About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X270
The SC160X270 is a robust double-acting pneumatic cylinder delivering 10053 N of push force at 0.5 MPa, scaling up to a substantial 18095 N at the maximum operating pressure of 0.9 MPa. With a 40 mm diameter piston rod and a 29 mm adjustable air cushion at each end, it is built to decelerate heavy loads smoothly, making it a reliable workhorse for demanding industrial tasks.
This model features a 270 mm stroke within the 1500 mm maximum standard range for the 160 mm bore, providing a total extended body length of approximately 509 mm. The tie-rod construction ensures durability and serviceability, while the standard PT3/4 port and M36x2 rod thread offer secure, high-flow connections for consistent performance.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X270 Is Used
Heavy Press Tool Actuation
Provides the high force (up to 18095 N) needed for clamping, pressing, and punching operations in metal forming and assembly cells.
Pallet Lift & Transfer
Handles heavy pallet lifting and right-angle transfers in logistics and packaging lines, where the 270 mm stroke offers a precise, repeatable vertical shift.
Industrial Gate & Damper Control
Operates large material flow gates and dampers in heavy industries like mining, cement, and waste processing, leveraging its robust tie-rod build and high thrust.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X270 the Right Cylinder?
For applications requiring a different force profile, consider stepping down to the 125 mm bore (6136 N push at 0.5 MPa) for a lighter, more compact solution, or up to the 200 mm bore (15708 N push at 0.5 MPa) for significantly higher force. The 270 mm stroke on a 40 mm rod is well-supported, but always ensure the load is guided and free from side forces to prevent rod bending and premature seal wear. For a direct replacement, match the 160 mm bore, 270 mm stroke, PT3/8 port thread, basic mounting, and confirm the magnet requirement.
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 SC160X270 FAQ
At 0.5 MPa, 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 SC160X270 is a double-acting cylinder and will not hold its position if air pressure is lost or the valve is centered. The piston will drift. For load holding, you must add an external rod lock, a mechanical brake, or a pilot-operated check valve in the circuit.
