About the Airtac SC80 Standard Cylinder SC80X245
The AirTAC SC80X245 is a robust double-acting tie-rod cylinder delivering 2513 N of push force at 0.5 MPa (4523 N at 0.9 MPa). With an 80 mm bore and a 245 mm stroke, it uses a 25 mm diameter piston rod and PT3/8 ports, making it a strong mid-range actuator for general industrial automation.
This model features a 28 mm adjustable air cushion at each end to decelerate the piston smoothly, reducing end-of-stroke impact. The total extended body length is approximately 427 mm (182 mm body length A plus the 245 mm stroke), providing a compact yet powerful solution for pushing, pressing, and clamping tasks.

Where the Airtac SC80 Standard Cylinder SC80X245 Is Used
Material Transfer
Pushes boxes or pallets off a conveyor line with 2513 N of force at 0.5 MPa, ideal for medium-weight sorting and diverting stations.
Assembly Pressing
Provides up to 4523 N at 0.9 MPa for pressing bearings, bushings, or pins into housings in automated assembly cells.
Clamping & Fixturing
Holds workpieces securely during machining or welding, using the 28 mm cushion to gently contact parts without impact damage.
Is the Airtac SC80 Standard Cylinder SC80X245 the Right Cylinder?
Choose the SC80X245 when your application needs around 2500 N of force at standard plant air pressure. If you require less force, the SC63 series offers 1559 N at 0.5 MPa; for heavier loads, the SC100 series steps up to 3927 N. Always match the bore, 245 mm stroke, PT3/8 port thread, and basic mounting when replacing an existing cylinder.
For this 245 mm stroke, ensure the load is guided and axial to prevent side-load bending on the 25 mm rod. If side loads are unavoidable, use an external guide rail or switch to a guided cylinder to protect the rod bearing and seals from premature 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 SC80 Standard Cylinder SC80X245 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, push force reaches 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf.
No. The SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 profile cylinder, so mounting dimensions and body length will differ. Only use it to replace another AirTAC SC80 tie-rod cylinder with matching bore, stroke, PT3/8 ports, and basic mounting.
