AI Technical Summary
In existing technologies, the number of balls is limited by the clearance between the inner and outer rings of the bearing, which affects the stability of the bearing during use.
The bearing adopts a combined splicing inner ring design, which increases the number of balls and improves the limiting effect by installing multiple balls on the inner side of the outer ring of the bearing and using an annular slide and cage to install the balls at equal angular intervals. Combined with the detachable retaining ring and inner ring splicing structure, the bearing increases the number of balls and improves the limiting effect.
This increases the number of balls that can be placed inside the bearing, enhancing the stability of the bearing during use and the ease of assembly.
