About the Airtac SC80 Standard Cylinder SC80X870
The AirTAC SC80X870 is an 80 mm bore, 870 mm stroke double-acting tie-rod cylinder built for linear force applications needing a mid-range thrust. At 0.5 MPa it outputs 2513 N pushing and 2268 N pulling, scaling to 4523 N at the 0.9 MPa maximum operating pressure. The 25 mm diameter piston rod and 28 mm adjustable air cushion at each end help manage end-of-stroke deceleration on this extended-stroke model.
With a body length A of 182 mm, the total extended length reaches approximately 1052 mm. The cylinder uses PT3/8 ports and an M20x1.5 rod thread. Standard TPU seals give an operating temperature range of -20 to +70 °C. This is a genuine AirTAC SC-series cylinder, factory-tested to a 1.5 MPa proof pressure.

Where the Airtac SC80 Standard Cylinder SC80X870 Is Used
Long-Stroke Part Transfer
The 870 mm stroke moves trays or fixtures between distant conveyor stations. The 2513 N push force at 0.5 MPa handles moderate payloads, while the adjustable cushion protects the assembly from hard end-of-travel impacts.
Material Roll Tensioning
Apply consistent 2268 N pull force at 0.5 MPa to maintain tension on paper, film, or textile rolls. The tie-rod construction withstands the continuous cycling common in web-processing lines.
Vertical Lift Gate Actuation
Operate a tall lift gate or hopper door with the 80 mm bore. The 28 mm cushion absorbs the kinetic energy of the moving gate, reducing noise and mechanical shock in busy logistics hubs.
Is the Airtac SC80 Standard Cylinder SC80X870 the Right Cylinder?
Choose the SC80 bore when your application needs between 2513 N and 4523 N of pneumatic force. If you require a more compact unit and can accept less force, the 63 mm bore delivers 1559 N at 0.5 MPa; for heavier loads, the 100 mm bore provides 3927 N at the same pressure. For this 870 mm stroke, side-load management is critical. An unsupported 25 mm rod at full extension is vulnerable to bending under lateral force—add an external linear guide or switch to a guided cylinder if the load is not perfectly axial.
To replace an existing SC80X870, match five points: 80 mm bore, 870 mm stroke, PT3/8 port thread, any mounting accessory (e.g., foot, flange, or trunnion), and whether a magnet is needed for sensors. 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 SC80 Standard Cylinder SC80X870 FAQ
At 0.5 MPa (approx. 73 psi) the cylinder pushes with 2513 N and pulls with 2268 N. At 0.7 MPa, push force rises to 3518 N. The maximum operating pressure of 0.9 MPa delivers 4523 N of push force. The theoretical force at 1.0 MPa is 513 kgf, but the cylinder should not be operated above 1.0 MPa.
No. The SC80X870 is a double-acting cylinder that requires continuous air pressure to maintain position. If pressure is lost or the directional valve is centered, the piston can drift. For load holding without live pressure, you must add an external rod lock, a pilot-operated check valve, or a mechanical brake.
