Carter Hitachi Komatsu excavator slewing ring

Lunda Luoyang Bearing Co., Ltd. to provide you with a wealth of information and information on? CATERPILLAR pictures and so on. Four-point contact ball bearing is a separate type of bearings, it can be said to be an angular contact ball bearings can withstand two-way axial load bearing inner and outer ring raceway is peach shaped cross-section, when there is no load or pure radial load When the role of the ball and rings appear as a four-point contact, which is also the origin of the name; when only pure axial load, balls and rings became a two-point contact, can bear axial loads. Four point contact ball bearings can withstand torque loads, both the single row angular contact ball bearings and double row angular contact ball bearings feature. In order to ensure the normal operation of four-point contact ball bearing only the formation of two-point contact. It is generally suitable for those under pure axial load or axial load large combined load of the occasion was a two-point contact, four-point contact ball bearing high speed limit, but also for those high-speed operation of the occasion.
