Ball Bearings – What Are They And Where Are They Used

Ball Bearings - what are they?

A ball bearing is a type of rolling element that uses balls to separate the moving parts of the bearing. The balls are usually made from steel or ceramic and are to provide frictionless movement between the different parts of the bearing. The usage of ball bearings go back to Roman times where they found them on Roman ships which were built in 40 A.D.

It was Leonardo da Vinci who first discovered the idea and the mechanics of using balls within the bearing but it was only until 1791 where Phillip Vaughn, an English carriage maker, patented the first axel to use the ball bearing.

What are ball bearings used for?

Ball bearings are more commonly used in machinery and in appliances. There are many interesting and different uses for ball bearings for example Earthquake Proof Buildings. The San Francisco International Airport uses giant ball bearings to help it withstand the effects of an earth quake. Within the airport there are over 200 columns, and each column is placed over a ball bearing with a diameter of 5 feet so in the case of an earthquake it separates the ground from the building. Once the earthquake is over the columns are centered over the balls from the force of gravity.

The different types of ball bearings

There are many different types of ball bearings including Magnetic Bearings, which are used in high speed devices. These devices can go as fast as 50,000 revolutions per minute, a normal bearing would melt or explode at this speed but the magnetic bearing can handle this. Another is the Giant Roller Bearings which are used to move very large and very heavy objects. The Egyptians first used this concept when building the pyramids and is still used today.

The World Market for Ball Bearings $325 This report was created for strategic planners, international executives and import/export managers who are concerned with the market for linear acting hydraulic power engines, motors, and cylinders. With the globalization of this market, managers can no longer be contented with a local view. Nor can managers be contented with out-of-date statistics that appear several years after the fact. I have developed a methodology, based on macroeconomic and trade models, to estimate the market for linear acting hydraulic power engines, motors, and cylinders for those countries serving the world market via exports or supplying from various countries via imports. I do so for the current year based on a variety of key historical indicators and econometric models.
