About the Airtac SAI80 Standard Air Cylinder SAI80BX1000
The AirTAC SAI80X1000 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty linear motion. It provides a robust push force of 2513 N at 0.5 MPa and 3518 N at 0.7 MPa, making it well-suited for moving substantial loads over its 1000 mm stroke. The extruded aluminum barrel design omits tie rods, offering a clean exterior that integrates seamlessly into modern machinery.
This specific configuration features a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in humid or washdown environments. It utilizes PT tapered port threads and lacks a standard magnet, meaning position sensing via CMSE or DMSE switches is not enabled out of the box.

Where the Airtac SAI80 Standard Air Cylinder SAI80BX1000 Is Used
Long-Stroke Material Transfer
Pushes heavy pallets or workpieces across a 1000 mm span, utilizing the 2513 N push force at 0.5 MPa to overcome friction on roller conveyors.
Large Door Actuation
Opens and closes heavy industrial machine guarding doors or blast cabinet hatches, where the SUS304 rod provides resistance against harsh environmental exposure.
Heavy Press Indexing
Indexes large automotive or structural components into a hydraulic press, relying on the adjustable air cushions at both ends to decelerate the 80 mm piston smoothly.
Is the Airtac SAI80 Standard Air Cylinder SAI80BX1000 the Right Cylinder?
Selecting this 80 mm bore cylinder makes sense when your application requires substantial thrust that a 63 mm bore (1402 N pull at 0.5 MPa) cannot provide, but a 100 mm bore would be physically oversized. At a 1000 mm stroke, the unsupported piston rod is highly susceptible to bending under side loads. You must use an external linear guide or a guided cylinder carriage to prevent premature rod-bearing wear and seal failure.
Because this is a standard double-acting cylinder, it will not hold a load in place if air pressure drops or the valve is centered. For suspended or vertical loads that require failsafe holding without live pressure, specify the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock. As a dimensionally interchangeable ISO 15552 unit, it serves as a direct replacement for other standard profile cylinders matching the 80 mm bore, 1000 mm stroke, G3/8 port, and standard mounting accessories like FA flange or TC trunnion.
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 SAI80BX1000 FAQ
The SAI80X1000 generates a push force of 2513 N at 0.5 MPa, 3518 N at 0.7 MPa, and 4523 N at 0.9 MPa. The pull force at 0.5 MPa is 2268 N.
No, a 1000 mm stroke creates a long lever arm that can bend the rod and damage the bearing under side load. You must use an external linear guide or a guided cylinder to support the load independently of the piston rod.
