About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X450TC
The AirTAC SC125X450TC is a double-acting tie-rod cylinder delivering 6136 N of push force at 0.5 MPa and up to 11045 N at the maximum operating pressure of 0.9 MPa. With a 125 mm bore and a 450 mm stroke, this model is built for heavy-duty linear applications requiring substantial force over a medium travel distance. The 32 mm diameter piston rod and 28 mm adjustable air cushion at each end provide robust guidance and smooth deceleration.
This specific configuration includes a centre trunnion mount (TC), supplied with the TCM1 bracket, allowing the cylinder to pivot during operation for swinging or articulating loads. The body length A is 203 mm, giving a total extended length of approximately 653 mm. Operating on filtered air from 0.15 to 1.0 MPa, it uses standard PT ports and TPU seals for a temperature range of -20 to +70 °C.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X450TC Is Used
Conveyor Diverter Gates
The 450 mm stroke and high force capacity actuate heavy diverter gates on mining or aggregate conveyors, reliably redirecting bulk material flow.
Press-Fit Assembly
Delivers up to 11045 N of force for pressing bearings, bushings, or pins into heavy castings, with the trunnion mount allowing the cylinder to self-align.
Agricultural Implement Control
Controls the angle of large tillage tools or harvester headers, pivoting smoothly on the centre trunnion to follow ground contours.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X450TC the Right Cylinder?
Select the SC125 bore when your application requires a push force between roughly 6136 N and 11045 N. If your load is lighter, stepping down to an SC100 bore reduces air consumption while still providing 3927 N at 0.5 MPa. For strokes of 450 mm, always check for side loads; an unsupported 32 mm rod at this extension can be damaged by bending moments. Use an external guide rail or a guided cylinder if lateral forces are present.
To replace an existing cylinder, match five key points: the 125 mm bore, 450 mm stroke, PT port thread, centre trunnion (TC) mounting with the F-SC125TC bracket, and the absence of a magnet. This 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 SC125X450TC 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 force at 1.0 MPa is 1251 kgf.
No. The SC125X450TC is a double-acting cylinder and will drift or drop if pressure is lost or the directional valve is centered. The air cushion only decelerates the piston at the end of stroke; it is not a locking device. For load holding, you must add an external rod brake or a pilot-operated check valve.
