Light weight; compact structure; can accept axial force, radial force and tipping moment at the same time.The size of the single-row ball slewing bearing is large, and its diameter is generally 0.4 to 10 meters, and some are as high as 40 meters. Slewing bearings generally have to accept loads from several aspects, not only axial force and radial force,...

1. Whether the running condition of the slewing bearing is good depends on the size and surface finish of the matching part of the slewing bearing.2. Improper addition of grease. During the operation of the slewing bearing, lubrication is very important, and the correct use can ensure its normal life. Adding dirty or excessive grease can cause the slewi...

Bearing runout can be divided into synchronous runout and asynchronous runout. The influence of synchronous runout on the overall runout of the worktable can be minimized by grinding the worktable, but the influence of asynchronous runout cannot be eliminated in this link. It is determined by the outer diameter tolerance and roundness of the rollers. Th...

The installation surface of the shaft and the ring gear is required to have the same flatness, perpendicularity, roundness and cylindricity as the fine bearing. Controlling these form and position common services can not only achieve better installation accuracy, but also prevent excessive eccentricity of the inner and outer rings of the bearing from ca...

In the cutting test of the vertical lathe, great attention is paid to the end face and outer circle roughness of the workpiece, and one of the keys to determine its quality is the rigidity of the system. The system rigidity includes the rigidity of the frame structure, the rigidity of the support bearing, etc., during which the rigidity of the bearing o...
