About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X450
The AirTAC SC160X450 is a double-acting single-rod tie-rod cylinder built for heavy-duty linear actuation. With a 160 mm bore and 450 mm stroke, it generates a push force of 10053 N at 0.5 MPa and up to 18095 N at the maximum operating pressure of 0.9 MPa, making it suitable for pressing, clamping, and material handling tasks requiring substantial force.
This model features a 40 mm diameter piston rod with an M36x2 knuckle thread and PT3/4 port connections. The adjustable pneumatic cushion is set at 29 mm to decelerate the piston smoothly at stroke end. The body length A measures 239 mm, resulting in a total extended length of approximately 689 mm. Standard TPU seals provide an operating range of -20 to +70 °C.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X450 Is Used
Heavy Pressing & Clamping
Generates up to 18095 N at 0.9 MPa for assembly presses, forming dies, and heavy-duty clamping fixtures requiring high force in a tie-rod package.
Material Handling & Lifting
Provides the muscle for bin tippers, hopper gates, and lift-assist devices in warehouses, using its 450 mm stroke to move heavy loads smoothly.
Sawmill & Wood Processing
Delivers the 10053 N push at 0.5 MPa needed for log stops, board flippers, and carriage drives in dusty sawmill environments where tie-rod cylinders excel.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X450 the Right Cylinder?
Select the SC160X450 when your application demands force in the 10000 N class at standard plant pressure. If you need a more compact option with slightly lower force, the SC125 bore delivers 6136 N push at 0.5 MPa. For even higher force requirements, the SC200 bore provides 15708 N at the same pressure. Always match replacement cylinders by bore, stroke, PT port thread, and basic mounting. For this 450 mm stroke, ensure the 40 mm rod is adequately supported against side loads; if the load is not perfectly guided, consider adding an external guide rail or switching to a guided cylinder to prevent rod bearing wear and bending.
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 SC160X450 FAQ
At 0.5 MPa (5 bar), the push force is 10053 N and the pull force is 9425 N. At the maximum operating pressure of 0.9 MPa, push force increases to 18095 N. The theoretical maximum force at 1.0 MPa is 2050 kgf.
No. The SC160X450 is a double-acting cylinder and will not hold its position if pressure is exhausted or the directional valve is centered. The piston will drift or drop under load. For static load holding without live pressure, you must add a pilot-operated check valve or an external mechanical rod brake.
