Patent ID: 6941656

Claim:
A method for manufacturing a spherical bearing having an inner member with a ball section and an outer member with a ball bearing section for enclosing and holding the ball section of the inner member to be coupled with the inner member such that it can be swung or rotated relative to the inner member, which comprises the steps of: attaching a resin liner to the ball section of the inner member using injection molding with the ball section inserted as a core, for forming a resin sliding contact surface in tight contact with the ball section, wherein the resin line will be entirely encompassed by the ball bearing section; performing die casting of the ball bearing section that covers the resin liner with the ball section having the resin liner inserted in the casting dies, for forming a metal sliding surface in tight contact with the ball section of the inner member, wherein the resin sliding contact surface is contiguous to the metal sliding contact surface without any gap, to form a single sliding contact surface of the ball bearing section and applying an external force to the ball section or ball bearing section, thereby allowing the ball section and ball bearing section to rotate relative to each other.
