The BEARING DAC39740039 ZZ is a high - performance bearing, precisely engineered to meet the complex and demanding requirements of diverse industrial applications.

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 represents double - sided metal shields. These shields serve as a reliable defense, effectively blocking dust, dirt, and other contaminants from infiltrating the bearing. This ensures a clean internal environment, enabling long - term smooth operation. With an inner diameter of 39mm, an outer diameter of 74mm, and a width of 39mm, its well - proportioned dimensions contribute to its reliable 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 may be equipped with an innovative internal clearance adjustment mechanism, allowing it to adapt to different operating temperatures and rotational speeds.

Manufactured from top - grade alloy steel, the BEARING DAC39740039 ZZ offers remarkable strength and durability. The alloy steel, with its carefully calibrated 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.

In the automotive industry, it is well - suited for critical components such as the wheel hubs of small - sized cars or entry - level 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. It also plays a crucial role in the transmission systems of these vehicles, efficiently transmitting power and torque.

In the industrial equipment sector, it is an essential component in precision - lathe machines. It can support the accurate positioning and smooth rotation of the lathe spindle, contributing to the production of high - precision turned parts. It is also widely used in small - scale automated production lines, where it enables the continuous and stable operation of conveyor belts and small - sized robotic arms, ensuring the efficient operation of the entire production process. In addition, it can be found in some light - duty industrial machinery, such as printing presses, where it helps to maintain the smooth operation of the rotating components.
