About the Airtac SC80 Standard Cylinder SC80X285S
The SC80X285S is a double-acting pneumatic cylinder with an 80 mm bore and 285 mm stroke, delivering a push force of 2513 N at 0.5 MPa and up to 4523 N at the maximum operating pressure of 0.9 MPa. Its 25 mm diameter piston rod and 28 mm adjustable air cushion provide reliable deceleration for mid-stroke applications.
This model includes a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for contactless position sensing. The standard PT1/8 port and TPU seals suit filtered-air systems operating between -20 and +70 °C.

Where the Airtac SC80 Standard Cylinder SC80X285S Is Used
Material Handling Pusher
The 285 mm stroke and 2513 N push force at 0.5 MPa efficiently transfer boxes or totes between conveyor lanes, with the built-in magnet providing end-of-stroke confirmation.
Clamping & Fixturing
Delivers up to 4523 N at 0.9 MPa for secure workpiece clamping in CNC machining centres, where the -S magnet enables sensor-based cycle interlocking.
Pallet Stop & Lift Gate
Controls pallet flow in gravity or powered roller systems; the adjustable cushion absorbs impact energy smoothly over the 28 mm cushion length, protecting the cylinder and structure.
Is the Airtac SC80 Standard Cylinder SC80X285S the Right Cylinder?
Choose the SC80 bore when your application needs between 2513 N and 4523 N of force; for lighter loads, the SC63 bore provides 1559 N at 0.5 MPa, while the SC100 bore steps up to 3927 N. For this 285 mm stroke, ensure the rod is not subjected to side loading—if lateral forces are present, pair the cylinder with an external linear guide or consider a guided cylinder to prevent rod bending and premature bearing wear.
When replacing an existing cylinder, match five key points: 80 mm bore, 285 mm stroke, PT1/8 port thread, the built-in magnet for sensor compatibility, and the basic (no bracket) 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 SC80X285S FAQ
At 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 reaches 4523 N. The theoretical maximum force at 1.0 MPa is 513 kgf.
Yes. The -S suffix indicates a built-in magnet, so you can clamp CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel to detect piston position without additional brackets.
