About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X270S
The SC160X270S is a double-acting pneumatic cylinder delivering 10053 N of push force at 0.5 MPa and up to 18095 N at 0.9 MPa, making it a heavy-duty actuator for industrial machinery. With a 270 mm stroke and a 40 mm diameter piston rod, it provides robust linear motion for pressing, clamping, and lifting applications.
This model features a built-in magnet, allowing easy attachment of CMSG, DMSG, or EMSG reed and solid-state sensors directly to the tie-rod barrel for precise position feedback. The adjustable air cushion at each end decelerates the piston smoothly, and the PT3/4 port threads ensure high flow for rapid cycling.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X270S Is Used
Heavy Press Frames
Generates up to 18095 N of force for stamping, forming, or assembly presses requiring consistent, high-pressure linear actuation.
Pallet Lifting Stations
Lifts and positions heavy pallets or containers on automated lines, with sensor feedback confirming full extension and retraction.
Material Handling Pushers
Pushes heavy components or rejects off a conveyor, using the built-in magnet for end-of-stroke detection to sequence downstream equipment.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X270S the Right Cylinder?
Select the SC160 when your application requires forces in the 10000-18000 N range. If you need less force, the SC125 bore provides 6136 N at 0.5 MPa; for higher force, step up to the SC200 at 15708 N. For this 270 mm stroke, ensure the load is guided if side forces are present, as the 40 mm rod can experience bending moments under off-axis loads. To replace an existing cylinder, match the 160 mm bore, 270 mm stroke, PT3/4 port, basic mount, and the -S magnet option.
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 SC160X270S 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.
Yes. The -S suffix indicates a built-in magnet along the barrel, which is compatible with AirTAC CMSG, DMSG, and EMSG series sensors for non-contact position sensing.
