About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X35
The AirTAC SC125X35 is a robust double-acting tie-rod cylinder engineered for short-stroke, high-force applications. With a 125 mm bore and 35 mm stroke, it generates 6136 N of push force at 0.5 MPa and up to 11045 N at 0.9 MPa, making it suitable for pressing, clamping, and heavy-duty stopping functions.
This model features a 32 mm diameter piston rod with an M27x2 thread, PT1/2 ports, and a 28 mm adjustable air cushion at each end. As part of the ISO 6430 class, it operates within a 30-500 mm/s speed range and uses standard TPU seals for a temperature range of -20 to +70 °C.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X35 Is Used
Heavy-Duty Clamping
The 6136 N force at 0.5 MPa securely holds large workpieces during machining or welding, preventing movement under high loads.
Part Stops and Ejectors
Delivers a powerful, short stroke to stop or divert heavy pallets and components on conveyor lines without requiring a long cylinder.
Press-Fit Assembly
Provides the controlled, high force needed for pressing bearings, bushings, or pins into place in a compact automation cell.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X35 the Right Cylinder?
Select the SC125X35 when you need substantial force in a compact stroke. If your application requires even higher force, consider stepping up to the SC160 bore (10053 N push at 0.5 MPa). For lighter, faster cycling, the SC100 bore delivers 3927 N at 0.5 MPa.
To ensure a direct replacement, match five key specifications: 125 mm bore, 35 mm stroke, PT port thread, the specific mounting accessory (this is a basic model without a bracket), and the absence of a built-in magnet. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC125X35 FAQ
At the standard operating pressure of 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 increases to 11045 N.
No. The AirTAC SC series is a tie-rod cylinder that is shorter in overall length than a comparable ISO 15552 cylinder. It is not dimensionally interchangeable. It is a direct replacement only for another AirTAC SC125 tie-rod cylinder with matching stroke, port thread, and mounting.
