About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X275S
The AirTAC SC160X275S is a double-acting tie-rod cylinder with a 160 mm bore and 275 mm stroke, factory-equipped with a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors. At 0.5 MPa air pressure it generates 10053 N pushing force and 9425 N pulling force, placing it in the 10 kN class for medium-heavy industrial actuation.
This model uses a 40 mm diameter piston rod with M36x2 knuckle threads and PT3/4 ports. The adjustable air cushion (29 mm length) decelerates the 275 mm stroke smoothly, while the TPU seals maintain reliable operation from -20 to +70 °C. The body length A is 239 mm, giving a total extended length of approximately 514 mm.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X275S Is Used
Pallet Transfer & Stopping
The 10 kN push force at 0.5 MPa is ideal for transferring heavy pallets or stopping them at conveyor stations in material handling lines.
Press & Clamping Fixtures
Delivers up to 18095 N at 0.9 MPa for pneumatic clamping and light press-fit operations, with sensor confirmation via the built-in magnet.
Heavy-Duty Gate & Damper Actuation
Robust 40 mm rod and tie-rod construction suit repetitive cycling of hopper gates, diverter chutes, and large HVAC dampers.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X275S the Right Cylinder?
Choose the SC160 bore when your application needs roughly 10 kN of force at standard 0.5 MPa shop air. If you can accept lower force in a smaller envelope, stepping down to the SC125 bore provides 6136 N push at 0.5 MPa. For higher thrust, the SC200 bore delivers 15708 N at the same pressure.
For a 275 mm stroke, ensure the rod is not subjected to significant side loading; long unsupported rods can bend under lateral force. If side loads are unavoidable, use an external linear guide or switch to a guided cylinder. When replacing an existing unit, match five attributes: 160 mm bore, 275 mm stroke, PT3/4 port thread, the built-in magnet (-S), and the basic (no bracket) mounting configuration.
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 SC160X275S FAQ
At 0.5 MPa the push force is 10053 N and pull force is 9425 N. At 0.7 MPa push rises to 14074 N, and at the maximum operating pressure of 0.9 MPa it reaches 18095 N. The theoretical maximum at 1.0 MPa is 2050 kgf.
Yes. The -S suffix indicates a built-in magnet in the piston, so AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors can be clamped directly onto the barrel for end-of-stroke or mid-stroke position sensing.
