Genuine A820203000040 Bearing Housing with 1 Year Warranty

PEODUCT DESCRIPTION

Support and fixation - providing the "framework"
This is the most fundamental function of the bearing housing. Through fasteners such as bolts, it securely installs the entire bearing assembly (including the bearing, shaft, and seals) at the specific position of the pump truck (such as the hinge points of the boom, the mixing system, and the rotating mechanism), providing a stable and reliable support foundation for the rotating components.
2. Carrying and transmitting loads - Acting as the "force transmission path"
When the pump truck is in operation, the bearings need to bear extremely large and complex loads:
· Radial load: The force perpendicular to the axis, generated by the weight of the boom, the weight of the concrete, and the motion inertia, etc.
· Axial load: In certain parts, such as the swing axis of the S-shaped valve, there will be a thrust along the axis direction.
The function of the bearing seat is to bear these forces from the bearings and safely distribute and transfer them to the larger and more robust frame or structural components of the pump truck, preventing stress concentration that could lead to local damage.
3. Ensure rotational accuracy and alignment - act as a "precision platform"
The inner hole of the bearing housing serves as the installation base for the outer ring of the bearing. A high-precision bearing housing can ensure:
The bearings are precisely aligned and fixed to prevent eccentricity or skewing.
The shaft can rotate stably around its theoretical centerline, reducing eccentricity and vibration.
This is crucial for ensuring transmission efficiency, reducing vibration and noise, and prolonging the lifespan of all related components (the shaft, bearings, seals).
4. Protection and Sealing - Building the "Safe House"
The bearing housing forms a relatively enclosed space, working in conjunction with sealing components such as oil seals and dust shields, to achieve:
· Maintain lubrication: Keep the grease or lubricating oil inside the bearing to ensure continuous lubrication.
· Prevent contamination: In the harsh construction environment of a pump truck (filled with cement dust, sand, and rainwater), the bearing housing is the first line of defense against these abrasive contaminants from entering the bearing interior. Once contaminants enter the bearing, they will quickly wear down the raceways and rolling elements like sandpaper, leading to the failure of the bearing.
