Ball bearing is used for low friction in rotary applications. They provide long life as they transfer the load from the balls to the inner races. Bearing are spherical in shape and have less contact with the outer and inner races resulting in the smooth action of spinning. In other words, ball bearings are a type of rolling element that maintains a separation between the moving parts of the bearing. Sometimes, the bearing manufacturer lubricate the bearing to last for the full operating life span.
Ball bearing or bearings are used in a wide range of machine goods for rotary action. From electrical fans to air conditioners, from motor cars to bicycles, bearing is used in all kinds of machines -be it small or big. Bearing supports the rotary part of the machine and reduces the friction, and thus enables smooth operation. Bearing manufacturer make it in different sizes to fit in a large factory machine to a small wrist watch.
There are four main parts of a bearing
- The outer ring
- The inner ring
- The steel balls or the rolling elements.
- A cage or the ball separator or retainer.
Radial ball bearing and angular are designed in such a way that they are perpendicular to the position of axis. The rolling elements carry the load. They rotate around the inner race and distribute the load on to the raceways. The separator, as the name suggests acts as a barrier between the two and prevents them from bumping into each other.
The main function of the bearing is to facilitate smooth functioning of the axis. The good bearing manufacturer is the one, that can maintain ultra precision in the groove where the ball rolls in a circle. The bearing manufacturer are making bearing to be used in Cooling fans, personal computers, telecommunications, home electronics, automation and medical industries.
History of bearing manufacturer- The history of the bearing is as old as 1500 years when bearing was made to reduce friction. Leonardo Da Vinci discovered ball bearing to reduce friction in the horse drawn carts.
There are two types of ball bearing manufacturers
- Radial ball Bearing
- Thrust ball Bearing
Radial ball bearing is also known as deep groove bearing support to axis loads of different degrees. They are designed to support loads which are parallel to the axis. They consist of an inner ring, outer ring, balls, and a cage to separate the balls. They carry both radial and axial loads.
Thrust bearing have two rings of equal size. These are designed in such a way to carry pure thrust loads only. They cannot carry any radial load. They are also not fitted in a cage, but are mounted on a shaft to a seating surface. The rolling element could be a needle, a roller or a ball. The inner and the outer rings have integral gears. The thrust bearing is also known as turntable bearings, and tabletop bearings. Then there are Precision Ball Bearing, High Precision ball Bearings, Super Precision, Super High Precision and Ultra precision ball bearings. These are all factory definitions that tell about the tolerance and Precision levels.
There are different bearing manufacturers depending on the load handling capacities of the bearing radial ball. It primarily carries radial loads only. Primary axial load is carried by Thrust ball bearing. A combination of both radial and axial loads is carried by angular contact ball bearing.
In case one needs assistance in choosing the right precision bearing for any particular application, there are design engineering and application assistance services to make your choice easier. There are bearing manufacturers who can satisfy a variety of operating conditions and different precision requirements.
