About the Airtac SAI80 Standard Air Cylinder SAI80X475S
The AirTAC SAI80X475-S is a double-acting ISO 15552 profile cylinder engineered to deliver 2513 N of push force and 2268 N of pull force at 0.5 MPa. This 80 mm bore unit with a 475 mm stroke is built for rigorous automated handling. The integrated magnet (-S) enables seamless position feedback when paired with CMSE or DMSE switches mounted directly into the extruded aluminum barrel grooves.
Constructed with a robust carbon steel piston rod and standard TPU seals, this model handles operating pressures from 0.15-1.0 MPa. The adjustable air cushions at both ends absorb kinetic energy, ensuring smooth deceleration at speeds up to 800 mm/s.

Where the Airtac SAI80 Standard Air Cylinder SAI80X475S Is Used
Automated Press Clamping
Provides reliable 2513 N clamping force at 0.5 MPa for securing heavy sheet metal components during robotic welding or machining operations.
Pallet Diverting
Extends 475 mm to push heavy product pallets from a main conveyor line onto secondary packaging tracks with smooth, cushioned deceleration.
Vertical Lift Gates
Actuates large material handling safety gates, using the magnetic piston to confirm fully open and closed positions for interlock systems.
Is the Airtac SAI80 Standard Air Cylinder SAI80X475S the Right Cylinder?
Select this 80 mm bore when a 63 mm cylinder lacks thrust, specifically needing more than the 1559 N push force of the smaller bore at 0.5 MPa. Conversely, if your application requires less than 2200 N, stepping down to the 63 mm variant saves space and air consumption. The PT tapered port thread guarantees a tight, leak-free pneumatic connection.
Because the 475 mm stroke creates an extended rod length, avoid mounting loads directly to the rod end to prevent rod-bearing bending and premature seal wear under side load. Implement an external guide rail or select a twin-rod guided cylinder for heavy off-center loads. Note that standard SAI cylinders drift when air pressure is removed; utilize the BSAI clamp-lock variant if the mechanism must hold position during an emergency stop or pressure loss.
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 SAI80 Standard Air Cylinder SAI80X475S FAQ
At 0.5 MPa, this 80 mm bore cylinder generates 2513 N of push force and 2268 N of pull force. If operating at 0.7 MPa, the push force increases to 3518 N.
Yes, the SAI80X475-S is dimensionally interchangeable per ISO 15552. It serves as a drop-in replacement for other ISO 15552 profile cylinders with matching 80 mm bore and 475 mm stroke specifications.
