SINOTRUK HOWO center bearing AZ9319313260

Description

SINOTRUK HOWO center bearing AZ9319313260 install location ：

The center bearing AZ9319313260 is usually installed within or beneath the crossbeam of the heavy truck axle frame. Some are fixed in the crossbeam using bolts, while others are suspended beneath the crossbeam. It is generally located at the bottom of the vehicle, and the specific position may vary depending on the vehicle model.

However, it is usually positioned in the middle or near the middle of the transmission shaft, serving to support the transmission shaft and reduce its vibration and oscillation during operation, ensuring the rotational positioning of the front and rear transmission shafts, while allowing for a slight oscillation of the front transmission shaft and a small axial movement. The center bearing AZ9319313260 is suitable for models such as HOWO T5, T7, SITRAK, and MAN light trucks.

Structural features of the center bearing AZ9319313260:

1. Crossbeam connection part: The transmission shaft hanger is fixed to the crossbeam of the frame. The crossbeam connection part of the hanger is provided with adjustment holes. Two adjacent adjustment sub-holes are connected vertically, allowing the installation position of the hanger in the height direction to be adjusted.
2. Transmission shaft connection part: It is connected to the intermediate support of the drive shaft. The installation hole is a straight slot hole, and its length direction is consistent with the length direction of the pro shaft connection part, facilitating the elimination of errors in the length direction of the transmission shaft and achieving the connection with the intermediate support component of the transmission shaft.
3. Hanger body: It is the main supporting structure of the transmission shaft hanger, usually located in the middle position, and plays the role of supporting the transmission shaft. Some hanger bodies are an integrated structure with the side plate and are connected to the rubber bearing support of the intermediate transmission shaft.
4. Ball bearings and bearing housing: The bearing housing is used to install the ball bearings. The transmission shaft passes through the rolling bearings, which can reduce the friction and resistance during the rotation of the transmission shaft, making the rotation of the transmission shaft smoother.

The material of the center bearing AZ9319313260:

1. Material: Generally, it uses ductile iron (such as QT450-10) or cast steel (such as ZG230-450).
2. Ductile iron: It has high strength, toughness and wear resistance, can withstand the alternating loads and vibrations during the operation of the transmission shaft, and has a relatively lower cost, suitable for manufacturing components that withstand impact and wear.
3. Cast steel: It has higher strength and rigidity, excellent impact resistance, and is suitable for heavy-duty vehicles (such as HOWO T7, SITTAK, etc.) with higher requirements for structural strength.
4. The material of the bearing is high-carbon chromium bearing steel, with surface quenching treatment (hardness HRC60-65), possessing high wear resistance and fatigue strength, ensuring stability during long-term high-speed operation.

The characteristics of the AZ9319313260 material for the transmission shaft hanger:

1. High strength and wear resistance: The combination of cast iron/cast steel body and bearing steel can withstand the high-load operation of the transmission shaft under heavy vehicle loads, reducing component deformation and wear.
2. Shock absorption and buffering: The elastic design of rubber pads can effectively absorb the vibration and impact of the transmission shaft, reducing the noise of the transmission system and improving driving comfort.
3. Weather resistance and corrosion resistance: Surface treatment (such as bolt galvanization, rubber anti-aging formula) enables the components to adapt to the rainy, muddy and oily environments in complex road conditions, extending the service life.

Maintenance and servicing of the center bearing AZ9319313260:

Regularly check whether the fixing bolts of the center bearing AZ9319313260 are loose. If they are loose, they should be tightened promptly. At the same time, pay attention to the lubrication condition of the bearings. According to the vehicle’s maintenance manual, regularly replenish lubricating oil to the bearings to reduce wear and prevent bearing damage due to lack of oil. If cracks appear in the transmission shaft bracket, aging of the gasket pad, or looseness of the bearings are found, they should be replaced in time to ensure the normal operation of the transmission shaft and the safety of vehicle operation.
