About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X375
The AirTAC SC125X375 is a double-acting, tie-rod pneumatic cylinder delivering 6136 N of push force at 0.5 MPa and up to 11045 N at the 0.9 MPa maximum operating pressure. With a 375 mm stroke and a 32 mm diameter piston rod, it is built for heavy linear actuation where robust force output and structural rigidity are required.
This ISO 6430 class cylinder features a 28 mm adjustable air cushion at each end to decelerate high-inertia loads smoothly. The body length A is 203 mm, giving a total extended length of approximately 578 mm. The standard PT1/2 port and M27x2 rod thread provide secure, high-flow connections for demanding industrial pneumatic circuits.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X375 Is Used
Heavy Machinery Actuation
Provides the high force needed for lifting, pressing, or shifting heavy components in agricultural and construction equipment, where the 11045 N max thrust handles substantial static and dynamic loads.
Palletising and Packaging
Drives pusher arms and layer-forming mechanisms in palletisers, using the 375 mm stroke to move boxes or bags into position with consistent, repeatable force.
Industrial Pressing & Clamping
Delivers stable clamping force for large-scale welding fixtures or forming presses, where the tie-rod construction withstands high cycle rates and vibration.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X375 the Right Cylinder?
For applications needing slightly less force, stepping down to the SC100 bore reduces push force to 3927 N at 0.5 MPa, while moving up to the SC160 bore increases it to 10053 N. At a 375 mm stroke, ensure the rod is not subjected to significant side loading; long unsupported rods on tie-rod cylinders can bend under lateral forces. For guided motion, pair this cylinder with an external linear guide or consider a guided cylinder assembly.
When replacing an existing unit, match five critical points: 125 mm bore, 375 mm stroke, PT1/2 port thread, any mounting accessory (this is a basic body, so confirm your bracket part number), and the presence or absence of a magnet. This model has no built-in magnet, so external sensor mounting is required if position feedback 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 SC125X375 FAQ
At 0.5 MPa, the push force is 6136 N and the pull force is 5734 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 11045 N. The theoretical maximum force at 1.0 MPa is 1251 kgf.
No. The SC series is a tie-rod cylinder that is physically shorter than an ISO 15552 profile cylinder. The 125 mm bore is classified as ISO 6430 class. It is a direct dimensional replacement only for another AirTAC SC125 tie-rod cylinder with the same stroke, port type, and mounting configuration.
