Overview of Ball Bearings

Ball bearings are a kind of bearing composed of rolling bearings, which can maintain the distance between the inner ring and the outer ring of the bearing, thereby achieving smooth, high-speed movement and reducing friction.
They can bear both radial and axial loads, so they can be developed for many different applications, load types, and speeds.
Ball bearings are usually made of stainless steel, ceramic, or chrome steel, but the materials and overall design can vary greatly depending on the specific job at hand. It can also include flanges, cages, and multi-row bearings to achieve higher performance to meet specific application requirements.

Ball Bearing Types

Spark ball bearings are divided into the following categories. Spark Bearings is your preferred ball bearing supplier.
There are mainly four types of ball bearings : deep groove ball bearings, self-aligning ball bearings, angular contact ball bearings, thrust ball bearings.

Applications of Ball Bearings

There are a variety of different designs and applications for ball bearings, and their design is specific to their industrial application and load type. Some common designs of ball bearings include:
Angular Contact Bearings: designed to work under combined radial and axial loads.
Axial Bearings: also called thrust ball bearings, these are designed to work under the force applied parallel to the bearing's axis, or thrust loads.
Deep-Groove Bearings: designed to carry both radial and light axial loads.
Linear Bearings: designed to allow movement in one direction along a linear axis.
Self-aligning Ball Bearings: bearings with two sets of balls that are self-aligning and to carry both radial and light axial loads.
High-Speed Angular Contact Bearings: another type of precision ball bearing is a high-speed angular contact bearing. As the name implies, high-speed bearings are designed to handle high RPMs with precision and accuracy.
Rolling bearing
In the design of mechanical parts, rolling bearings and sliding bearings are often used. Compared with sliding bearings, rolling bearings have the following advantages and disadvantages.


(1) In general working conditions, the friction coefficient of the rolling bearing is small, and will not change with the change of the friction coefficient, and is relatively stable; the starting and running torque is small, the power loss is small, and the efficiency is high.
(2) The radial clearance of the rolling bearing is small, and it can be eliminated by the method of axial preloading, so the operation accuracy is high.
(3) Rolling bearings have a small axial width, and some bearings can bear radial and axial composite loads at the same time, with compact structure and simple assembly.
(4) Rolling bearings are standardized components with a high degree of standardization and can be produced in batches, so the cost is low.


(1) Rolling bearings have a small contact area between rolling elements and pipes, especially ball bearings, which have poor impact resistance.
(2) Due to the structural characteristics of rolling bearings, vibration and noise are relatively large.
(3) The life of rolling bearings is reduced under high-speed and heavy-duty conditions.
(4) The inner and outer rings of the rolling bearing adopt an integral structure, and cannot adopt a partial structure, which makes it difficult to install the bearing in the middle of the long shaft.
