About the Airtac SC80 Standard Cylinder SC80X737S
The SC80X737S is an 80 mm bore double-acting pneumatic cylinder with a 737 mm stroke, pre-fitted with a magnet for direct mounting of CMSG/DMSG/EMSG sensors. At 0.5 MPa it generates 2513 N push and 2268 N pull, rising to 4523 N push at the 0.9 MPa maximum operating pressure.
This model uses a 25 mm diameter piston rod with M20x1.5 male threads and PT3/8 ports. The adjustable air cushion is 28 mm long, and the tie-rod body length A is 182 mm, giving an extended length of approximately 919 mm. The standard TPU/NBR seals suit ambient temperatures from -20 to +70 °C.

Where the Airtac SC80 Standard Cylinder SC80X737S Is Used
Long-Stroke Part Transfer
The 737 mm stroke moves components between distant conveyor stations. The built-in magnet allows end-of-stroke sensing without external brackets, simplifying automation integration.
Pallet Layer Forming
Pushes a row of boxes onto a pallet layer with 2513 N of force at standard line pressure. The adjustable cushion decelerates the heavy load quietly at the end of the 737 mm travel.
Automated Saw or Cut-Off Pusher
Feeds long extrusions or lumber into a cut-off saw. The 25 mm rod and tie-rod construction provide rigidity across the long stroke, while the magnetic piston enables precise position confirmation.
Is the Airtac SC80 Standard Cylinder SC80X737S the Right Cylinder?
Choose the SC80 when the SC63's 1559 N push at 0.5 MPa is marginal for your load; step up to the SC100 (3927 N at 0.5 MPa) if the 80 mm bore is borderline. For this 737 mm stroke, ensure the rod is not subjected to lateral forces at full extension—long, unsupported rods can bend under side load. Add an external linear guide or switch to a guided cylinder if the load is not purely axial.
For direct replacement, match five points: 80 mm bore, 737 mm stroke, PT3/8 port thread, the built-in magnet (-S suffix), and the basic mounting style. The SC is a tie-rod cylinder 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 SC80X737S FAQ
At 0.5 MPa the push force is 2513 N and the pull force is 2268 N. At 0.7 MPa push force is 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.
Yes. The -S suffix indicates a built-in magnet in the piston, so AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors clip directly onto the barrel tie-rods. No external actuator dogs or brackets are needed.
