About the Airtac SC80 Standard Cylinder SC80X630
The SC80X630 is a double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa and up to 4523 N at 0.9 MPa. With an 80 mm bore and a 630 mm stroke, it uses a 25 mm diameter piston rod and PT3/8 ports, making it a strong mid-range actuator for industrial linear motion.
This tie-rod cylinder includes an adjustable air cushion (28 mm length) at both ends to decelerate the piston smoothly, reducing end-of-stroke impact. The body length A is 182 mm, giving a total extended length of approximately 812 mm. It operates on filtered air from 0.15 to 1.0 MPa within a -20 to +70 °C temperature range using standard TPU seals.

Where the Airtac SC80 Standard Cylinder SC80X630 Is Used
Material Handling Gates
Operates diverter gates and flow-control flaps on conveyors, using its 630 mm stroke to fully open or close material paths in bulk handling systems.
Clamping & Fixturing
Applies 2513 N of clamping force at standard line pressure to secure large workpieces during welding, assembly, or machining operations.
Agricultural Machinery
Powers the motion of sorting arms and bin-tipping mechanisms on harvesters and packing lines, with the long stroke providing the necessary reach.
Is the Airtac SC80 Standard Cylinder SC80X630 the Right Cylinder?
For applications needing slightly less force, consider stepping down to the 63 mm bore (1559 N at 0.5 MPa). If you require more thrust, the 100 mm bore provides 3927 N at the same pressure. Always match replacement cylinders on five key points: bore, stroke, PT3/8 port thread, basic mounting style, and the absence of a magnet.
At a 630 mm stroke, the 25 mm rod is subject to bending under side loads. For long-stroke applications, evaluate the need for an external guide rail or a guided cylinder to protect the rod bearing and ensure reliable, bind-free operation.
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 SC80X630 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 increases to 4523 N.
No. The SC series is a tie-rod cylinder that is shorter than an ISO 15552 profile cylinder, so it is not dimensionally interchangeable. It directly replaces another AirTAC SC80 cylinder with the same bore, stroke, PT port, and basic mount.
