Slewing bearings (slewing bearings) mostly work under heavy load and low speed conditions. In general, lubricating grease lubrication type can achieve satisfactory results. Commonly used greases are calcium-based grease, lithium-based grease, aluminum-based grease and high temperature grease. Users can choose the appropriate grease according to the specific situation. In many construction equipment, grease spillage is acceptable (with or without sealing devices), but for other applications, such as robots, positioning devices and control devices, grease leakage is not allowed. In many applications, grease leakage can affect product quality and cause safety issues.

　　slewing bearingThe manufacturer believes that the rolling elements are usually separated by spacers. The main functions of the spacer and the cage are to reduce friction, coordinate operating efficiency, distribute load, and guide the circumferential trajectory of the rolling body. As the overall design of the bearing, it is an indispensable part. This structure can maintain the stability of the movement, so it is widely used. Special applications require special ball or roller spacers. For bearings installed on horizontal shafts or continuously rotating generators, as well as bearings used in applications with high positioning and reliability requirements, a strip combination cage can be used to keep the rolling elements in the correct circumferential position.

Slewing bearing manufacturers believe that in many cases, gear teeth can be processed on the inner or outer ring of the bearing to simplify the structure of the transmission system. In order to avoid problems, when determining the structure of the transmission system, try to seek the help of gear experts. Internal gear slewing ring: the overall appearance is neat, the gear andslewing bearingIt is not necessary to install a safety cover at the engagement of. Gear dustproof effect is good, add lubricating oil for a long time. Moreover, the transmission contact stress of the internal gear meshing is low, the wear is small, and the service life is long. External gear slewing bearing: The external gear is easy to process and can make full use of the limited space of the slewing bearing. Fault diagnosis and gear mesh inspection are easy. Due to the larger pitch diameter of the ring gear, a larger transmission ratio can be obtained, and the circumferential force and torque on the pinion can be greatly reduced.

Slewing bearing manufacturers believe that slewing bearings are mainly connected to the base and rotating parts through bolts. Therefore, the number, diameter, length and accuracy of bolts, especially installation, are very important. Not only is the arrangement of the bolts different in different applications, but the inner and outer rings are also different. Bolts and washers shall be installed in accordance with the specified size, number, strength class, etc.
