Roller Double Row Angular Contact Ball Bearings
Roller Double Row Angular Contact Ball Bearings 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.
