ferris wheel bearing Wheel bearing

Wheel bearings can withstand a large axial load, radial load and overturning moment, comprehensive load, set support, large bearing rotation, transmission, fixed and other functions in one particular structure. Wheel bearings

Single-row four point contact mobile crane bearing‍ ball

Single-row four point contact ball bearing turntable from the inner ring, outer ring, ball, isolated block of four major components, compact, light weight, ball four point contact with the circular rolling road, can withstand the axial force, radial forces. Rotary conveyors, welding operation machine, small cranes and excavators and other construction machinery can be selected. Double-row ball bearing turntable has three races, ball and isolation block can be directly discharged into the upper and lower worm gear speed reducer‍ raceway, according to the situation by force, arranged up and down two rows of balls of different diameters. This assembly is very convenient, carrying angle of both the upper and lower circular raceway is 90 °, can withstand large axial forces and tilting moments. When the axial force is greater than 0.1 times the radial force, roller must be specially designed. 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. Single row cross roller wheel bearings, composed by two seat, compact, light weight, high manufacturing precision, Deep groove ball bearing‍ small assembly space for installation high precision roller 1: a cross arrangement, can withstand axial force, tipping moment and larger radial force, is widely on lifting the transport, engineering machinery and military products are used.
