Introduce the characteristics of bolted ball joints in detail

What is a bolted ball joint? What are its characteristics and standards? Simply put, a bolted ball joint is a joint composed of parts and components such as bolt balls, high-strength bolts, sleeves, fastening screws and cones or sealing plates. Below, China Standard Parts Network introduces the bolt ball joints in detail.

　　 Bolted ball joints have superior performance and can bear loads from all directions. The following introduces the bolt ball joint standard.

　　 This standard applies to the quality control of bolted ball joint parts and components. The bolted ball joint products specified in this standard are suitable for the spatial grid structure of double-layer reticulated shells and flat-plate grids based on the hinged assumption.
