The main role of hub bearing is to load and provide accurate guidance for the rotation of the hub, it bears both axial load and radial load, is a very important component. The traditional automobile wheel bearings are composed of two sets of tapered roller bearings or ball bearings. The installation, oiling, sealing and clearance adjustment of bearings are carried out on the automobile production line. This structure makes it difficult to assemble in the automobile production plant, high cost, poor reliability, and the car in the maintenance point maintenance, but also need to clean, oil and adjust the bearing. Hub bearing unit is developed on the basis of standard angular contact ball bearings and tapered roller bearings, it will be two sets of bearings as one, with good assembly performance, can be omitted clearance adjustment, light weight, compact structure, large load capacity, for sealing bearings can be loaded in advance grease, omit the external hub seal and free from maintenance and other advantages, has been widely used in cars, There is also a trend of gradual expansion of applications in heavy-duty vehicles.

Precision bearing

Angular Contact Ball Bearings (Angular Contact Ball Bearings) It can withstand both radial and axial loads. Can work at higher rotational speeds. The larger the contact Angle, the higher the axial carrying capacity. The contact Angle is the Angle between the contact point connection of the ball and raceway and the vertical line of the bearing axis in the radial plane. High precision and high speed bearings usually take a 15 degree contact Angle. Under axial force, the contact Angle will increase. Single row angular contact ball bearings: machine tool spindle, high frequency motor, gas turbine, centrifugal separator, small car front wheel, differential pinion shaft, booster pump, drilling platform, food machinery, dividing head, repair welding machine, low noise type cooling tower, electromechanical equipment, painting equipment, machine slot plate, arc welding machine Double row angular contact ball bearings: oil pump, Roots blower, air compressor, various transmission, fuel injection pump, printing machinery, planetary reducer, extraction equipment, cycloidal reducer, food packaging machinery, electric welding machine, electric soldering iron, square box, gravity spray gun, wire stripping machine, half shaft, inspection and analysis equipment, fine chemical machinery
