About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X1050
The AirTAC SC160X1050 is a double-acting tie-rod cylinder delivering a substantial 10053 N of push force at 0.5 MPa, scaling to 18095 N at the maximum operating pressure of 0.9 MPa. With a 40 mm diameter piston rod and a 1050 mm stroke, this model is engineered for heavy-duty linear tasks requiring significant force over a long travel distance.
This cylinder features a 29 mm adjustable air cushion at each end to decelerate the piston smoothly, reducing impact and vibration. The body length A is 239 mm, making the total extended length approximately 1289 mm. It uses a PT3/4 port and an M36x2 rod thread, suitable for robust mechanical connections.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X1050 Is Used
Heavy Press & Forming
Provides the high force (up to 18095 N) needed for stamping, pressing, or clamping large workpieces in metal forming and composite molding operations.
Large Part Ejection
The long 1050 mm stroke is ideal for ejecting or transferring large, heavy parts from molds or between conveyor stations in automated warehouses.
Structural Testing Rigs
Suitable for material testing machines requiring a sustained, controlled linear force output over a long distance for tension or compression tests.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X1050 the Right Cylinder?
For applications needing slightly less force, consider stepping down to the SC125 bore, which provides 6136 N of push force at 0.5 MPa. For even higher force requirements, the SC200 bore offers 15708 N at the same pressure. When replacing this cylinder, ensure a 5-point match: 160 mm bore, 1050 mm stroke, PT3/4 port thread, basic mounting (no bracket), and no built-in magnet.
Given the stroke length of 1050 mm, be cautious of side loads. The 40 mm rod, while robust, can be subject to bending moments if the load is not guided externally. For applications with any off-axis force, use an external guide rail or rod support to prevent premature seal and bearing wear.
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 SC160X1050 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 SC160X1050 is not designed for unguided side loads. The 40 mm rod can experience bending stress at full extension if the load is not supported. You must use an external linear guide or a guided cylinder variant to absorb any lateral forces and protect the rod bearings and seals.
