For what ball bearing is used?

A ball bearing is a type of rolling-element bearing that serves three main functions while it facilitates motion: it carries loads, reduces friction and positions moving machine parts. Ball bearings use balls to separate two “races,” or bearing rings, to reduce surface contact and friction across moving planes.

Why were ball bearings so important in ww2?

German bearing manufacturers had a long history of manufacturing bearings in Schweinfurt, and their production during World War II made them a target for American bombings. Bearings were a vital component in the tanks, airplanes, machine guns, heavy artillery, and submarines used by the belligerents during the war.

What are three things that use ball bearings?

Standard office equipment such as photocopiers, fax machines and printers all use bearings such as needle bearings and deep groove ball bearings and you will even find small ball bearings in the hard drive of your computer.

Why is ball bearing used in machinery?

Use in machines: The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads. Ball bearings reduce the friction so that machinery can work smoothly. The sliding friction gets converted to rolling friction which is much less and power dissipation is reduced.

How important are ball bearings?

The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads. Because the balls are rolling they have a much lower coefficient of friction than if two flat surfaces were sliding against each other.

What household items have bearings?

Household Appliances Ball bearings are used in refrigerators, air conditioning units, ovens, dishwashers, generators, washing and drying machines, microwaves, blenders, ceiling fans, vacuum cleaners, food processors, and even in kitchen or bathroom drawers.

Why do bearing fail?

The majority of bearing failures occur because of improper lubrication. Lubrication failure can occur if the wrong lubricant is used, if not enough lubricant is applied, or if the bearing has been exposed to excessive temperatures that have caused the lubricant to degrade. Corrosion & Contamination.

What kind of guns relied on ball bearings?

Likewise, the German MG 34 and MG 42 machineguns relied heavily on ball bearings. Cars, trucks, anything that (mechanically) moves, including bicycles, need ball bearings. Torpedoes, ships, airplanes, most artillery, many bombs and artillery ammunition – all need ball bearings.

Why did the US bomb the ball Bering factories?

America’s plan was to bomb key ball bering factories which accounted for a large percentage of German ball bering production to exasperate the perceived German shortage. Factories in and around Schweinfurt accounted for a significant amount of German ball-bearing production.

What kind of weapon is a nail bomb?

The nail bomb is also a type of flechette weapon. Such weapons use bits of shrapnel (steel balls, nail heads, screws, needles, broken razors, darts and bits of metal) to create a larger radius of destruction.

Where did ball bearings in Germany come from?

Factories in and around Schweinfurt accounted for a significant amount of German ball-bearing production. The Kugelfischer plant produced 22 percent, and the Vereinigte Kugellagerfabriken I and II produced 20 percent, and another one percent came from the Fichtel & Sachs factory.
