About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X330
The AirTAC SC160X330 is a double-acting tie-rod cylinder delivering 10053 N of push force at 0.5 MPa, rising to 18095 N at the maximum operating pressure of 0.9 MPa. This model combines a 160 mm bore with a 330 mm stroke, giving an extended body length of approximately 569 mm, making it a robust choice for heavy linear actuation tasks.
Built with a 40 mm diameter piston rod and PT3/4 ports, the SC160X330 includes an adjustable pneumatic cushion (29 mm length) at both ends to decelerate the piston smoothly. The standard TPU seals provide a reliable operating temperature range of -20 to +70 °C, suitable for general industrial environments.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X330 Is Used
Heavy Press Tool Actuation
Provides the high clamping and pressing forces needed for forming, stamping, or riveting operations in heavy manufacturing cells, utilizing its 18095 N thrust at 0.9 MPa.
Pallet Lift and Transfer
Delivers the 10053 N push force at 0.5 MPa required to elevate and transfer heavy pallets or engine blocks between conveyor lines in automated logistics and assembly systems.
Industrial Valve Actuation
Operates large quarter-turn valves or slide gates in processing plants, where the robust 40 mm rod and tie-rod construction provide the necessary stiffness and force for reliable cycling.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X330 the Right Cylinder?
Select the SC160X330 when your application requires substantial force in the 10 kN class at standard plant air pressure. If your force requirement is slightly lower, consider stepping down to the SC125 bore, which provides 6136 N of push force at 0.5 MPa in a more compact package. For even higher force demands, the SC200 bore offers 15708 N at the same pressure.
For this 330 mm stroke, ensure the load is guided and side forces are minimal. Long unsupported strokes with a heavy load can create a bending moment on the 40 mm rod, leading to premature bearing wear. Use external guide rails or a guided cylinder configuration to absorb side loads and protect the rod bearings. When replacing this cylinder, match the bore, stroke, PT port thread, basic mounting, and the absence of a magnet to ensure drop-in 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 SC160X330 FAQ
At 0.7 MPa operating pressure, the SC160 bore generates a theoretical push force of 14074 N. The pull force on the retract stroke is 9425 N at 0.5 MPa; for the exact pull force at 0.7 MPa, confirm from the datasheet, as it is reduced by the rod area.
No. The SC160X330 is a 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 end of stroke to reduce impact. To hold a load safely without live pressure, you must add a pilot-operated check valve or an external mechanical rod brake.
