About the Airtac SC80 Standard Cylinder SC80X625S
The SC80X625S is an 80 mm bore, 625 mm stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod series. It generates a push force of 2513 N at 0.5 MPa and up to 4523 N at the maximum operating pressure of 0.9 MPa, making it a robust choice for medium-to-heavy linear actuation tasks.
This model features a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for reliable end-of-stroke detection. The 25 mm diameter piston rod and 28 mm adjustable air cushion at each end provide smooth deceleration, while the PT1/8 port thread ensures straightforward pneumatic connections.

Where the Airtac SC80 Standard Cylinder SC80X625S Is Used
Material Transfer
Pushes heavy totes or pallets off a main conveyor line onto a branch, using the 625 mm stroke to fully clear the transfer zone.
Press-Fit Assembly
Delivers over 4500 N of force at 0.9 MPa to press bearings or bushings into housings, with sensor confirmation of complete stroke.
Sawmill Log Flipper
Actuates a flipping arm to rotate and position logs on a deck, leveraging the long stroke and high force capacity in a dusty environment.
Is the Airtac SC80 Standard Cylinder SC80X625S the Right Cylinder?
For applications requiring slightly less force, the 63 mm bore SC series provides 1559 N at 0.5 MPa, while stepping up to the 100 mm bore delivers 3927 N. At a 625 mm stroke, the 25 mm rod is well-supported within the 80 mm bore, but any significant side loading should be managed with an external linear guide to prevent rod bearing wear and ensure long service life.
To replace an existing cylinder, match five key points: the 80 mm bore, 625 mm stroke, PT port thread, the built-in magnet for sensor compatibility, and the basic mounting configuration. This 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 SC80X625S FAQ
At the standard 0.5 MPa operating pressure, 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.
Yes. The -S suffix in SC80X625S designates a built-in magnet in the piston. This allows AirTAC CMSG, DMSG, or EMSG sensors to be clamped directly onto the barrel's external tie-rod grooves for non-contact position sensing.
