About the Airtac SC80 Standard Cylinder SC80X850
The SC80X850 is a double-acting tie-rod cylinder delivering 2513 N of push force at 0.5 MPa, scaling up to 4523 N at the maximum operating pressure of 0.9 MPa. With an 80 mm bore and an 850 mm stroke, this model is well-suited for medium-to-long linear movements in material handling or pressing applications where a substantial force is required.
This cylinder features a 25 mm diameter piston rod and an adjustable air cushion length of 28 mm to decelerate the piston smoothly at each end of the stroke. The total extended body length is approximately 1032 mm, combining the 182 mm body length A with the 850 mm stroke. Standard PT1/8 ports and TPU seals with a -20 to +70 C operating range are fitted.

Where the Airtac SC80 Standard Cylinder SC80X850 Is Used
Pallet Transfer
Pushes heavy pallets across roller conveyors in distribution centers, leveraging the 2513 N push force at standard shop air pressure.
Press-Fit Assembly
Provides the controlled 4523 N force at 0.9 MPa needed to press bearings or bushings into housings on an automated assembly line.
Baler Compression
Drives the compression plate in small-to-medium recycling balers, using the long 850 mm stroke to compact cardboard or plastics.
Is the Airtac SC80 Standard Cylinder SC80X850 the Right Cylinder?
Select the SC80 bore when your application requires a push force between 2513 N and 4523 N. For lower force requirements, stepping down to the SC63 bore provides 1559 N at 0.5 MPa; for significantly higher demands, the SC100 bore offers 3927 N at the same pressure. Always match the bore, stroke, PT port thread, and basic mounting when replacing an existing unit.
With an 850 mm stroke, the piston rod is extended significantly. To prevent rod bending or uneven seal wear, ensure the load is guided externally and that side forces are eliminated. For applications with inherent side load, pairing this cylinder with an external guide rail or selecting a guided cylinder is strongly recommended.
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 SC80X850 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.
An 850 mm stroke on an 80 mm bore cylinder requires careful load alignment. The load must be guided externally on rails or rods to prevent any side load from reaching the cylinder's rod bearing. For unsupported loads, consider using an external guide unit or switching to a guided cylinder configuration.
