About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X625STC
The AirTAC SC160X625STC is a double-acting single-rod pneumatic cylinder delivering substantial force for heavy-duty industrial automation. With a 160 mm bore, it generates 10053 N of push force at 0.5 MPa and reaches 18095 N at the maximum operating pressure of 0.9 MPa, driven by a robust 40 mm diameter piston rod.
This 625 mm stroke model features a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, enabling precise end-of-stroke detection. It comes equipped with a centre trunnion mount (TC suffix) including the TCM1 bracket (F-SC160TC), allowing the cylinder to pivot for swinging load applications. The adjustable pneumatic cushion (29 mm length) decelerates the piston smoothly, protecting the end caps from impact.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X625STC Is Used
Heavy Part Clamping
The 18095 N clamping force at 0.9 MPa securely holds large weldments or castings during machining, with sensor confirmation via the built-in magnet.
Pallet Lift & Transfer
Centre trunnion mount allows the cylinder to pivot while lifting heavy pallets, with the 625 mm stroke providing the necessary vertical travel.
Press Tool Actuation
Delivers consistent, high-force linear motion for pressing bearings or forming sheet metal, with adjustable cushioning to soften the return stroke.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X625STC the Right Cylinder?
Select the SC160X625STC when your application requires a push force between roughly 628 N (SC40) and 3927 N (SC100) at 0.5 MPa, stepping up to this 160 mm bore for its 10053 N capability. For even higher loads, the SC200 bore provides 15708 N at the same pressure. Always match replacements on all five key points: 160 mm bore, 625 mm stroke, PT port thread, centre trunnion (TC) mounting, and the built-in magnet (-S) for sensor compatibility.
With a 625 mm stroke, the extended 40 mm rod is susceptible to bending under side loads. For applications where the load is not perfectly guided and linear, install an external guide rail or consider a guided cylinder variant to prevent rod bearing damage and ensure long service life.
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 SC160X625STC FAQ
At 0.7 MPa (roughly 100 psi), the theoretical push force is 14074 N. At the maximum operating pressure of 0.9 MPa, it reaches 18095 N. The pull force on the retract stroke is slightly lower due to the 40 mm rod area, delivering 9425 N at 0.5 MPa.
No. The SC160X625STC is a standard double-acting cylinder and will not hold position if air pressure is exhausted or the directional valve is centered. The piston will drift or the load will drop. You must add a pilot-operated check valve or an external mechanical rod lock for static load holding.
