About the Airtac SC80 Standard Cylinder SC80X520S
The SC80X520S is a double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa and up to 4523 N at 0.9 MPa, making it a robust choice for medium-to-heavy automation tasks. Its 25 mm diameter piston rod and 28 mm adjustable air cushion provide smooth deceleration for the 520 mm stroke, while the built-in magnet allows direct mounting of CMSG/DMSG/EMSG sensors for reliable end-of-stroke detection.
This genuine AirTAC SC series cylinder uses a tie-rod construction that is shorter than an equivalent ISO 15552 profile, saving space in machine layouts. With a body length of 182 mm, the total extended length is approximately 702 mm, and the PT3/8 port supplies ample flow for speeds up to 800 mm/s.

Where the Airtac SC80 Standard Cylinder SC80X520S Is Used
Material Transfer
Pushes or diverts medium-weight packages and totes on conveyor lines, with sensor feedback confirming each cycle.
Press & Clamp Fixtures
Generates over 4500 N of clamping force at 0.9 MPa for holding parts during welding, gluing, or assembly operations.
Palletising Systems
Actuates layer-forming pushers in palletisers, where the 520 mm stroke spans multiple product rows.
Is the Airtac SC80 Standard Cylinder SC80X520S the Right Cylinder?
For applications needing more force, stepping up to the SC100 bore provides 3927 N at 0.5 MPa, while the SC63 bore offers 1559 N if a smaller footprint is required. When replacing an existing cylinder, match five key points: 80 mm bore, 520 mm stroke, PT3/8 port thread, the built-in magnet (-S suffix), and the basic mounting style.
At a 520 mm stroke, ensure the load is guided externally to prevent side-load bending on the 25 mm rod. For unguided loads, consider pairing this cylinder with an external linear guide or switching to a guided cylinder assembly.
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 SC80X520S 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, push force reaches 4523 N. The theoretical maximum at1.0 MPa is 513 kgf.
Yes. The -S suffix indicates a built-in magnet, so AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors can be clamped directly onto the barrel to detect piston position.
