About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X650
The SC160X650 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, delivering a substantial push force of 10053 N at 0.5 MPa (18095 N at the 0.9 MPa maximum operating pressure). With a 160 mm bore and a 650 mm stroke, this model handles heavy linear actuation tasks while remaining shorter in overall length than an equivalent ISO 15552 cylinder.
Built with a 40 mm diameter piston rod and PT3/4 ports, the cylinder features a 29 mm adjustable air cushion at each end to decelerate the piston smoothly. The body length A is 239 mm, giving a total extended length of approximately 889 mm. Standard TPU seals provide an operating temperature range of -20 to +70 °C.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X650 Is Used
Heavy Material Handling
The 10053 N push force at 0.5 MPa makes the SC160X650 ideal for lifting, tilting, or transferring heavy pallets and steel components in industrial material handling systems.
Agricultural Machinery
Deploy this cylinder in large-scale agricultural equipment for functions like chute positioning, gate control on silos, or actuating heavy folding mechanisms on tillage tools.
Press & Clamping Fixtures
With 18095 N of force available at 0.9 MPa, the SC160X650 provides the high clamping pressure needed for heavy-duty welding fixtures, forming presses, and industrial compactors.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X650 the Right Cylinder?
For applications requiring slightly less force, the SC125 bore offers 6136 N push at 0.5 MPa. If higher force is needed, stepping up to the SC200 bore provides 15708 N at the same pressure. At a 650 mm stroke, the 40 mm rod is robust, but any significant side loading should be managed with an external guide or linear bearing to protect the rod bearing and piston seals from premature wear.
When replacing an existing cylinder, match five key points: 160 mm bore, 650 mm stroke, PT3/4 port thread, the specific mounting accessory (this basic model has none, but confirm if your application uses LB, FA, FB, CA, CB, or TC mounts), and the magnet option (this model has no built-in magnet).
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 SC160X650 FAQ
At the standard 0.5 MPa operating pressure, the push force is 10053 N and the pull force is 9425 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 18095 N. The theoretical maximum force at 1.0 MPa is 2050 kgf.
No. The SC160X650 is a standard double-acting cylinder and will drift or drop if air pressure is lost or the directional valve is centered. The adjustable air cushion only decelerates the piston at the end of stroke; it does not lock or hold the load. For load holding, you must add an external rod brake, a mechanical lock, or a pilot-operated check valve.
