About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X1200S
The AirTAC SC160X1200S is a heavy-duty double-acting tie-rod cylinder delivering 10053 N of push force at 0.5 MPa and up to 18095 N at 0.9 MPa. Its 40 mm diameter piston rod and 29 mm adjustable air cushion at each end manage high-inertia loads smoothly across a 1200 mm stroke.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the barrel for non-contact position sensing. The body length A is 239 mm, giving a total extended length of approximately 1439 mm. Operating pressure is 0.15–1.0 MPa with TPU seals rated for -20 to +70 °C.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X1200S Is Used
Sawmill & Timber Processing
Pushes heavy logs through saw blades or positions timber carriages with high force, where the built-in magnet provides reliable end-of-stroke confirmation in dusty environments.
Heavy Agricultural Machinery
Actuates large hopper doors, chutes, or bale handlers on farming equipment, leveraging 18095 N of thrust at 0.9 MPa for demanding outdoor tasks.
Scrap & Recycling Balers
Compacts cardboard, plastics, or metal scrap into dense bales. The 29 mm cushion absorbs the shock of high-speed compaction strokes.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X1200S the Right Cylinder?
For a 160 mm bore, the SC160 provides 10053 N push at 0.5 MPa. If your load requires less force, stepping down to the SC125 bore (6136 N at 0.5 MPa) can reduce air consumption and physical size. For higher force, the SC200 bore offers 15708 N at the same pressure.
When replacing an existing cylinder, match five points: bore (160 mm), stroke (1200 mm), port thread (PT 3/4), mounting accessory (basic, no bracket), and magnet option (-S). At 1200 mm stroke, the long unsupported rod is vulnerable to bending under side load; use an external linear guide or a guided cylinder if the load is not perfectly axial.
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 SC160X1200S 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, push force reaches 18095 N. The theoretical maximum force at 1.0 MPa is 2050 kgf.
Yes. The -S suffix in SC160X1200S indicates a built-in magnetic piston, so you can use AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors clamped to the barrel. Without the -S option, the standard piston is non-magnetic and sensors cannot detect it.
