About the Airtac SAI80 Standard Air Cylinder SAI80X900S
The AirTAC SAI80X900-S is a double-acting ISO 15552 profile cylinder featuring an 80mm bore and a 900mm stroke. It delivers a robust 2513N push force at 0.5 MPa, making it well-suited for heavy-duty linear actuation over extended distances. The extruded aluminum barrel lacks tie-rods, presenting a clean exterior that drops directly into standardized ISO 15552 mounting interfaces.
Equipped with a magnetic piston (-S), this unit supports CMSE and DMSE sensor switches via dual grooves on the barrel. The standard carbon steel piston rod provides durable service, while adjustable air cushions at both ends manage impact deceleration. For environments exceeding standard thermal limits, Viton (H) seals are available to maintain integrity.

Where the Airtac SAI80 Standard Air Cylinder SAI80X900S Is Used
Extended Material Transfer
Drives long-travel conveyor diverters and heavy pallet pushers over the full 900mm stroke distance.
Automated Assembly Line
Positions large subassemblies or machinery components with 2513N of thrust at 0.5 MPa operating pressure.
High-Bay Storage Retrieval
Actuates vertical lifting arms in automated storage systems where extended reach and magnetic positioning feedback are required.
Is the Airtac SAI80 Standard Air Cylinder SAI80X900S the Right Cylinder?
Stepping up to a 100mm bore increases the 0.5 MPa push force to 3927N for heavier payloads, while dropping to a 63mm bore reduces it to 1559N for lighter, faster tasks. At 900mm of travel, the unsupported piston rod is highly susceptible to bending under side loads. To prevent premature rod-bearing wear, implement an external guide rail or select a guided cylinder to absorb lateral forces.
This model uses a G3/8 port with PT tapered threading and operates at 30-800 mm/s. Mounting accessories include FA/FB flanges or TC trunnions. Note that the adjustable cushions only decelerate the piston near stroke ends; they do not hold the load. If the application requires position holding upon air loss, specify the SAIL (air-released lock) or BSAI (clamp-lock) variant.
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.
