Single row cross roller wheel china bearings

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. Single-row four point contact china bearings turntable from the inner ring, china bearings 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, bearings for printing machine ball and isolation block can be directly discharged into the upper and lower 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. Thin section bearing Especially for applications that require above average diameter of tower cranes, truck cranes and other handling machinery. Single row cross roller wheel china bearings, composed by two seat, compact, light weight, high manufacturing precision, 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.
