About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X300STC
The AirTAC SC160X300STC is a double-acting single-rod tie-rod cylinder delivering 10053 N push and 9425 N pull at 0.5 MPa, rising to 18095 N push at the 0.9 MPa maximum operating pressure. With a 300 mm stroke and a 40 mm diameter piston rod, this model is built for heavy linear transfer and pressing tasks where substantial force is non-negotiable.
This variant includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and ships with the TC centre trunnion mount plus TCM1 bracket (F-SC160TC) for pivoting actuation. The 29 mm adjustable air cushion at each end decelerates the 160 mm bore piston smoothly, protecting the end caps during high-cycle operation.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X300STC Is Used
Pallet Lift & Transfer
The 10053 N push force at 0.5 MPa easily raises and transfers heavy pallets or engine blocks between conveyor lines, with the trunnion mount allowing the cylinder to pivot as the lift angle changes.
Heavy-Duty Clamping & Pressing
Delivers up to 18095 N of clamping force at 0.9 MPa for holding large weldments, composite layup tools, or heavy fabrications securely during automated processing.
Foundry & Mill Gate Actuation
Operates heavy slide gates or diverter chutes in foundries and mills. The TPU seals handle standard temperatures, and the magnet allows end-of-stroke confirmation in dusty environments.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X300STC the Right Cylinder?
Choose the SC160 when your application needs roughly 10000 N of force at standard shop air; stepping down to the SC125 bore cuts push force at 0.5 MPa to 6136 N, while moving up to the SC200 bore raises it to 15708 N. The 300 mm stroke is within the 1500 mm maximum standard stroke for this bore.
For a 300 mm stroke, ensure the rod is not subjected to side load; if the load is not guided externally, use an external guide rail or a guided cylinder to prevent rod bending and premature bearing wear. When replacing, match five points exactly: 160 mm bore, 300 mm stroke, PT port thread, TC centre trunnion mounting (F-SC160TC), and the built-in magnet (-S) for sensor compatibility.
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 SC160X300STC FAQ
At 0.5 MPa, the push force is 10053 N and the pull force is 9425 N. At 0.7 MPa, push force increases to 14074 N, and at the maximum operating pressure of 0.9 MPa, it reaches 18095 N.
Yes. The -S suffix in SC160X300STC indicates a built-in magnet, allowing you to clamp CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel for piston position detection.
