BEARING DAC42800045 ZZ Product Introduction
The BEARING DAC42800045 ZZ is a high - performance bearing, precisely engineered to meet the complex and demanding requirements of a wide array of industrial applications.
1. Design and Structure
This bearing features a double - row structure, ingeniously designed to handle both substantial radial and axial loads with great efficiency. The "ZZ" in its model indicates double - sided metal shields. These shields act as a reliable defense, effectively blocking dust, dirt, and other contaminants, ensuring a clean internal environment for long - term smooth operation. With an inner diameter of 42mm, an outer diameter of 80mm, and a width of 45mm, its well - proportioned dimensions contribute to its excellent load - bearing capacity. The internal components are precisely configured to evenly distribute forces, minimizing stress concentrations and ensuring seamless operation under various working conditions. Additionally, it might be equipped with an advanced internal clearance adjustment mechanism, allowing it to adapt to different operating temperatures and rotational speeds.
2. Material
Manufactured from top - grade alloy steel, the BEARING DAC42800045 ZZ offers remarkable strength and durability. The alloy steel, with its carefully formulated composition, provides high hardness, enabling the bearing to withstand heavy - duty loads during operation. Through advanced heat - treatment processes, its wear resistance is significantly enhanced, allowing it to endure continuous friction over extended periods without significant wear and tear. Moreover, the alloy steel exhibits excellent fatigue resistance, enabling the bearing to endure repeated stress cycles over a long time, making it an ideal choice for high - intensity and long - term applications.
3. Application Areas
Automotive Industry
In the automotive industry, it is well - suited for crucial components such as the wheel hubs of mid - sized sedans or crossover vehicles. These vehicles often operate under various road conditions, and the bearing can handle the high - speed rotations and variable loads during driving, ensuring a stable and safe driving experience.
Industrial Equipment Field
In the industrial equipment sector, it is an essential component in high - precision milling machines. It can support the accurate positioning and smooth rotation of the milling spindle, contributing to the production of high - quality machined parts. It is also widely used in automated assembly lines, where it enables the continuous and stable operation of conveyor belts and robotic arms, ensuring the efficient operation of the entire assembly process.
