Zurn F-203SB Amerigear Flexible Coupling Sleeve

The Zurn F-203SB Amerigear Flexible Coupling Sleeve is a machined medium carbon steel gear coupling sleeve that connects and transmits torque between rotating shafts in mechanical power transmission systems. Designed to accommodate angular misalignment of approximately ±1.5° per gear mesh, it uses the Amerigear Series F flexible gear coupling design and mounts as a flanged sleeve with shrouded bolts (SB configuration) for installation in heavy-duty drives. Commonly installed in industrial drive systems, pumps, conveyors, and other heavy machinery, it supports reliable power transfer in manufacturing plants, mining operations, power generation facilities, and material handling environments where rotating equipment requires a flexible coupling solution to tolerate misalignment. This component is part of Amerigear Series F gear coupling assemblies for repair, retrofit, or replacement of worn or damaged parts, and may be discontinued or have limited availability.
