    • A bearing is for a tong including a housing and an engagement assembly. The bearing has a monolithic upper bearing element having a substantially planar upper surface and a monolithic lower bearing element having a substantially planar lower surface. The upper and lower bearing elements are configured to mount inside the housing with a substantially same outer horizontal profile as the upper bearing element. The upper bearing element and the lower bearing element define a central open area. The upper bearing element and the lower bearing element have an inner section defining a radial recess opening to the central opening and for receiving the engagement assembly. The upper bearing element and the lower bearing element have outer sections that form a bearing portion radially intermediate the engagement assembly.
    • 轴承用于包括壳体和接合组件的夹钳。 该轴承具有一个具有基本平坦的上表面的整体式上轴承元件和具有基本平坦的下表面的整体下轴承元件。 上和下轴承元件构造成以与上轴承元件基本相同的外水平轮廓安装在壳体内。 上轴承元件和下轴承元件限定中心开口区域。 上轴承元件和下轴承元件具有限定到中心开口的径向凹部并用于接收接合组件的内部部分。 上轴承元件和下轴承元件具有在接合组件的径向中间形成轴承部分的外部部分。
