Our company has rich experience in the production of bearings,specializing in the production of type 0 *9 category bearings, the scope of Ф**0mm*-Ф***00mm different slewing ring structure including the four points contact ball slewing bearing,double row angular contact ball,cross-cylindrical roller slewing bearing,three-row cylindrical roller slewing bearing,and so on.Are widely used in lifting machinery,wind power and high accuracy of radar devices,such as large-scale rotation.
Slewing bearing applications
Slewing bearing are widely used in lifting machinery, mining machinery, construction machinery, port machinery, shipbuilding, machinery, precision machinery radar and missile launchers and other large rotating device.
1. Wind generator
Tower and yaw bearings are installed in the junction of tower and the cockpit; pitch bearings are installed in each blade root and hub joints. Each wind turbine equipment use three sets pitch bearings and a set of yaw bearing. pitch bearing ring material select *2CrMo, treatment with the overall quenching, raceway select surface-hardening. As the wind turbine yaw, pitch bearing’s force is complex and bearings withstand large shock and vibration, therefore, required bearings to withstand both the impact and greater loads. Host wind turbine life requirements of *0 years, bearing the cost of installing large, thus requiring yaw, pitch bearing life have reached *0 years. Bearing rings matrix hardness is 2*0HB*2*0HB, so it is able to withstand shocks but no plastic deformation, meanwhile raceway surface quenching hardness reach to *5HRC**2HRC, also can increase the contact fatigue life, thus ensuring long life bearing requirements.
2. Marine Crane
In general, marine crane use double-row different diameter ball, four-point contact ball, three-row roller inner gear structure slewing bearings. According to the different carrying capacity, three-row roller slewing bearings are usually used for
