Rotary Fulcrum Bearing(three row combined roller)
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, harbor machinery, shipping mechanism, radar machinery of high accuracy, and large-scale rotary devices on aspect of missile
launcher.
