Ball Wheel bearings

Single-row four point contact ball bearing turntable by the inner, outer, ball, isolated block of four major components, compact, light weight, ball and roller contact with a four-point arc path, can withstand the axial force, radial forces. Rotary conveyer, welding operation machine, small cranes and excavators and other engineering machinery can be selected. Double row ball bearing turntable with three seat, ball and isolation blocks can be directly discharged into the upper and lower raceway, according to the situation by force, arranged two rows of different diameter steel balls. This assembly is very easy to open, bearing raceways arc angle up and down are 90 °, can withstand great axial force and tilting moment. Double-row ball slewing bearing axial, radial dimension than the larger, structural tightening. Especially for applications that require above average diameter of tower cranes, truck cranes and other handling machinery.
