Hyundai Kia Cars Bearing Assembly Korean Series Cars 52750-0U000 Wheel Hubs For Elantra VERNA

Quick details :

Product Description:

A hub bearing is an assembly of several components, housed within a metal or composite hub that is connected to the vehicle's axle or spindle. It serves to provide a mounting point for the wheel and keep it in the proper alignment. Common parts of the hub bearing include an outer and inner ring, a set of rolling elements, a retainer or cage, as well as seals and shields for protection.

The outer ring is generally made of steel or aluminum alloy and is connected to the axle. The inner ring is linked to the rotating part of the axle or spindle, and is designed to rotate against the outer ring. The set of rolling elements, typically in the form of metal balls or rollers, are put between the two rings and enable the hub bearing to bear the weight of the car and for smooth rotation. The retainer or cage, commonly made of metal or synthetic material, prevents the rolling elements from making contact with each other and drastically reduce friction. Last, but not least, seals and shields are used to secure the lubricating grease found inside the bearing, and ward off possible contaminants like dirt and debris.

Hub bearings come in a range of sizes and shapes for different vehicles. For certain models, such as those with ABS or traction control systems, they may include integrated sensors that help the vehicle's control system to detect the precise wheel speed.

Periodic inspection and the necessary maintenance of hub bearings is vital to make sure that they are running properly and securely, without the risk of abnormal wear. Any signs of unusual noise, play, or vibration suggest that it is time to have a qualified automotive professional assess the hub bearing.

Features:

Integrated Sensor: Hub bearings can feature an integrated sensor for certain control systems such as ABS (Anti-lock Braking System) or traction control. These sensors provide real-time data on wheel speed which the control systems can use to regulate braking and traction accordingly.

Sealed Design: Some hub bearings come with a sealed design, which helps protect the internal components from dirt, water and other debris. This sealing feature aids to preserve the lubricating grease, reducing the risk of premature wear or damage.

Pre-Set Greased: Time-saving is attainable with pre-greased hub bearings which come already filled with the appropriate amount of lubricating grease from the manufacturer. This makes installation easier and also increases the performance of the bearing.

Durable Materials: Hub bearings are typically made of sturdy materials such as steel or aluminum alloy in order to better cope with the wear and forces of vehicle operation.

Integrated Hub Assembly: Most hub bearings are available as a complete assembly featuring the hub, bearing and other components that must work together seamlessly. This design simplifies installation and performance.

Easy Installation: Installation of a hub bearing is a simplistic process due to the pre-drilled mounting holes and bolt patterns that coincide with the vehicle's hub or spindle. This makes the replacement process easier and removes the need for heavy tools or equipment.

OEM Equivalency: Quality aftermarket hub bearings can be used to replace the original equipment as they offer the same specifications, dimensions and performance as the original bearings to ensure proper fitment and complete compatibility with the suspension system.

Corrosion Resistance: Some hub bearings may have a special coating to enhance their resistance to corrosion. This is due to rust and corrosion caused by exposure to various elements such as moisture, road salt etc. which threaten the longevity and performance of the bearing if not countered.

Noise Reduction: For a quieter and smoother driving experience, certain hub bearings have noise-reducing features such as precision engineering or specialized design, applied by advanced sealing techniques. This minimizes vibrations and noises.

Technical Parameters:

The hub bearing assembly is an important component of a vehicle, as it allows the wheel assembly to rotate freely while also providing support for the braking system. When selecting a hub bearing, there are several key specifications to consider, which can vary depending on the vehicle's design.

Outer Diameter: This dimension determines the fitment and compatibility with the vehicle's hub or spindle. The size specification should match the corresponding outer diameter of the wheel assembly.

Inner Diameter: The inner diameter refers to the size of the bore of the hub bearing assembly, which should match the axle diameter of the vehicle for proper installation.

Width/Thickness: The overall thickness of the assembly should correspond with the wheel assembly for a correct fitment.

Bolt Pattern: The number and spacing of the mounting bolt holes should be compatible with the vehicle's hub or spindle.

Flange Type: Some hub bearings have flanges that provide mounting points for the brake disc or rotor. These can vary by vehicle, and may be 4-bolt or 5-bolt flanges.

Load Capacity: This indicates the maximum load a hub bearing can safely support. It should match or exceed the requirements of the vehicle.

Material: Hub bearings are constructed from high-quality materials such as steel or aluminum alloy, and the specific material composition may vary by manufacturer.

Seal Type: Different seal types are available, such as rubber seals, metal shields, or integrated seal designs, and this affects the level of protection from contaminants.

Lubrication: Hub bearings may require extra greasing during installation and should be properly maintained per the manufacturer's guidelines.
