The BEARING DAC47820057.5 ZZ is a high - performance bearing, precisely designed to meet the complex and demanding needs of diverse industrial applications.

This bearing features a double - row structure, expertly engineered to handle both substantial radial and axial loads with remarkable efficiency. The "ZZ" in its model indicates double - sided metal shields. These shields act as a reliable safeguard, effectively keeping out dust, dirt, and other contaminants, ensuring a clean internal environment for smooth operation over a long lifespan. With an inner diameter of 47mm, outer diameter of 82mm, and width of 57.5mm, it has a robust size - design that contributes to its load - bearing capacity. Its internal components are precisely configured to evenly distribute forces, minimizing stress concentrations and enabling seamless operation under various working conditions. Additionally, it may be equipped with an internal clearance adjustment mechanism, allowing it to adapt to different operating temperatures and rotational speeds.

Manufactured from top - grade alloy steel, the BEARING DAC47820057.5 ZZ offers outstanding strength and durability. The alloy steel is carefully formulated to provide high hardness, enabling the bearing to withstand heavy - duty loads during operation. Through advanced heat - treatment processes, its wear resistance is further 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.

In the automotive industry, it can be applied in crucial components like heavy - duty vehicle wheel hubs. These wheel hubs need to endure high - speed rotations and variable loads during driving, and this bearing can ensure a stable and safe driving experience. In the industrial equipment field, it is well - suited for large - scale construction machinery such as cranes. In cranes, it can support the heavy - duty operation of the boom and slewing mechanisms, handling the large - scale forces generated during lifting and rotation. It is also an essential component in some high - precision industrial equipment, ensuring accurate positioning and smooth rotation.
