About the Airtac SC80 Standard Cylinder SC80X655S
The AirTAC SC80X655S is an 80 mm bore double-acting tie-rod cylinder with a 655 mm stroke and a built-in magnet for barrel-mounted sensors. It produces 2513 N of push force at 0.5 MPa and up to 4523 N at the maximum operating pressure of 0.9 MPa, making it a capable mid-range actuator for general automation.
This model features a 25 mm diameter piston rod with M20x1.5 threads, PT3/8 pneumatic ports, and a 28 mm adjustable air cushion at each end. The integrated magnet allows direct clamping of CMSG, DMSG, or EMSG reed and solid-state sensors to the barrel for non-contact position sensing. The body length A is 182 mm, giving a total extended length of approximately 837 mm.

Where the Airtac SC80 Standard Cylinder SC80X655S Is Used
Material Handling Gates
The 655 mm stroke and 2513 N push force at 0.5 MPa operate diverter gates and stops on wide conveyor lines, with the built-in magnet providing reliable end-of-stroke confirmation.
Automated Press Feeding
Delivers consistent part transfer into stamping or forming presses. The adjustable cushion decelerates the 25 mm rod smoothly at the end of the 655 mm travel, protecting tooling.
Pallet Layer Positioning
Positions a pallet dispenser carriage across a 655 mm range. The magnet-equipped barrel simplifies sensor mounting for mid-stroke deceleration and final position verification.
Is the Airtac SC80 Standard Cylinder SC80X655S the Right Cylinder?
For applications requiring slightly less force, the 63 mm bore SC63 series provides 1559 N at 0.5 MPa. If higher force is needed, stepping up to the 100 mm bore delivers 3927 N at the same pressure. The 655 mm stroke is within the 1500 mm maximum standard stroke for the 80 mm bore.
At this stroke length, consider external guides or a guided cylinder if the rod will experience significant side loads, as the unsupported 25 mm rod can bend under lateral force. When replacing an existing cylinder, match five key points: 80 mm bore, 655 mm stroke, PT3/8 port thread, the built-in magnet (-S suffix), and the basic mounting configuration.
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 SC80X655S FAQ
At the standard operating pressure of 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, the push force increases to 4523 N. The theoretical maximum force at 1.0 MPa is 513 kgf.
Yes. The -S suffix indicates a built-in magnet on the piston, allowing you to clamp CMSG, DMSG, or EMSG reed and solid-state sensors directly onto the tie-rod barrel for non-contact position detection without additional mounting brackets.
