Self-aligning ball bearing
Product Name: Self-aligning ball bearing
Product ID: W
Product Description: Self-aligning ball bearing
details:
The self-aligning ball bearing has two rows of just seeking, the inner ring has two raceways, and the outer ring raceway has an inner spherical shape, which has the property of self-aligning. It can automatically compensate for the coaxiality error caused by the shaft's slip and the housing deformation, and is suitable for the parts that support the seat hole and cannot guarantee strict coaxiality.

The middle bearing is mainly subjected to radial load and can withstand a small amount of axial load while being subjected to radial load. It is usually not used to withstand pure axial load, such as bearing a pure axial load, and only one row of rigid balls is stressed.
