A Ball joint consists of a spherical bearing housed within a socket, allowing for rotational movement in multiple directions. The ball joint allows for rotational movement and articulation of the screed assembly. It enables the screed to adjust and align with the contours of the ground or pavement surface during the paving or leveling process.Attributes:• Constructed from durable materials to provide strength, stability, and resistance to wear and fatigue.• Have flexibility, which helps in achieving a smooth and even finished pavement surface.Application:A ball joint in a frame is a component that is often used to provide articulation and flexibility in the movement of the screed assembly.
