About the Airtac SC80 Standard Cylinder SC80X125
The SC80X125 is a double-acting tie-rod cylinder delivering 2513 N of push force at 0.5 MPa (up to 4523 N at 0.9 MPa). Its 25 mm diameter piston rod and 28 mm adjustable air cushion make it well-suited for medium-duty linear tasks where a compact body length is required.
With a body length A of 182 mm, this 125 mm stroke model extends to approximately 307 mm overall. It uses PT1/8 ports and operates on filtered air from 0.15 to 1.0 MPa across a temperature range of -20 to +70 °C with its standard TPU seals.

Where the Airtac SC80 Standard Cylinder SC80X125 Is Used
Conveyor Diverting
The SC80X125 provides ample force to actuate gates or pushers on packaging lines, diverting cartons or products reliably at speeds up to 800 mm/s.
Clamping & Fixturing
With 2513 N of force at standard shop air, this cylinder is ideal for robust workpiece clamping in machining or welding fixtures, holding parts securely during operation.
Material Lift Assist
Use the SC80X125 for lifting or tilting medium-weight bins and totes in material handling stations, leveraging its high push force for smooth, controlled motion.
Is the Airtac SC80 Standard Cylinder SC80X125 the Right Cylinder?
Choose the SC80 bore when your application needs between 2513 N and 4523 N of push force. If you require less force, the SC63 bore provides 1559 N at 0.5 MPa in a smaller footprint. For higher force, step up to the SC100 which delivers 3927 N at the same pressure. This 125 mm stroke is within the standard range for the 80 mm bore.
To ensure a correct replacement, match five key points: the 80 mm bore, 125 mm stroke, PT port thread, basic mounting configuration, and the absence of a magnet. The SC series 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 SC80 Standard Cylinder SC80X125 FAQ
At 0.5 MPa, the push force is 2513 N and the pull force is 2268 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 4523 N. The theoretical maximum force at 1.0 MPa is 513 kgf.
No. The SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 cylinder. The mounting dimensions and accessory interfaces are different, so it is not a drop-in replacement. It directly replaces another AirTAC SC80 cylinder with matching specifications.
