Working principle of wheel hub unit

The main function of the wheel hub bearing is to bear weight and provide precise guidance for the rotation of the wheel hub. It is a component that connects the tire, brake disc, and steering knuckle. It bears both axial and radial loads and is a critical component. According to the structure of the wheel hub, the current steel wheel hub, also known as the iron wheel hub, has a service life of about 100000 kilometers and needs to be replaced.

Common faults and solutions of wheel hub units:

Common faults:

(1) The temperature of the hub unit is too high during operation, usually due to the quality of the grease not meeting the requirements.

(2) The wheel hub unit has a slight operating sound or abnormal abnormal noise during operation.

Solution:

(1) Replace the SuKoTec high-quality wheel hub unit to prevent overheating.

(2) Check if the vehicle's mileage meets the replacement requirements, and install the hub unit correctly to avoid product damage caused by installation.

SuKoTec Hub Unit Product Advantages:

The wheel hub steel balls are made of high-grade steel balls from Japan's Chunajima G10 (with a diameter change of 0.0025mm), with a smoothness of<0.1um. The G10 grade has higher accuracy, good stability, and long service life.

The depth of the high-frequency quenching layer is 2.5 to 3.5 mm, and the quenching depth and hardness are strictly controlled to ensure the service life of the bearing.

Using Japanese Synergy AF-1 grease designed specifically for automotive wheel hub bearings, it can still be used confidently under harsh conditions (-20 ° C~170 ° C), adding extreme pressure additives and oxidation stabilizers to enhance load capacity while resisting softening and leakage.

Add a guide tooth process and use a German gear puller to shape the teeth in one cut, ensuring the tolerance requirements of the teeth and ensuring the accuracy of installation of the guide teeth.
