PROBLEM TO BE SOLVED: To prevent the leakage of lubricant and improve low noise characteristics or a high speed rotating performance in a bearing having an inclining mechanism of an axis such as a spherical bearing, a rod end bearing, a roller bearing, a ball bearing or the like. SOLUTION: The rod end bearing 13 has the inclining mechanism A and a rotating mechanism B independent of each other. The inclining mechanism A has a non-lubricant type spherical sliding bearing structure (16, 17, 17a). The rotating mechanism B has a rolling bearing structure with a seal (18, 19, 20, 21, 23). The axis can be inclined by the non-lubricant type spherical sliding bearing structure. A high speed rotation or a continuous rotation can be carried out without generating a problem of the leakage of the lubricant by the rolling bearing structure with the seal. The rolling bearing structure with the seal of the rotating mechanism B is not requested for the inclining function of the axis. Thus, a material of the seal 23 used therefor is determined in view of a sliding resistance and a high durability. COPYRIGHT: (C)2003,JPO |
