DAC458242 ABS bearings are angular contact ball bearings. These bearings are designed to bear both radial and axial loads. The contact angle is critical; while a larger contact angle enhances axial load capacity, it may reduce the maximum permissible speed of the bearing.
As a vital component of the vehicle, the wheel hub bearing supports the wheel and ensures smooth rotation under various loads, including vehicle weight, road vibrations, and braking forces. The integrated ABS function incorporates a wheel speed sensor, providing accurate rotation data to the vehicle's ABS and ESP systems for enhanced safety and stability.
Proper lubrication is essential to minimize friction and wear. Common methods include grease and oil lubrication. It is important to select the correct viscosity: inadequate viscosity increases friction and heat, while improper oil supply can negatively impact the bearing's operational speed.
These bearings feature integrated sensors or signal generators. This design may slightly alter the rotational inertia and weight of the bearing. To ensure optimal performance of the ABS system, the bearing must operate within specified speed ranges to allow accurate wheel speed measurement.
