About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X160STC
The SC125X160STC is a heavy-duty double-acting pneumatic cylinder delivering 6136 N of push force at 0.5 MPa (11045 N at 0.9 MPa). Its 160 mm stroke and 32 mm diameter piston rod suit industrial tasks requiring substantial force in a compact linear envelope.
This model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors and a centre trunnion (TC) mount with TCM1 bracket for pivoting applications. The adjustable air cushion (28 mm) decelerates the 125 mm bore piston smoothly, protecting end caps during high-cycle operation.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X160STC Is Used
Conveyor Diverter Gates
The 6136 N push force at 0.5 MPa and pivoting trunnion mount reliably actuates heavy diverter gates in material handling lines.
Clamping & Pressing Fixtures
Delivers up to 11045 N at 0.9 MPa for robust workpiece clamping in machining centres and assembly jigs, with sensor feedback confirming clamp position.
Pivoting Machine Guards
The TC centre trunnion and magnet sensor enable controlled, monitored swinging motion of heavy safety guards on large industrial machinery.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X160STC the Right Cylinder?
Choose the SC125 when the SC100’s 3927 N (at 0.5 MPa) is insufficient for your load. For strokes of 300 mm or more, evaluate side-load forces on the 32 mm rod; an external guide or guided cylinder prevents rod bending and premature bearing wear under offset loads.
To replace an existing cylinder, match five points: bore (125 mm), stroke (160 mm), PT port thread, centre trunnion mounting (TC with F-SC125TC bracket), and the magnet option (-S) for sensor compatibility. This tie-rod design is not dimensionally interchangeable with ISO 15552 profiles.
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 SC125X160STC FAQ
At 0.5 MPa, the push force is 6136 N and pull force is 5734 N. At the maximum operating pressure of 0.9 MPa, push force reaches 11045 N. The theoretical maximum at 1.0 MPa is 1251 kgf.
No. The SC125 is a double-acting cylinder and will drift or drop if pressure is exhausted. The adjustable cushion only decelerates the piston at stroke end; it is not a locking device. For load holding without live pressure, add a pilot-operated check valve or external rod brake.
