About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X300TC
The SC125X300TC is a double-acting pneumatic cylinder delivering 6136 N push force at 0.5 MPa and up to 11045 N at 0.9 MPa, making it a powerful actuator for heavy industrial tasks. This model features a 125 mm bore, 300 mm stroke, and a 32 mm piston rod with M27x2 thread, equipped with an adjustable air cushion (28 mm length) to decelerate end-of-stroke impact.
Supplied as a centre-trunnion variant, the TC mount (with included TCM1 bracket, order code F-SC125TC) allows the cylinder to pivot, ideal for swinging or articulating loads. The body length A is 203 mm, and the total extended length is approximately 503 mm. This genuine AirTAC cylinder uses standard PT threads and TPU seals rated for -20 to +70 °C.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X300TC Is Used
Heavy Press & Clamping
The 11045 N thrust at 0.9 MPa powers heavy-duty clamping fixtures, punch presses, and riveting stations where high force in a compact stroke is essential.
Pivoting Conveyor Gates
With the TC centre trunnion mount, this cylinder smoothly actuates pivoting diverter gates or chutes on conveyor lines, handling heavy material flow.
Industrial Lift & Tilt
Provides 5734 N pull force at 0.5 MPa for tilting heavy bins or lifting scissor mechanisms, with the trunnion absorbing rotational movement.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X300TC the Right Cylinder?
Choose the SC125 bore when your application needs 6136 N of push force at 0.5 MPa. If your load is lighter, stepping down to the SC100 bore provides 3927 N, reducing air consumption and physical size. For a 300 mm stroke, ensure the rod is supported against side loads; an external guide or guided cylinder is recommended to prevent rod bending and premature bearing wear on this ISO 6430 class cylinder.
For direct replacement, match five points: 125 mm bore, 300 mm stroke, PT port thread, centre trunnion (TC) mounting, and the absence of a magnet. This model is a tie-rod cylinder and is not dimensionally interchangeable 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 SC125X300TC FAQ
At 0.5 MPa, 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 reaches 11045 N. The theoretical maximum at 1.0 MPa is 1251 kgf.
No. The SC125X300TC is a double-acting cylinder and will not hold position if pressure is lost or the valve is centered. For load holding, you must add an external rod lock, brake, or a pilot-operated check valve.
