The development of modern medical equipment tends to be high precision, high efficiency and high stability. This not only depends on the development of intelligence, but also has higher requirements for the accessories used in medical equipment – turntable bearings (slewing rings). The stable control ability of medical equipment depends on the precise turntable bearing (slewing bearing). The slewing bearing of medical equipment produced by our company has the characteristics of high precision, low noise, long life and high stability, and has been widely used in X Light machine, mammary gland machine, gamma knife, CT machine and other large medical equipment. The slewing bearing is a very large rolling bearing, which is composed of inner and outer rings and outer rings and rolling elements. The relative rotation of the structure is achieved through the relative rotation of the two-part structural connection and mechanical equipment.

The slewing ring is a new type of mechanical component that is constantly developing with the development of the modern machinery industry. It has gradually developed from applications for excavators, cranes, and other construction machinery to wind power generation equipment, ship machinery, offshore platforms, port machinery, mining and metallurgy, radar antennas, light industrial machinery, and high-end medical equipment in a wide range of industries field. The most common main types of slewing rings are six main structural types: single-row four-point contact ball type, three-row roller type, single-row crossed roller type, double-row different-diameter ball type, ball-column combination type and double-row ball type. In addition, there are steel wire track slewing bearings, which are mainly used in medical CT equipment.
