About the Airtac SC80 Standard Cylinder SC80X635SN
The AirTAC SC80X635SN is a double-acting single-rod pneumatic cylinder delivering 2513 N push force at 0.5 MPa (4523 N at the 0.9 MPa maximum operating pressure). Its 635 mm stroke suits medium-reach material-transfer and clamping applications, while the 25 mm diameter piston rod and 28 mm adjustable air cushion provide reliable end-of-stroke deceleration.
This model is factory-equipped with a built-in magnet (-S suffix), allowing CMSG/DMSG/EMSG reed or solid-state sensors to be clamped directly onto the tie-rod barrel for non-contact position sensing. The N suffix specifies NBR (nitrile) seals, and the standard PT1/4 port thread is retained. The body length A is 182 mm, giving a total extended length of approximately 817 mm.

Where the Airtac SC80 Standard Cylinder SC80X635SN Is Used
Material Transfer
The 635 mm stroke and 2513 N push force at 0.5 MPa reliably shift parts between conveyor lanes or into packaging stations, with the magnetic piston enabling end-of-stroke sensor confirmation.
Pneumatic Clamping
Applies consistent holding force in woodworking or assembly jigs. The NBR seals offer good resilience for general-purpose factory air, and the adjustable cushion protects the fixture from impact.
Automated Sorting Gates
Actuates diverter gates on production lines. The built-in magnet supports CMSG/DMSG sensors for precise gate-open and gate-closed feedback to the PLC, ensuring accurate product routing.
Is the Airtac SC80 Standard Cylinder SC80X635SN the Right Cylinder?
For higher force, the 100 mm bore SC100 series provides 3927 N at 0.5 MPa; for a smaller footprint, the 63 mm bore delivers 1559 N. At 635 mm stroke, the rod is well-supported for axial loads, but any significant side loading requires an external linear guide or a guided cylinder to prevent rod-bearing bending and premature seal wear.
To replace an existing cylinder, match five points: 80 mm bore, 635 mm stroke, PT1/4 port thread, the NBR seal material, and the built-in magnet for sensor compatibility. The SC series is a tie-rod design 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 SC80X635SN FAQ
At 0.5 MPa the theoretical push force is 2513 N, and at 0.7 MPa it is 3518 N. The maximum operating force at 0.9 MPa is 4523 N. Pull force on the return stroke is slightly lower due to the 25 mm rod area: 2268 N at 0.5 MPa.
Yes. The -S suffix indicates a built-in magnet is fitted inside the piston. This allows AirTAC CMSG, DMSG, or EMSG series sensors to be mounted directly on the cylinder barrel for contactless position detection.
