About the Airtac SC80 Standard Cylinder SC80X690
The AirTAC SC80X690 is a double-acting pneumatic 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. Its 25 mm diameter piston rod and 28 mm adjustable air cushion are engineered for reliable mid-range industrial automation tasks.
With a 690 mm stroke, this model provides an extended reach within the standard stroke limit for the 80 mm bore. The compact tie-rod body has a length A of 182 mm, making it shorter than an equivalent ISO 15552 cylinder. PT3/8 ports and an M20x1.5 rod thread ensure straightforward pneumatic connections.

Where the Airtac SC80 Standard Cylinder SC80X690 Is Used
Material Transfer
Pushes heavy totes or pallets across a 690 mm transfer station, leveraging the 2513 N force at standard line pressure.
Press-Fit Assembly
Provides the controlled 4523 N thrust at 0.9 MPa for inserting bearings or bushings into housings on an assembly line.
Bin Diverter
Actuates a diverter gate on a gravity conveyor, using the long 690 mm stroke to fully redirect product flow between lanes.
Is the Airtac SC80 Standard Cylinder SC80X690 the Right Cylinder?
Select the SC80 bore when your application requires between 2513 N and 4523 N of force. For lower force needs, stepping down to a 63 mm bore provides 1559 N at 0.5 MPa, while moving up to a 100 mm bore offers 3927 N. This 690 mm stroke generates significant bending moment on the rod; use an external guide or rod support to prevent bearing wear from side loads.
For a direct replacement, match the 80 mm bore, 690 mm stroke, PT3/8 port thread, and basic mounting configuration. If your original cylinder had a magnet, order SC80X690-S to accept CMSG/DMSG sensors.
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 SC80X690 FAQ
At 0.5 MPa, the push force is 2513 N. At the maximum operating pressure of 0.9 MPa, it reaches 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf.
For strokes over 300 mm, side loads can cause rod deflection and seal wear. Install an external linear guide rail parallel to the cylinder to absorb transverse forces, or switch to a guided cylinder unit.
