Double row ball aligning ball bearing  

Spherical roller bearings are a common type of rolling bearing, consisting of an inner ring, outer ring, rolling elements, and a cage. They have the ability to self-align, allowing them to work even when the installation is not precise or when there are deviations in the bearing housing, reducing the complexity of the installation process. Both the inner and outer rings of spherical roller bearings are spherical in shape, allowing the bearing to maintain balance when subjected to large radial and axial loads. Compared to other types of rolling bearings, spherical roller bearings have a higher radial load capacity and can withstand certain axial loads. The rolling elements of spherical roller bearings are spherical balls, which design enables the bearing to have low friction and high rotational speed. Additionally, spherical roller bearings have good self-lubrication properties, effectively reducing friction and wear during high-speed operation. Spherical roller bearings are widely u…
