About the Airtac SC80 Standard Cylinder SC80X475S
The AirTAC SC80X475S is a double-acting tie-rod cylinder with an 80 mm bore and a 475 mm stroke, delivering a push force of 2513 N at 0.5 MPa (4523 N at 0.9 MPa). The piston rod is 25 mm in diameter with an M20x1.5 male thread, and the adjustable air cushion provides a 28 mm deceleration zone at each end to soften end-of-stroke impact.
The built-in magnet (denoted by the -S suffix) allows CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the barrel for non-contact position sensing. With PT1/4 ports and standard TPU seals, this cylinder operates reliably from -20 to +70 °C, making it a versatile workhorse for medium-duty automation tasks.

Where the Airtac SC80 Standard Cylinder SC80X475S Is Used
Material Transfer
Pushes or lifts bins and totes on roller conveyors with 2513 N of force at standard shop air, while the magnetic piston lets sensors confirm end-of-travel.
Clamping & Fixturing
Applies consistent 4523 N clamping force at 0.9 MPa for CNC weld fixtures and assembly jigs, with sensor feedback to interlock machine safety.
Palletising Pushers
Moves boxes or layers onto a pallet with a 475 mm stroke. The adjustable cushion protects the cylinder and load from hard stops at high cycle rates.
Is the Airtac SC80 Standard Cylinder SC80X475S the Right Cylinder?
This 80 mm bore cylinder is a strong mid-range actuator. If your application requires less force, stepping down to a 63 mm bore provides 1559 N push at 0.5 MPa; for higher thrust, the 100 mm bore offers 3927 N at the same pressure. Always match the replacement cylinder on five points: bore (80 mm), stroke (475 mm), port thread (PT), mounting accessory (basic), and the magnet option (-S) to retain sensor compatibility.
With a 475 mm stroke, the 25 mm rod is extended significantly. In applications with any side load, even a small off-axis force can create a bending moment on the rod bearing. Use an external linear guide or a guided cylinder assembly to protect the rod and seals from premature wear.
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 SC80X475S FAQ
At 0.5 MPa the cylinder pushes with 2513 N and pulls with 2268 N. At the maximum operating pressure of 0.9 MPa, the push force rises to 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf.
Yes, the SC80X475S is a direct dimensional replacement for a non-magnet SC80X475, but it adds a built-in magnet. If your existing setup does not use sensors, the magnet has no negative effect. Ensure the port thread (PT), mounting, and stroke match.
