Brand NSK Hub Bearing 39KWD02 Auto Wheel Sizes

1. Specifications:

Wheel hub bearing's main function is to provide accurate guide for the rotation of the wheel hub, it carry axial load, and bear radial load, is a very important component.Wheel hub bearing unit is in the standard angular contact ball bearings and tapered roller bearings, on the basis of it will be two sets of bearing as a whole, the advantages are the assembly performance is good, can omit clearance adjustment, light weight, tight structure, and load capacity is big, can first fill grease when sealed bearing, omit the external wheel hub seal and no maintenance etc, and has been widely used in cars, in a truck also has a tendency to gradually expand the application.

2. Application:

DAC wheel Hub Bearings are double row angular contact ball bearings.

Wheel bearings (hub bearing) main role is to load and for the rotation of the hub to provide accurate guidance, both axial load radial load again, is a very important component. Traditional automotive wheel bearing is composed of two tapered roller bearings or ball bearings combination, bearing installation, oiled, and adjust the clearance seals are conducted in automotive production line.

3. Features:

Wheel hub bearings (hub bearing) is mainly used for the rotation of the wheel hub bearing and provide precise guidance, it is under axial load and bear radial load, is a very important parts. Traditional car wheel with bearing is by two sets of tapered roller bearing or ball bearing combination and become, bearing installation, oil, seal and clearance adjustment are in the car on the production line. This structure makes it in the car factory assembly difficulty, the high cost and poor reliability, and the car maintenance station maintenance, also need to bearing for cleaning, oil and adjustment. Wheel hub bearing unit is in the standard angular contact ball bearings and tapered roller bearing developed on the basis of, it will be two sets of bearing assembly as an organic whole, have good performance, can be omitted the clearance adjustment, light weight, compact structure, load capacity, for sealed bearing can advance in grease, ellipsis external hub seal and from maintenance etc, and has been widely used in cars, in truck also.
