The Ball Bearing is a type of rolling contact bearing which consists of an inner race that is mounted on the shaft or journal and an outer race that is carried by the housing or casing. In between the inner and outer race, rolling elements i.e. balls are there. Balls are used and these are held at proper distances by retainers so that they do not touch each other. The radius of the ball is slightly less than the radii of curvature of the grooves in the races providing point contact between the balls and the races. Therefore, the balls and the races may roll freely without any sliding.
Attributes:
• Cage is manufactured from either Brass or Bronze for better corrosion and wear resistance
• High load-carrying capacity in the radial as well as the axial direction
• Excellent performance in high-speed applications.
• Less frictional loss and therefore low resultant temperature rise
Applications:
The Ball Bearing is used to support and facilitate the rotation of planetary gears for efficient power transmission.
