumatic cylinder delivering substantial force for heavy-duty industrial applications. With a 160 mm bore and 400 mm stroke, it generates a 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 ideal for pressing, clamping, and material handling tasks requiring high thrust.
This model features a 40 mm diameter piston rod with an M36x2 knuckle thread and a 29 mm adjustable air cushion at each end to decelerate high inertial loads smoothly. The built-in magnet allows direct mounting of CMSG/DMSG/EMSG sensors, while the centre trunnion (TC) mount, supplied with the TCM1 bracket, enables the cylinder to pivot for swinging load applications.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X400STC Is Used
Heavy Press Operations
Delivers up to 18095 N of force for stamping, forming, and assembly presses in automotive and metalworking lines.
Material Handling
Pivots and transfers heavy pallets or steel components on conveyors using the centre trunnion mount for smooth angular motion.
Swinging Gate Actuation
Operates large industrial gates or dampers, with the TC mount allowing the cylinder body to swing as the gate opens and closes.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X400STC the Right Cylinder?
For applications needing a centre pivot mount and sensor feedback, the SC160X400STC is the correct choice. If your load requires even higher force, stepping up to the SC200 bore provides 28274 N of push at 0.9 MPa. For long strokes like 400 mm, ensure the rod is externally guided if significant side loads are present, as the 40 mm rod, while strong, can be subject to bending under off-axis forces. When replacing, match bore, 400 mm stroke, PT port thread, TC mount with TCM1 bracket, and the -S magnet option exactly.
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 SC160X400STC FAQ
At 0.7 MPa (7 bar) air pressure, the SC160X400STC cylinder produces a theoretical push force of 14074 N on the piston extension stroke.
The TC centre trunnion position is fixed at the factory and is not designed to be slid along the barrel. It is supplied as a set with the TCM1 bracket for direct pivoting installation.
