About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X300S
The SC160X300S is a double-acting pneumatic cylinder delivering substantial force in a compact tie-rod body. With a 160 mm bore, it generates 10053 N pushing force at 0.5 MPa and up to 18095 N at the maximum operating pressure of 0.9 MPa, making it suitable for heavy pressing, clamping, and lifting tasks.
This model includes a 300 mm stroke, well within the 1500 mm maximum standard stroke for this bore. The built-in magnet (denoted by the -S suffix) allows direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for reliable end-of-stroke detection. It features a 40 mm diameter piston rod with M36x2 threads, PT3/4 ports, and an adjustable air cushion (29 mm length) to decelerate high-inertia loads smoothly.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X300S Is Used
Heavy-Duty Pressing
Generates up to 18095 N of force at 0.9 MPa for stamping, riveting, or forming operations in metal fabrication cells.
Pallet Lifting & Transfer
Provides the high push force needed to lift and transfer heavy pallets or engine blocks between conveyor lines, with magnetic sensors confirming full extension.
Automated Clamping Fixtures
Delivers consistent clamping force for large workpieces on CNC machining centres, with position feedback from barrel-mounted sensors ensuring cycle safety.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X300S the Right Cylinder?
Choose the SC160 bore when your application requires push forces above 10000 N at standard shop air pressure. If your load is lighter, stepping down to the SC125 bore (6136 N push at 0.5 MPa) can reduce air consumption and physical size. For strokes of 300 mm or more, always evaluate side-load conditions; an unsupported 40 mm rod extending 300 mm can experience bending under off-axis forces. In such cases, couple the cylinder with an external linear guide or consider a guided cylinder variant.
To ensure a direct replacement, match five key specifications: 160 mm bore, 300 mm stroke, PT3/4 port thread, the built-in magnet sensor compatibility, and the basic (no bracket) mounting configuration. This SC series tie-rod cylinder is dimensionally shorter than an ISO 15552 profile cylinder and is not interchangeable with that standard.
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 SC160X300S FAQ
At the standard operating pressure of 0.5 MPa, the cylinder provides 10053 N pushing force and 9425 N pulling force. At the maximum operating pressure of 0.9 MPa, the pushing force increases to 18095 N. The theoretical maximum force at 1.0 MPa is 2050 kgf.
No. The SC160X300S is a double-acting cylinder that requires continuous air pressure to maintain its position. If pressure is lost, exhausted, or the directional valve is centred, the piston rod will drift or drop under load. For load-holding applications, you must add an external rod brake, a mechanical lock, or a pilot-operated check valve.
