Single-row cross roller wheel bearings, composed by the two seat, compact, light weight, high manufacturing precision, small assembly space for the installation of high precision, the roller is 1: 1 staggered, can withstand the axial forces, tilting moment and large radial force, is widely on lifting transport, engineering machinery and military products for.Triple row roller slewing bearing has three seat, up and down and radially separated from each raceway, so that each row roller loads can be determined exactly.
Bearing is the other parts on the shaft will produce relative motion, used to reduce friction coefficient during power transmission and keep the machine shaft center fixed position, its main function is to support the rotary body, in order to reduce the equipment in the transmission process of mechanical load friction coefficient. According to the motion of the frictional properties of different components, bearings can be divided into two types of rolling bearings and sliding bearings.

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.

Wheel bearing
Wheel bearings are one of the key parts of the car, its main role is to carry the weight and provide an accurate guide for the rotation of the hub, which requires that it not only can withstand axial load also bear the radial load. Conventional car wheelWith the two sets of tapered roller bearings are roller bearings or ball bearings combination, bearing installation, oiled seals and clearance adjustment is carried out in a car production line. This structure makes it difficult to assemble in the car manufacturing plant, high costs, poor reliability, and car maintenance maintenance, but also on the bearing cleaning, oiling and adjustment.
