Long-Life High Speed Auto Rear Wheel Hub Bearing Dac25520037 25X52X37 mm tapered roller bearing auto bearing for auto parts

Wheel hub bearing is a device that is designed to enable the smooth rotation of the wheel hub around the axle while supporting the weight of the vehicle or machinery and handling various forces acting on the wheel, such as radial and axial loads. It consists of inner and outer races, rolling elements (like balls or rollers), and a cage to hold the rolling elements in place. It can reduce friction and ensure the efficient transfer of power and motion between the axle and the wheel, contributing to the overall stability, safety, and performance of the vehicle or equipment.

Wheel hub bearings are key components in the automotive chassis system, performing three primary functions:

1. Weight support: They connect the wheels to the suspension system, bearing the vehicle's own weight and dynamic loads.

2. Friction reduction: Their precision ball/roller structure ensures smooth, low-resistance wheel rotation.

3. Precise guidance: They maintain wheel alignment, ensuring driving stability and steering response.

Wheel Hub

Wheel Hub Bearing

The hub unit is a device that fills an important role in supporting a car by the wheels, and integrates the bearings and the surrounding components. There is one type of hub unit that rotates smoothly while supporting the vehicle weight, and another type that transmits the driving force from the engine to the wheel. Because the hub unit has a large effect on vehicle performance, it is required to have both durability on rough roads and a high degree of accuracy.

Structure
In the past, wheels on cars used a combination of two radial ball bearings or tapered roller bearings. With the increasing integration of the wheel bearing and the surrounding components, we have now reached a point where the "3rd generation" of hub units have been put into practical use.

Auto Parts

1st-generation hub unit
The outer rings of two single-row bearings are integrated with each other, the unit is greased and sealed. There are two types: DAC, which uses balls, and DU, which uses tapered rollers.

2nd-generation hub units

Short base pillow (plummer) block ball bearing units consist of an insert bearing mounted in a cast iron housing. This variant has threaded holes for attachment bolts and is suitable for applications where the direction of rotation is constant or alternating. It has an inner ring extended on both sides and is locked onto the shaft by tightening two set screws on the inner ring, making it easy to mount. The units are compliant with Japanese Industrial Standards.

3rd-generation hub unit
This is a further development on the 2nd-generation hub unit. These hub units have an integration of the hub shaft and inner ring on the outer side (tire side) of the inner ring rotation type, and the number of 3rd-generation hub units with built-in high-performance sensors is growing. For driven wheels, the method of fastening the hub shaft and inner ring with nuts has been changed to the "shaft end clinching" method.

Built-in ABS sensors
In order to improve car safety, the installation of an ABS (anti-lock brake system) that controls the brakes has become widespread, and hub units with built-in sensors equipped with a wheel rotation system have been used to reduce the size and weight, in addition to the process being simplified.

Low Noise

Long-life working time

High Precision

The hub unit is required to have "both lower fuel consumption and superior driving performance," "high reliability," and "high capacity," and these are incorporated into each component.

Achieving both lower fuel consumption and superior driving performance, where lower fuel consumption means a reduction in weight and superior driving performance means both strength and rigidity at a high level

High reliability, even in severe environments such as driving on muddy roads, is ensured.

The high-capacity bearing design is enabled by maximizing the use of allowable space.
