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 42CrMo, 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. 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 heavy-duty cranes, four-point contact ball slewing bearing and double row different diameter ball for light crane. 3. Offshore crane According to different requirement for carrying capacity, offshore crane usually use four-point contact ball slewing bearing and three-row roller inner gear slewing bearing. 4. Port mobile crane Port cranes usually use internal or external gear, 4 meters in diameter three rows roller slewing bearings to withstand high overturning moment. 5. stacker-reclaimer Slewing bearing stacker-reclaimer usually use is ball column combined type, three-row roller and cross-roller, the majority diameter over 3 meters. Due to poor working conditions, dusty, these bearings have high load capacity, long life and good sealing performance feature. 6. Ferris wheel Usually use four-point contact ball slewing bearing, diameter 4100mm, thickness 85mm. 7. Ship unloaders Usually use three rows of outer roller tooth structure, about 4 meters in diameter 8. Tower crane Usually use small size four-point contact ball bearings or double-row ball, diameter not more than 2 meters 9. Radar antenna Usually use three-row roller slewing bearing, slow rotation 10. Shield Diameter from 2.5 meters to 6 meters, some larger diameter, these bearings work in very poor conditions, bearing a large load, corrosion resistance, short life. 11. Ladle turret in steel plant Usually these bearing are three-row roller slewing bearings, because work in the dust and high temperature conditions, so s have high demands for maintain, grease and seal. 12. Engineering machinery Usually use small size four-point contact ball bearings or double-row ball, diameter not more than 2 meters
