Introduction
The double row angular contact ball bearings typically use balls as rolling elements. However, there are bearings that incorporate both balls and rollers.
These bearings are often used in applications such as machine tool spindles, gearboxes, and other precision equipment where both radial and axial loads need to be supported, and the design allows for higher load capacities and better performance under certain conditions.
The roller double row angular contact ball bearing (LR50 series) has a reasonable structural design and adopts a double row angular contact ball design, which can withstand large axial and radial loads. At the same time, the inner ring and outer ring of the bearing are in contact with the roller and cage respectively, giving the bearing high stability and long service life.
It has strong load-bearing capacity and can withstand large axial and radial loads under high-speed operation conditions. This makes the bearing suitable for use in various high-precision, high-load mechanical systems, such as CNC machine tools, industrial robots, etc.

Roller double row angular contact ball bearings LR52 LR53 (3057, 3067, 3058, 3068) series have smaller friction resistance, which helps to reduce the energy consumption and temperature of the mechanical system. At the same time, the friction coefficient of the bearing is stable, which can ensure that the mechanical system maintains stable performance during long-term operation.
Roller double row angular contact ball bearings have high rotation accuracy, which helps improve the motion accuracy and stability of the mechanical system. At the same time, the bearing can automatically align and adapt to the assembly requirements of various spindles, making the mechanical system less prone to deviations and vibrations.
Roller double row angular contact ball bearings are suitable for various mechanical systems, such as machine tools, textile machinery, printing machinery, packaging machinery, etc. At the same time, the bearing can adapt to different working envisronment temperature and humidity conditions, and has wider adaptability.
