BEARING DAC38710039 ZZ Product Introduction
The BEARING DAC38710039 ZZ is a high - performance bearing, painstakingly designed to meet the complex and demanding needs of diverse industrial applications.
1. Design and Structure
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 represents double - sided metal shields. These shields serve as a reliable defense, effectively blocking dust, dirt, and other contaminants from infiltrating the bearing, thus ensuring a clean internal environment for long - term smooth operation. With an inner diameter of 38mm, an outer diameter of 71mm, 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 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 DAC38710039 ZZ offers outstanding 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.
3. Application Areas
Automotive Industry
In the automotive industry, it is well - suited for crucial components such as the wheel hubs of compact cars or small - displacement engines. These vehicles often operate under diverse 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 vital role in the engine's rotating components, efficiently transmitting power and torque. For example, in some fuel - efficient cars with small - displacement engines, this bearing can support the smooth operation of the engine's crankshaft and camshaft, reducing energy loss and enhancing overall performance.
Industrial Equipment Field
In the industrial equipment sector, it is an essential component in precision - milling machines. It can support the accurate positioning and smooth rotation of the milling spindle, contributing to the production of high - precision machined parts. In small - scale automated production lines, it enables the continuous and stable operation of conveyor belts and small - sized robotic arms, ensuring the efficient operation of the entire production process. Additionally, in some light - duty industrial machinery like food - processing equipment, it helps to maintain the smooth operation of the rotating parts, ensuring product quality and production efficiency.
