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.
4. Technical Parameters
Parameter | Value |
Inner Diameter (mm) | 40 |
Outer Diameter (mm) | 74 |
Width (mm) | 42 |
Dynamic Radial Load Rating (kN) | 50 |
Static Radial Load Rating (kN) | 35 |
Maximum Rotational Speed (rpm) | 6000 |
To sum up, the BEARING DAC40740042 ZZ is an ideal choice for
industries that demand high - quality bearings. Its advanced
design, top - notch materials, and excellent performance make it a
reliable component for various applications, providing stable
support and efficient operation.
