About the Airtac SC80 Standard Cylinder SC80X647
The AirTAC SC80X647 is a double-acting tie-rod cylinder with an 80 mm bore and a non-standard 647 mm stroke, made to order for applications needing a precise extended length. At 0.5 MPa it generates 2513 N pushing force and 2268 N pulling force, while at the maximum operating pressure of 0.9 MPa the thrust reaches 4523 N, making it a powerful mid-range linear actuator.
This model features a 25 mm diameter piston rod with an M20x1.5 knuckle thread and PT3/8 pneumatic ports. The total extended body length is approximately 829 mm (182 mm body length A plus the 647 mm stroke). An adjustable air cushion at each end, with a 28 mm cushion length, decelerates the piston smoothly without locking the load.

Where the Airtac SC80 Standard Cylinder SC80X647 Is Used
Belt Tensioning
Provides the sustained 2513 N force needed to tension heavy conveyor belts in mining or bulk material handling, with the 647 mm stroke accommodating large take-up distances.
Press-Fit Assembly
Delivers up to 4523 N at 0.9 MPa for pressing bushings or bearings into housings on a semi-automated assembly station, where the extended stroke clears the fixture.
Pallet Lift & Transfer
Acts as the lift cylinder on a pallet dispenser, raising stacks with 2268 N of pulling force. The non-standard stroke is tailored to a specific machine frame height.
Is the Airtac SC80 Standard Cylinder SC80X647 the Right Cylinder?
The SC80X647 suits applications where the 50 mm bore's 982 N force at 0.5 MPa is insufficient, but the full 3927 N of a 100 mm bore is not required. Because the stroke exceeds 300 mm, ensure the rod is not subjected to side loads; long unsupported rods are vulnerable to bending. Use an external linear guide or a guided cylinder if the load is not perfectly axial.
For a direct replacement, match five points: 80 mm bore, 647 mm stroke, PT3/8 port thread, basic mounting (no bracket), and no built-in magnet. This tie-rod cylinder is shorter than an ISO 15552 profile and is not dimensionally interchangeable with that standard.
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 SC80X647 FAQ
At 0.7 MPa supply pressure, the SC80X647 double-acting cylinder produces a theoretical pushing force of 3518 N. The pulling force at the same pressure is slightly lower due to the rod area, rated at 2268 N at 0.5 MPa.
It is not recommended. With a 647 mm stroke and a 25 mm rod, side loads can cause rod deflection and premature bearing wear. For any stroke over 300 mm, an external guide rail or a guided cylinder should be used to absorb transverse forces and protect the rod seals.
