About the Airtac SC80 Standard Cylinder SC80X755S
The AirTAC SC80X755S is a double-acting single-rod 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. With an 80 mm bore and a 755 mm stroke, this model features a 25 mm diameter piston rod and an M20x1.5 rod thread for robust mechanical coupling.
Equipped with a built-in magnet, the SC80X755S allows direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the tie-rod barrel for precise end-of-stroke detection. The adjustable pneumatic cushion at both ends, with a 28 mm cushion length, decelerates the piston smoothly, protecting the end caps during high-speed cycles.

Where the Airtac SC80 Standard Cylinder SC80X755S Is Used
Material Transfer
Pushes heavy totes or bins across a 755 mm span on roller conveyors, with sensor feedback confirming full extension and retraction to the PLC.
Clamping & Fixturing
Applies 2513 N of holding force in a welding or assembly fixture, using the magnet to signal clamp engagement before the cycle starts.
Packaging Compaction
Compresses bulk material into containers with a long 755 mm stroke, stopping precisely at the compacted position via barrel-mounted sensors.
Is the Airtac SC80 Standard Cylinder SC80X755S the Right Cylinder?
Select the SC80X755S for applications needing 2513 N at standard plant air. If your load requires higher force, stepping up to the 100 mm bore provides 3927 N at the same 0.5 MPa pressure. For lighter, faster-moving loads, the 63 mm bore offers 1559 N. Given the 755 mm stroke, ensure the rod is supported against side loads; an external linear guide is recommended to prevent rod bearing wear and bending, as the tie-rod construction is not designed to absorb lateral forces. When replacing an existing cylinder, match five points: 80 mm bore, 755 mm stroke, PT port thread, the built-in magnet sensor option, 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 SC80X755S FAQ
At 0.7 MPa (7 bar) supply pressure, the SC80X755S generates 3518 N of push force. The pull force on the retract stroke is 2268 N due to the area occupied by the 25 mm piston rod.
Yes, the -S suffix designates a built-in magnetic piston. Standard CMSG (reed) or DMSG/EMSG (solid-state) sensors clamp directly onto the cylinder's tie-rod barrel without additional brackets, providing non-contact position sensing.
