A Ball Bearing is used to reduce friction and support rotating or oscillating shafts. It consists of an inner and outer ring with a set of balls in between. The outer ring is the stationary part of the bearing and provides support and protection for the inner parts. The inner ring is the rotating part of the bearing and is mounted on the shaft. It provides a smooth surface for the balls to roll on.

Attributes:
• Can handle heavy radial and axial loads
• Designed to withstand shock loads and vibrations

Applications:
A Ball Bearing facilitates the smooth and efficient movement of rotating or oscillating parts in hydraulic lines.
