A half yoke assembly is a mechanical component that consists of only one of the two arms of a yoke. The yoke arm is typically shaped like a fork or a U, with a single arm that is parallel to the ground and spaced apart by a distance that matches the width of the gear or component it is intended to connect to.

Half yoke assemblies are commonly used in automotive and industrial applications where space constraints or other factors make it difficult or impractical to use a full yoke assembly. For example, a half yoke may be used to connect a driveshaft to a differential or a transfer case in a vehicle, or to connect a motor to a gearbox in an industrial machine.

Like full yoke assemblies, half yoke assemblies may include other components such as bearings, seals, and fasteners to ensure proper function and durability. Half yoke assemblies are typically designed to be compatible with specific gear ratios, shaft sizes, and other specifications, and may require careful matching and installation to ensure proper alignment and function.
