Bearing disc

       In the automotive braking system, the bearing disc and brake disc are two key components that each perform different functions but work together to ensure the safe braking of the vehicle. This article will explore in detail the technical characteristics and application scenarios of bearing discs and brake discs.
       1、 Bearing discs: technical features and functions
       1. Definition and Function
       Bearing discs, commonly known as wheel hub bearings, are critical components that connect wheels and axles. It not only supports the weight of the wheels, but also ensures that the wheels can rotate smoothly and efficiently. The main functions of the bearing disc include:
       Supporting wheels: bear the weight of the wheels and various loads during driving.
       Reduce friction: Reduce friction between the wheel and axle through rolling elements such as balls or rollers.
       Ensure smooth rotation: Provide precise rotational support to ensure smooth operation of the wheels.
       2. Technical features
       High precision manufacturing: Bearing discs require high-precision manufacturing processes to ensure their stability and reliability during high-speed rotation.
       Material selection: High strength steel or alloy materials are usually used to withstand high loads and long-term use.
       Sealed design: Adopting a sealed design to prevent dust and moisture from entering, extending the service life.
       Lubrication system: Built in lubrication system ensures that the bearings maintain good lubrication during operation.
       3. Application scenarios
       Bearing discs are widely used in various types of vehicles, including cars, trucks, and construction machinery. They are an important component of the vehicle's driving system, ensuring that the wheels can rotate smoothly and efficiently.
       2、 Brake discs: technical features and functions
       1. Definition and Function
       The brake disc is a key component in the car braking system, which achieves deceleration and stopping of the vehicle through friction with the brake pads. The main functions of brake discs include:
       Provide braking force: generate braking force through friction with brake pads to slow down or stop the vehicle.
       Heat dissipation performance: During the braking process, the brake disc needs to effectively dissipate heat to prevent thermal attenuation.
       Wear resistance: Good wear resistance is required to extend the service life.

       2. Technical features
       Material selection: Cast iron or high-performance alloy materials are usually used to provide sufficient strength and wear resistance.
       Heat dissipation design: By designing ventilation holes or heat dissipation slots, the heat dissipation performance is improved and thermal attenuation is reduced.
       Surface treatment: Adopting perforation or marking design to improve braking force and thermal attenuation resistance.
       Lightweight design: By optimizing structural design, such as split structure, weight is reduced and vehicle handling performance is improved.
       3. Application scenarios
       Brake discs are widely used in various types of vehicles, including sedans SUV、 Trucks and racing cars. They are the core components of the vehicle braking system, ensuring that the vehicle can brake safely and reliably under various driving conditions.
