About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X270STC
The SC160X270STC is a robust double-acting pneumatic cylinder delivering substantial force for heavy-duty industrial automation. At 0.5 MPa, it provides 10053 N of push force and 9425 N of pull force, scaling up to 18095 N at the maximum operating pressure of 0.9 MPa, driven by a 40 mm diameter piston rod.
This specific configuration includes a built-in magnet (-S) for mounting CMSG/DMSG/EMSG sensors directly onto the tie-rod barrel, and a centre trunnion mount (TC) supplied with the TCM1 bracket, allowing the cylinder to pivot for swinging loads. With a 270 mm stroke and 29 mm adjustable air cushion, it decelerates high-inertia loads effectively, making it a reliable actuator sourced from genuine AirTAC stock.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X270STC Is Used
Palletizer Pushers
The 10053 N push force at 0.5 MPa easily drives heavy palletizing arms to stack bags or boxes, with the trunnion mount allowing the cylinder to pivot smoothly through the pushing arc.
Heavy-Duty Clamping
Ideal for weld fixtures or assembly jigs requiring up to 18095 N of clamping force. The integrated magnet enables end-of-stroke confirmation to ensure the part is secured before the cycle starts.
Transfer Car Drives
Provides the high thrust needed to move heavy transfer cars or shuttle tables. The adjustable cushion decelerates the 40 mm rod smoothly, protecting the structure from impact at the end of the 270 mm travel.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X270STC the Right Cylinder?
Select the SC160 when your application requires force in the 10053 N range at standard plant pressure. For a lighter, more compact solution, step down to the SC125 bore, which offers 6136 N of push force at 0.5 MPa. To ensure a successful replacement, match five key points: the 160 mm bore, 270 mm stroke, PT port thread, centre trunnion (TC) mounting, and the integrated magnet for sensor compatibility. For this 270 mm stroke, ensure the rod is guided if any side load is present, as the 40 mm rod can experience bending moments under off-axis forces.
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 SC160X270STC FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder generates a theoretical push force of 14074 N and a pull force of 13195 N on the retract stroke, considering the 40 mm piston rod area.
Yes, the 'TC' suffix indicates it is configured with a centre trunnion mount, supplied with the TCM1 bracket. This allows the cylinder body to pivot, making it suitable for applications where the load moves through an arc.
