Slewing ring bearing member of the materials used
  Under normal circumstances, the slewing ring rolling using whole-hardened carbon chromium bearing steel. Grades or GCr15SiMn GCr15 steel; slewing ring rings surface hardened steel is used, when the user no special requirements, generally used 50Mn steel, but sometimes in order to meet the needs of some of the special applications of the host, but also according to user-provided specific conditions of use choose other brands of surface hardened steel, such as 42CrMo, 5CrMnMo like.

Cage materials
    Slewing bearing retainer has a structure with a monolithic, segmented, isolated block type and the like. Wherein the monolithic and segmented cage with 20 steel or ZL102 cast aluminum alloy. Isolation Block 1010 polyamide resin, ZL102 cast aluminum alloy or the like. In recent years, with the development of nylon GRPA66.25 materials industry is also segmented cage design to application.

Seal material
    Slewing ring seal material NBR manufactured using oil.
