About the Airtac SC80 Standard Cylinder SC80X620S
The SC80X620S is a double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa (up to 4523 N at 0.9 MPa), driven by a 25 mm diameter piston rod. With a 620 mm stroke and a body length A of 182 mm, its total extended length reaches approximately 802 mm, making it a capable mid-range actuator for linear transfer and pressing tasks.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the tie-rod barrel for non-contact position sensing. The adjustable air cushion (28 mm length) decelerates the piston near stroke end to reduce impact, while PT3/8 ports and an M20x1.5 rod thread provide standard pneumatic connectivity.

Where the Airtac SC80 Standard Cylinder SC80X620S Is Used
Material Transfer & Indexing
The 620 mm stroke pushes or pulls parts between conveyor lanes or workstations. The built-in magnet enables end-of-stroke confirmation via barrel-mounted sensors for reliable automation sequencing.
Clamping & Light Pressing
With 2513 N at 0.5 MPa, this cylinder applies consistent clamping force for woodworking jigs, welding fixtures, or light assembly presses. The adjustable cushion protects tooling from hammering at cycle end.
Bin Pushing & Diverter Gates
The long 620 mm travel actuates diverter gates or pushes totes off a main line in logistics hubs. Sensor feedback from the -S magnet confirms gate position, preventing collisions.
Is the Airtac SC80 Standard Cylinder SC80X620S the Right Cylinder?
For applications needing more force, stepping up to the SC100 bore provides 3927 N at 0.5 MPa; for a lighter, more compact solution the SC63 delivers 1559 N at the same pressure. At 620 mm stroke, the 25 mm rod is robust, but any significant side load or off-centre mounting can create a bending moment on the rod bearing—consider an external linear guide or a guided cylinder if the load is not purely axial.
When replacing an existing cylinder, match five points: 80 mm bore, 620 mm stroke, PT3/8 port thread, the built-in magnet (-S) for sensor compatibility, and the basic (no bracket) mounting configuration. This SC model is a tie-rod design 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 SC80X620S FAQ
At 0.5 MPa the push force is 2513 N and pull force is 2268 N. At 0.7 MPa push rises to 3518 N, and at the maximum operating pressure of 0.9 MPa it reaches 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf. Always size for your regulated line pressure, not the theoretical maximum.
Yes. The -S suffix means this cylinder has a built-in magnet on the piston. You can clamp CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the tie-rod barrel to detect piston position without any additional brackets or modifications.
