This universal joint primarily consists of a central splined sleeve and three outward-extending bearing blocks. The center sleeve has splined teeth on its inner wall for connection to the drive shaft. The three bearing blocks are evenly spaced 120 degrees apart, each housing a needle or ball bearing and secured by a housing or clamp, creating a unique “tripod” structure. Made entirely of carbon steel with a metallic finish, it offers a compact, durable design.
