What is an Angular Contact Ball Bearing?
ACBB or angular contact ball bearing is a type of ball bearing, that is useful for carrying axial as well as radial loads. They are suited for high accuracy as well as high-speed performance applications.
Construction fo Angular Contact Ball Bearings
ACBB is made up of the following parts-
- Inner Ring
- Outer Ring
- Rolling Element: Steel Balls
The line of contact between the races and ball is angular- around 25 to 40 degrees. Higher the angle of contact, the higher load- thrust, it can carry
Following parameters need to be considered while selecting the bearing
- Static Load: It is the maximum radial load that a bearing can take up without permanent deformation.
- Dynamic Load: It is defined as the constant radial load that a group of identical bearings with stationary outer rings can take up to withstand a life of 1 million revolutions of inner ring.
- Rated Speed: It is lower for a bearing with greased lubrication as compared to the one with oil lubrication.
Often the ACBB- Angular Contact Ball Bearings selected with shield or seals has a slower speed as compared to the ones used without any seals. Seals play a vital role in protecting the bearing from foreign impurities as well as containing the lubricant inside the bearing.
Diversification of Angular Contact Ball Bearings
There are many types of angular contact ball bearings available in various designs and sizes like :
1.Single row angular contact ball bearings
They can hold axial loads at one direction only. A single row ball bearing is particularly designed to adjust against another ball bearing. The ball bearings cannot be separated and they typically have one high shoulder and one low shoulder. The low shoulder allows a huge number of balls to be added in bearings. This allows for high load carrying capacity relatively.
2.Double row angular contact ball bearings
The designs of double-row bearings co-relate with two single row angular contact ball bearings. They are arranged back to back. Unlike single bearings, they have less axial space and can bear radial loads along with axial loads. The loads can be accommodated for both sides. They are also able to tolerate tilting moments.
3.Fixed section angular contact ball bearings
The bearings have extremely thin rings. They have specific series regardless of the size of the ball bearing. The main features of fixed contact bearings are extreme stiffness and lightweight.
Advantages of ACBB- Angular Contact Ball Bearings
- These bearings can withstand heavy radial and axial loads
- They are capable of withstanding angular misalignment of shafts as well
Applications of Angular Contact Ball Bearings
Angular contact ball bearings are engineered for use in high-speed, high precision applications for :
- General industry
Operating Life of an Angular Contact Ball Bearings Machine
The life of a bearing is dependent upon the number of revolutions or the number of operating hours at a given speed which it can withstand before the metal fatigue occurs. The metal fatigue can occur on the raceway of the inner or outer ring or on the rolling element. The general reasons that contribute towards failure of a bearing are abrasive wear, moisture, improper mounting, corrosion, improper shaft/housing fits, skidding of rolling elements and failure due to lubrication systems.
