About the Airtac SAI80 Standard Air Cylinder SAI80X500SLB
The AirTAC SAI80X500-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust 2513 N of push force at 0.5 MPa, this 80 mm bore unit utilizes a 500 mm stroke to drive substantial loads across long distances. The extruded aluminum barrel design omits tie-rods, providing a clean exterior that drops directly into standard ISO 15552 mounting interfaces.
Equipped with a magnet for position sensing, this variant operates seamlessly with CMSE and DMSE switches fitted into the dual sensor grooves machined into the barrel. The standard carbon steel piston rod ensures high tensile strength for demanding cycles, while the PT tapered port threads guarantee a secure, leak-free pneumatic connection. Adjustable air cushions at both ends absorb kinetic energy to protect the end caps.

Where the Airtac SAI80 Standard Air Cylinder SAI80X500SLB Is Used
Material Transfer
Pushes heavy pallets or product totes over a 500 mm gap on automated packaging lines, utilizing the 2513 N thrust to overcome friction.
Press Ejection
Extends fully to clear stamped metal parts from a press bed, relying on the adjustable air cushions to decelerate the payload smoothly.
Diverting Arms
Actuates large sorting diverters in high-throughput distribution centers, with the integrated magnet triggering DMSE sensors for precise positioning.
Is the Airtac SAI80 Standard Air Cylinder SAI80X500SLB the Right Cylinder?
Selecting this 80 mm bore is ideal when an application demands more power than a 63 mm cylinder, which offers 1559 N at 0.5 MPa, but does not yet require the 3927 N thrust of a 100 mm unit. The 500 mm stroke provides extensive reach, though an unsupported rod of this length is susceptible to bending under side loads. To prevent premature rod-bearing wear, incorporate an external guide rail or utilize a dedicated guided cylinder to absorb lateral forces.
This configuration features an LB foot mounting accessory and a magnet for sensors. Because it is a standard double-acting cylinder, it will not maintain its position if air pressure is lost; applications requiring static holding must utilize the SAIL locking variant or an external pilot-operated check valve. As a dimensionally interchangeable ISO 15552 component, it serves as a straightforward drop-in replacement for other cylinders matching this bore, stroke, and G3/8 port size.
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 SAI80X500SLB FAQ
At a standard operating pressure of 0.5 MPa, this 80 mm bore cylinder generates 2513 N of push force and 2268 N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 3518 N.
Yes, the SAI80X500-S is built to the ISO 15552 profile standard, making its mounting dimensions and G3/8 port fully interchangeable with other ISO 15552 cylinders of the same bore and stroke. It is not a tie-rod design, ensuring a clean exterior profile.
