About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X200STC
The AirTAC SC160X200STC is a heavy-duty double-acting tie-rod cylinder engineered for substantial linear force applications. With a 160 mm bore and 200 mm stroke, it generates a push force of 10053 N at 0.5 MPa and a formidable 18095 N at the maximum operating pressure of 0.9 MPa, driven by a robust 40 mm diameter piston rod.
This model features a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors and a centre trunnion (TC) mount, supplied with the TCM1 bracket, allowing the cylinder to pivot for swinging loads. The standard PT ports are sized at PT3/4, and the adjustable pneumatic cushion (29 mm length) decelerates the high-inertia piston smoothly, protecting the end caps during rapid cycling.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X200STC Is Used
Heavy Machinery Actuation
Controls chute gates, hopper doors, and deflector plates on agricultural harvesters and earthmoving equipment, leveraging the 18095 N push force at 0.9 MPa and the pivoting TC mount.
Industrial Press Feed
Positions heavy steel plates or dies into stamping presses, where the 40 mm rod resists bending and the adjustable cushion ensures a soft stop under high inertial loads.
Water Treatment Valve Actuation
Operates large butterfly or gate valves in water treatment plants, with the centre trunnion accommodating the arc motion of the valve linkage and the magnet enabling open/closed position sensing.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X200STC the Right Cylinder?
Select the SC160 when your application requires a push force between the SC125 (6136 N at 0.5 MPa) and the SC200 (15708 N at 0.5 MPa). This 200 mm stroke is well within the 1500 mm maximum standard stroke for the 160 bore, ensuring standard availability. The centre trunnion TC mount (F-SC160TC) is ideal for applications where the cylinder body needs to pivot, absorbing misalignment and simplifying linkage design.
For this stroke length, the 40 mm rod provides excellent column strength, but any significant side load must be managed with an external guide system to prevent rod bearing wear and seal failure. For a direct replacement, match the bore, stroke, PT3/4 port thread, TC mounting accessory, and the integrated magnet (-S) sensor compatibility.
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 SC160X200STC FAQ
At 0.5 MPa, the push force is 10053 N and the pull force is 9425 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 18095 N. The theoretical maximum force at 1.0 MPa is 2050 kgf.
No. The SC160 is a standard double-acting cylinder and will drift or drop if pressure is exhausted or the directional valve is centered. For load holding, you must add a pilot-operated check valve or an external mechanical rod brake.
