About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X380STC
The AirTAC SC125X380STC is a double-acting pneumatic cylinder delivering 6136 N of push force and 5734 N of pull force at 0.5 MPa. With a 125 mm bore and 380 mm stroke, it provides robust linear motion for medium-to-heavy industrial tasks. The built-in magnet (suffix -S) allows direct mounting of CMSG/DMSG/EMSG sensors for precise position feedback, and the TC suffix supplies the cylinder with a centre trunnion pivot and TCM1 bracket for swinging-load applications.
This ISO 6430 class cylinder uses a 32 mm piston rod with M27x2 threads and PT1/2 ports. The adjustable air cushion (28 mm length) decelerates the piston smoothly at stroke ends. Operating pressure ranges from 0.15 to 1.0 MPa, with a maximum theoretical force of 1251 kgf at 1.0 MPa. The body length A is 203 mm, making the total extended length approximately 583 mm.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X380STC Is Used
Conveyor Diverters
The 6136 N push force at 0.5 MPa and 380 mm stroke effectively operate heavy-duty diverter gates on wide conveyor lines, sorting pallets or large packages with reliable speed.
Press-Fit Assembly
Delivers up to 11045 N at 0.9 MPa for pressing bearings or bushings into heavy housings. The trunnion mount allows the cylinder to pivot, accommodating slight misalignments during the press cycle.
Hopper Gate Actuation
Controls the discharge gate on large aggregate or grain hoppers. The adjustable cushion manages the high inertial load of the gate at the end of the 380 mm stroke, preventing shock damage.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X380STC the Right Cylinder?
The SC125 bore is a step up from the SC100 (3927 N push at 0.5 MPa), offering a 56% force increase for heavier payloads. If your application requires less force, stepping down to the SC100 reduces air consumption and physical size. For strokes of 300 mm or longer, like this 380 mm unit, always evaluate side-load conditions—the 32 mm rod can experience bending stress under lateral forces. Use an external guide rail or a guided cylinder if side loads are present.
To ensure a correct drop-in replacement, match five key points: 125 mm bore, 380 mm stroke, PT1/2 port thread, centre trunnion (TC) mounting with TCM1 bracket (part code F-SC125TC), and the built-in magnet (-S) for sensor compatibility. This is a tie-rod cylinder and will not interchange with ISO 15552 profile cylinders.
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 SC125X380STC FAQ
At the standard 0.5 MPa operating pressure, the push force is 6136 N and the pull force is 5734 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 11045 N. The theoretical maximum at 1.0 MPa is 1251 kgf.
No. The SC125X380STC is a double-acting cylinder that requires continuous air pressure to maintain position. If pressure is lost or the directional valve is centered, the piston can drift or drop. For load-holding applications, you must add a pilot-operated check valve or an external mechanical rod lock.
