Ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races.
Ball bearings tend to have lower load capacity for their size than other kinds of rolling-element bearings due to the smaller contact area between the balls and races. However, they can tolerate some misalignment of the inner and outer races.
There are several common designs of ball bearing, each offering various performance trade-offs.
Deep groove ball bearings
Angular contact ball bearing
Self-aligning ball bearings
Axial thrust ball bearings
They can be made from many different materials, including stainless steel, chrome steel, and ceramic (silicon nitride, Si3N4). A hybrid ball bearing is a bearing with ceramic balls and metal races.
Deep groove ball bearings are the most widely used bearing type and are particularly versatile.
They have low friction and are optimized for low noise and low vibration which enables high rotational speeds.
They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than other bearing types.

ApplicationIt can be used for parts that rotate at high speed with low friction torque and for all applications that require low noise and low vibration, like toy,small power tool, robot, vacuum,fish reel, 3d printer.
Thrust bearings are designed to accommodate axial load in one or both directions. The single acting carries the load in one direction while the double acting can carry the load in both directions. There are several design types and configurations for thrust bearings to suit a variety of load capacities and applications.
A self-aligning ball bearing is ideal for applications in which the shaft and housing are misaligned. Designed to accommodate a three-degree misalignment, self-aligning ball bearings minimize friction and frictional heat. Due to the relatively small contact angle, axial load capacities of these bearings are lower than, for example, that of angular contact bearings. There are many applications for self-aligning ball bearings, including mining, food processing and mass production, such as in the textile industry.
Angular contact ball bearing is a type of bearing designed to handle both thrust and radial loads. Angular contact ball bearings have an outward and inward ring that are relatively displaced to each other, thus allowing them to bear the weight of combined loads.
Due to the way they are designed, angular contact ball bearings are wonderful for carrying and accommodating combined loads.
The most commonly used angular contact ball bearings designs are:
Single row angular contact ball bearings
Double row angular contact ball bearings
Four-point contact ball bearings.
