About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X50
The AirTAC SC160X50 is a double-acting pneumatic cylinder delivering substantial force in a compact 50 mm stroke. At 0.5 MPa it provides 10053 N push and 9425 N pull, scaling to 18095 N at the 0.9 MPa maximum operating pressure.
This model features a 40 mm diameter piston rod with M36x2 threads and PT3/4 ports. The tie-rod construction includes an adjustable air cushion (29 mm length) to decelerate the 160 mm bore piston smoothly, and the standard TPU seals suit operating temperatures from -20 to +70 °C.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X50 Is Used
Heavy Press Tool Actuation
Powers short-stroke clamping and pressing fixtures with 10 kN force at 0.5 MPa, ideal for holding workpieces during welding or assembly.
Material Stops and Gates
Deploys a robust stop pin or diverter gate on heavy-duty conveyor lines, using the 50 mm stroke for quick, repeatable positioning of pallets.
Die Cushion Ejection
Provides a powerful, controlled ejection stroke in metal stamping dies, leveraging the adjustable cushion to manage impact at the end of the 50 mm travel.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X50 the Right Cylinder?
For applications needing slightly less force in a similar footprint, the 125 mm bore SC125 series offers 6136 N push at 0.5 MPa. If 50 mm stroke is insufficient, the SC160 supports standard strokes up to 1500 mm. When replacing an existing cylinder, match five points: 160 mm bore, 50 mm stroke, PT3/4 port thread, basic (no bracket) mounting, and confirm whether a magnet (-S) is required for sensors.
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 SC160X50 FAQ
At 0.7 MPa operating pressure, the SC160X50 produces a theoretical push force of 14074 N. The maximum force at 0.9 MPa is 18095 N. Always apply a safety factor for dynamic loads.
Yes, you would order model SC160X50TC, which includes the centre trunnion and TCM1 bracket. The basic SC160X50 model has no mounting accessories; you can add the TC mount or foot (LB), flange (FA/FB), or clevis (CA/CB) brackets separately using the F-SC160 accessory series.
