What are the structures of the slewing bearing?

     In large-scale or heavy-duty machinery, we can all see the use of slewing bearings. Although they are relatively simple, the corresponding functions and functions are very large. However, this bearing is not a single bearing, they have two large inner and outer ring structures, and the corresponding sealing tape and rolling elements are very important.

     The so-called sealing tape is to allow the bearing to achieve the sealing effect, to ensure that they are combined with the mechanical, sealed main components. If the seal is abnormal or if there is a defect, the sealing effect will be lost at work, and at the same time it will lead to poor quality of the entire project.
     The corresponding rolling elements are the main parts that realize the rolling effect of the slewing bearing and realize the rolling function. If they have a blockage or a stuck condition, the machinery attached to this bearing cannot be rotated and can not be operated, resulting in this machine. Failures and instability of the entire engineering operation. Because of this unfavorable situation, the rolling element is a very important structure for the bearing.

  Tensun use the elements which is made of through-hardening high-carbon chromium. Most common used steel brands are GCr15, GCr15SiMn in Single-row four point contact ball slewing ring bearing, Double-row ball slewing ring bearing, Single-rwo cross roller slewing bearing and Tri-row slewing ring bearing.
