Abstract
A ball joint () for a chassis of a vehicle has an inner joint portion () and a one-piece slide bearing () made of plastic. A joint ball () of the inner joint portion () is fitted so that it can swivel in a ball-bearing section (). The slide bearing () has a holding section () for the arrangement of a sensor element (). In order to simplify the structure and/or assembly of the ball joint (), the outside of the slide bearing () has a circular-ring-shaped contact surface () which is formed coaxially relative to a central longitudinal axis () of the slide bearing () and which co-operates with a separate closure ring () surrounding the outside of the slide bearing () to fix the slide bearing () in a joint housing ().
