The main function of a hub bearing is to bear weight and provide precise guidance for the rotation of the hub. It bears both axial and radial loads and is a very important component.
The front wheel bearing is a cylindrical ball bearing, which is press fitted into the front wheel steering knuckle during installation. The hub head is then pressed into it and transmitted through the hub spline and transmission shaft contact. The rear wheel bearing and hub are an integral unit (i.e. the rotatable thing that connects the tire), with an internal structure consisting of a circle of ball bearings.
dissimilarity! The wheel hub bearing unit refers to the bearing, which is a set of bearings related to the wheel hub. Sedans, most light and medium-sized trucks, and some heavy-duty trucks are composed of two bearings; A car wheel hub unit refers to a component composed of a wheel hub and at least two bearings, including bearings.
Bearing steel is different from stainless steel in that it has higher requirements for materials and processes. The driving noise is very loud after replacing the new bearings. After excluding other reasons, the front noise is loud, there is a problem with the front wheel bearing, and the rear noise is loud, which may be a problem with the rear wheel bearing. Good bearings won't make a lot of noise.
The first generation wheel hub bearings are double row angular contact ball bearings or double row tapered roller bearings with integral outer ring and back-to-back combination inner ring. To ensure that the pre load after installation is within the specified range, the initial bearing clearance is pre-set, and there is no need to use a spacer to adjust the pre load on the automotive assembly line.
What is the difference between wheel hub, wheel rim, and wheel rim? Wheel hub is also known as wheel rim. In the past, single row tapered roller or ball bearings were most commonly used for automotive wheel hub bearings. Three generations of wheel hubs have been developed: the first generation was composed of double row angular contact bearings. The second generation has flanges used to fix bearings on the outer raceway.
