BEARING DAC40740042 ZZ Product Introduction
The BEARING DAC40740042 ZZ is a high - end bearing meticulously designed to meet the complex requirements of modern industrial applications.
1. Design and Structure
Featuring a double - row structure, this bearing provides enhanced resistance to both radial and axial loads. The "ZZ" in its model name represents double - sided metal shields. These shields play a vital role in preventing contaminants such as dust, sand, and small debris from infiltrating the bearing. By maintaining a clean internal environment, the bearing can operate smoothly for a longer period, reducing maintenance frequency and costs.
2. Material
Manufactured from premium - grade bearing steel, the BEARING DAC40740042 ZZ has excellent hardness, which ensures its structural integrity under heavy loads. Its high wear resistance allows it to withstand continuous friction during operation, while the remarkable fatigue resistance enables it to endure repeated stress cycles without premature failure. This combination of material properties makes it suitable for long - term, high - intensity applications.
3. Application Areas
In the automotive industry, it is commonly used in wheel hubs and transmission systems. In wheel hubs, it can handle the high - speed rotation and variable loads during vehicle driving, contributing to stable and safe driving performance. In transmission systems, it helps to transfer power efficiently and smoothly. For industrial machinery, it is widely applied in conveyor belts, where it supports the continuous movement of heavy - duty items, as well as in pumps and compressors, ensuring their reliable operation under high - pressure conditions.
