Wheel Hub Bearing Double Row Angular Contact Ball Bearing DAC25520042

Product Description

DAC25520042 Wheel 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. Hub bearing unit is developed on the basis of standard angular contact ball bearings and tapered roller bearings, it wil be two sets of bearings as one, with good assembly performance, can be omitted clearance adjustment,light weight, compact structure, largeoad capaclty, for sealing bearings can be loaded in advance grease, omit the external hub sedl 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.
