Vehicular e.g. brake needle bearing shell made from punched flat metal

摘要

A needle bearing has an outer shell (11) and a needle cage (21). The cage is punched from a piece of flat sheet metal and then rolled into a cylinder. The shell incorporates a window (15) and the needle cage has a matching window (27). The needle cage fits axially and circumferentially within the shell so that the windows face each other, providing access through both windows for a pressure pin (45).
