Slewing bearings are the most commonly used bearings in the construction machinery and construction machinery industries. According to the structure, it can be divided into: single-row four-point contact ball slewing bearing, double-row four-point contact ball slewing bearing, double-row angular contact thrust ball slewing bearing, crossed cylindrical roller slewing bearing and three-row cylindrical roller slewing bearing, etc. Bearings of different structures can be divided into different types such as toothless type, external gear type and internal gear type according to whether they have teeth or not. Different structures, different sizes and different applications require different materials for slewing bearings.

Under normal circumstances, the slewing bearing ring is selected from 50Mn, but sometimes 42CrMo is selected to meet the needs of the host in special applications. The rolling elements generally use GCr15SiMn. The type of retainer has different structural types such as integral type, segment type, isolation block type, etc. Sealing ring material: oil-resistant rubber, fluorine-containing rubber, oil-resistant nitrile rubber, etc.

No matter what kind of raw material you choose, you must fully consider the actual application and load of the bearing. Luoyang FV specializes in the production of various types of slewing bearings, welcome to contact us.
