Accurate depiction and correct and reasonable selection of bearing making materials are important guarantees for high technical performance and high reliability of slewing bearings.
For ferrules and tumbling materials, normally, the tumbling bearing tumbling body is made of all hardened carbon-chromium bearing steel; the trademark is made of Cr15SiMn or GCr15 steel, and the bearing sleeve is made of external hardened steel; when the user has no special requirements; Usually made of 50Mn steel, but sometimes in order to satisfy the needs of some special occasions host; also can choose other trademarks of hardened steel grade according to the specific conditions of the user supply; such as 42CrMo, 5CrMnMo and so on.
The retainer type used for the retainer data slewing bearing has a different layout type such as a full cage, a segmented cage or a block cage. In the meantime, the whole cage or the segmented cage is made of steel No. 20 Or ZL102 cast aluminum alloy. Block type cage is made of polyamide 1010 resin, ZL102 cast aluminum alloy or QA11O-3-1. 5 aluminum bronze. These years follow the development of the data industry nylon GRPA66.25 is also in The segment cage is used in the depiction.
The sealing material for the sealing ring is used for the material of the bearing slewing ring and the oil is used for the production of NBR rubber. However, there are a few early LDB slewing bearings that have been used for wool felt seals.
