Four-point contact ball slewing bearing of PRS have many types, such as single-row, double-row, four-row. There are three features: external gear, internal gear, no gear. We can supply a strong technical force and have done industrial research for many years. Rotary fulcrum bearing is a kind of large-scale bearing which can bear axial force, radial force and tilting moment of force at the same time, always with mounting hole, lubricant hole, and seal device. So it can easily make the mainframe structure compact, and it is convenient to conduct circumgyratetion, manufacture, install and maintain. Rotary fulcrum bearing includes various types, such as non-dental, inner-dental, outer-dental four points contacting ball bearing, two-bank angle contacting thrust ball bearing, cross roller bearing, and three row roller combination bearing. It is widely used in hoister transportation, mining, architecture, harbour machinery, shipping mechanism, radar machinery of high accuracy, and large-scale rotary devices on aspect of missile launcher. For further more details kindly contact us.

Slewing bearing is a kind of special bearing, which can bear combined axial, radial and tipping moment. Generally, slewing bearing is equipped with installation holes, lubricating holes and sealing devices in order to meet various requirements of main equipments in various operation conditions. Besides, slewing bearing is featured in compact in structure, convenient to guide and rotate, easy for installations and maintenance. It is widely used for rotary devices or rigging and transportation equipment, excavating equipment, port equipment, medial equipment and military equipment. slewing bearing ranges for: 1.)Four-Point Contact Ball Slewing Bearing(Outside Gear) 2.)Four-Point Contact Ball Slewing Bearing(Inside Gear) 3.)Four-Point Contact Ball Slewing Bearing(No Gear) 4.)Four-Point Contact Ball Slewing Bearing 5.)Double-Row Balls Slewing Bearing 6.)Crossed Cylindrical Roller Slewing Bearing(No Gear) 7.)Crossed Cylindrical Roller Slewing Bearing(Outside Gear) 8.)Crossed Cylindrical Roller Slewing Bearing(Inside Gear) 9.)Crossed Cylindrical Roller Slewing Bearing 10.)Three-Row Cylindrical Roller Slewing Bearing
