About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X950
The SC160X950 is a double-acting tie-rod cylinder delivering a substantial 10053 N of push force at 0.5 MPa, scaling up to 18095 N at the maximum operating pressure of 0.9 MPa. With a 950 mm stroke and a 40 mm diameter piston rod, this model is built for heavy linear tasks requiring a long, powerful reach.
Its 160 mm bore body has a length A of 239 mm, and the adjustable pneumatic cushion (29 mm length) effectively decelerates the piston near the stroke end to protect the end caps. The standard PT3/4 port and M36x2 rod thread ensure a robust connection for demanding industrial tooling.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X950 Is Used
Heavy Pallet Handling
Pushes or pulls loaded pallets onto conveyor spurs in distribution centers, using the 10053 N force at standard shop air to move multi-ton loads reliably.
Industrial Press Feed
Transfers heavy steel sheets or composite panels into a stamping press. The 950 mm stroke clears the press bed, and the adjustable cushion ensures a soft stop.
Log Splitter Actuation
Provides the high-force push for a hydraulic-assisted or direct pneumatic log splitter, leveraging the 18095 N maximum thrust at 0.9 MPa to split dense hardwood.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X950 the Right Cylinder?
For applications needing slightly less force, the 125 mm bore SC125 series provides 6136 N at 0.5 MPa, while the 200 mm bore SC200 steps up to 15708 N. At a 950 mm stroke, ensure the rod is guided externally if significant side loads are present, as the long extension can create a bending moment on the rod bearing. When replacing this cylinder, match five points precisely: 160 mm bore, 950 mm stroke, PT3/4 port thread, the specific mounting accessory (if any), and the magnet option (-S).
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 SC160X950 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 increases to 18095 N. The theoretical maximum force at 1.0 MPa is 2050 kgf.
No, the SC160X950 is a standard double-acting cylinder and will not hold its position if air pressure is lost or the directional valve is centered. The adjustable air cushion only decelerates the piston at the stroke ends; it is not a locking or holding brake. For position holding, you must add an external rod lock or a pilot-operated check valve.
