About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X450LT
The AirTAC SC160X450 is a robust 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 40 mm diameter piston rod and a 450 mm stroke, this model is built for heavy industrial tasks requiring significant linear force.
Featuring a 29 mm adjustable air cushion at each end, the SC160X450 effectively decelerates high inertial loads, reducing end-of-stroke impact. The body length A is 239 mm, giving a total extended length of approximately 689 mm. This genuine AirTAC cylinder uses a PT3/4 port and standard TPU seals for reliable operation from -20 to +70 °C.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X450LT Is Used
Heavy Machinery Actuation
Provides the high force needed to lift, tilt, or shift heavy implements on agricultural and construction equipment, operating reliably in dusty conditions.
Pallet Transfer Systems
Pushes heavy pallets or large components weighing up to a tonne across roller conveyors in automated logistics and distribution centers.
Large Part Clamping
Secures massive castings or weldments in heavy fabrication jigs, using 10053 N of force at standard shop air pressure to prevent movement during machining.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X450LT the Right Cylinder?
Selecting the SC160X450 means matching a high-force requirement with a 450 mm stroke. If your application demands even more force, the SC200 series offers a push force of 15708 N at 0.5 MPa. For a step down in size, the SC125 provides 6136 N. At this 450 mm stroke, ensure the 40 mm rod is adequately supported against side loads; for off-center or shifting loads, use an external guide rail or a guided cylinder to prevent rod bending and premature bearing wear. For a direct replacement, match the 160 mm bore, 450 mm stroke, PT3/4 port thread, and confirm if a magnet or mounting accessory is needed.
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 SC160X450LT 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 at 1.0 MPa is 2050 kgf.
No. The SC series is a tie-rod design that is physically shorter than a comparable ISO 15552 cylinder, so it is not dimensionally interchangeable. It is a direct replacement only for another AirTAC SC series cylinder or an equivalent tie-rod cylinder with a 160 mm bore, 450 mm stroke, and PT3/4 ports.
