Angular Contact Ball Bearings

Double row angular contact ball bearing

Description：

Double row angular contact ball bearings can bear combined radial and axial loads at the same time. It consists of two rows of balls, usually separated by a nylon or brass cage, with inner and outer raceways designed to allow contact angles in both directions. This design enables the bearing to support axial loads in both directions as well as radial loads. Double row angular contact ball bearings are available in open and sealed designs, as well as different cage materials and accuracy classes to meet different application requirements. They are often used in pairs or sets to support higher axial loads or provide greater rigidity and accuracy in applications where precise shaft positioning is critical.

Angular Contact Ball Bearings Industry knowledge

Why is the load-bearing rigidity of Double row angular contact ball bearing so strong?

1. The unique feature of double-row angular contact ball bearings lies in their double-row design, which allows the bearings to effectively resist axial loads and overturning moments while bearing radial loads. Compared with single-row bearings, double-row angular contact ball bearings are structurally more stable and can withstand greater loads. The double-row design also increases the contact area of ​​the bearing, thereby improving the bearing's load-bearing capacity and rigidity.

2. Double row angular contact ball bearings are usually made of high-strength, high-hardness materials, such as high-carbon chromium bearing steel. These materials have excellent mechanical properties and wear resistance and can maintain their performance under high load and high speed conditions. Stable performance. High-quality material selection provides a solid material foundation for double-row angular contact ball bearings, further enhancing its load-bearing rigidity.

3. The contact angle of double row angular contact ball bearings is another significant feature. The contact angle refers to the angle between the inner ring and the outer ring raceway of the bearing, which determines the load-bearing capacity and rigidity of the bearing. The contact angle of double row angular contact ball bearings is generally larger, which makes the contact area between the raceways larger when the bearing is under load, thus improving the bearing capacity and rigidity. The larger contact angle also helps Reduce the friction and wear of the bearing during operation and extend the service life of the bearing.

4. In addition to structural design, material selection and contact angle characteristics, the installation and use of double-row angular contact ball bearings are also important factors that affect their load-bearing rigidity. Correct installation can ensure that the matching clearance between the bearing, shaft and housing is appropriate and avoid vibration and noise caused by too large or too small clearance. Reasonable preload setting can also improve the load-bearing capacity and rigidity of the bearing. During use, regular lubrication and maintenance of bearings are also key measures to maintain their load-bearing rigidity.

5. Double-row angular contact ball bearings are widely used in various high-precision, high-load mechanical equipment due to their strong load-bearing rigidity. In CNC machine tools, precision instruments, aerospace and other fields, double-row angular contact ball bearings are used plays a vital role. These fields require extremely high bearing capacity and rigidity, and double row angular contact ball bearings have become the preferred bearing type in these fields due to their excellent performance.
