【 Jiaxing read bearing 】 Slewing bearing component part and type analysis

There is rotational, have HRB bearing ( ) Jiaxing bearing group sales co. , LTD. ( The company) Is bearing group co. , LTD. Established in jiaxing spot sales window, specializing in HRB brand bearings, facing the whole country, the existing stock 50 million yuan, covers the whole bearing, have very strong spot supply, is the group's retail sales center. Slewing bearing, also known as wheel bearing, can also be called slewing bearing, others say such bearings is: rotary bearing. Overall, the bearing is mainly composed of outer ring ( With teeth or no teeth) , sealing tape, rolling body ( Ball or roller) , fitting, jams, plug pin, inner ring ( With teeth or no teeth) , isolation or cage, and mounting holes ( Silk hole or light) A combination of several parts. Slewing bearing type analysis: 1. Single row four-point contact ball slewing bearing single row four-point contact ball slewing bearing is composed of two seat, compact structure, light weight, rolls four point contact ball and circular arc, can withstand the axial force and radial force and overturning moment. Rotary conveyor, welding manipulator, small and medium-sized crane and excavators and other construction machinery are optional. 2. Double rejection diameter ball slewing bearing slewing bearing has three double seat, steel ball and isolation block can be directly discharged into rolling up and down, according to the stress state, arranged up and down two different diameter of steel ball. This open assembly is very convenient, and arc raceway of bearing Angle is 90 & deg; And can bear a large axial force and overturning moment. When the radial force is greater than zero. Double axial force, raceway must be specially designed. Double rejection diameter ball slewing bearing the axial and radial size is larger, fastening structure. Especially suitable for the requirement of medium or above of the diameter of the tower crane, crane in loading and unloading machinery, etc. 3. Single row cross roller slewing bearing single row cross roller slewing bearing, is composed of two seat, compact structure, light weight, high accuracy of manufacture, assembly, small gap of installation accuracy requirement is high, the roller of 1:1 cross arranged, can withstand the axial force and overturning moment and large radial force, is widely used in lifting the transport, engineering machinery and military products. 4. Three row roller slewing bearing three row roller slewing bearing has three seat, and the radial raceway separate from top to bottom, to make each row roller load can be exactly determined. Can carry a variety of load at the same time, it is four kind of product in one of the biggest bearing capacity, axial and radial size is larger, firm structure, especially suitable for the requirements of large diameter heavy machinery, such as bucket wheel excavators, wheeled cranes, deck cranes, port cranes, molten steel operation platform, large tonnage crane machinery, etc. 5. Light light series rotary bearing slewing bearing has the same as the normal rotary bearing structure, light weight, flexible rotation, widely used in food machinery, filling machinery, environmental protection and other fields. 6. Single row four-point contact ball slewing bearing single row four-point contact ball slewing bearing is composed of two seat, compact structure, rolls four point contact ball and circular arc, is mainly used for truck crane, tower crane, excavator, car driver, engineering work, radar scanning equipment such as tilting moment, under the tendency of vertical axial force, horizontal force on the mechanical.
