Friedrich Fischer
Friedrich Fischer (March 19, 1849 – October 2, 1899) from Schweinfurt, Germany is considered the father of the modern ball bearing, having invented the process for milling standard bearings in 1883. Biography Fischer designed the ball grinding mill, a machine that allows steel balls to be ground to an absolutely round state in large volumes for the first time. Thanks to this innovation, he laid the foundation for the entire rolling bearing industry. Thus, the worldwide success story of the ball bearing begins in Schweinfurt. Later, 1883 is officially declared the year in which the company was founded. *1890 - On July 17, Fischer received the patent for his ball grinding machine from the :de:Deutsches Patent- und Markenamt#1877 Kaiserliches Patentamt, Kaiserliches Patentamt. *1895 - The UK Imperial Patent Office grants Fischer patent number 10925A for his ball grinding and milling machine. *1896 - Fischer applies for permission to build a new plant near the train station in Sc ...

Schweinfurt
Schweinfurt ( , ; ) is a city in the district of Lower Franconia in Bavaria, Germany. It is the administrative centre of the surrounding district (''Landkreis'') of Schweinfurt and a major industrial, cultural and educational hub. The urban agglomeration has 100,200 (2018) and the city's catchment area, including the Main-Rhön region and parts of South Thuringia, 759,000 inhabitants. Schweinfurt was first documented in 791 and is one of the oldest cities in Bavaria. Around 1000 the Margraves of Schweinfurt controlled large parts of northern Bavaria. From the 12th century until 1802 Schweinfurt was a Free imperial city within the Holy Roman Empire, around 1700 a humanistic centre and in 1770 began the 250-year industrial history. During World War II, the Americans suffered their biggest air defeat over Schweinfurt in the Second Raid on Schweinfurt ''(Black Thursday)''. On 11 April 1945, the US Army invaded the city.

Germany
Germany,, officially the Federal Republic of Germany, is a country in Central Europe. It is the second most populous country in Europe after Russia, and the most populous member state of the European Union. Germany is situated between the Baltic and North seas to the north, and the Alps to the south; it covers an area of , with a population of almost 84 million within its 16 constituent states. Germany borders Denmark to the north, Poland and the Czech Republic to the east, Austria and Switzerland to the south, and France, Luxembourg, Belgium, and the Netherlands to the west. The nation's capital and most populous city is Berlin and its financial centre is Frankfurt; the largest urban area is the Ruhr. Various Germanic tribes have inhabited the northern parts of modern Germany since classical antiquity. A region named Germania was documented before AD 100. In 962, the Kingdom of Germany formed the bulk of the Holy Roman Empire. During the 16th ce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ball Bearing
A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races. The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads. It achieves this by using at least two races to contain the balls and transmit the loads through the balls. In most applications, one race is stationary and the other is attached to the rotating assembly (e.g., a hub or shaft). As one of the bearing races rotates it causes the balls to rotate as well. Because the balls are rolling they have a much lower coefficient of friction than if two flat surfaces were sliding against each other. Ball bearings tend to have lower load capacity for their size than other kinds of rolling-element bearings due to the smaller contact area between the balls and races. However, they can tolerate some misalignment of the inner and outer races. History Although bearings had been developed since ancient times, the first mod ...

Schaeffler Group
Schaeffler Technologies AG & Co. KG, also known as Schaeffler Group (''Schaeffler-Gruppe'' in German), is a German manufacturer of rolling element bearings for automotive, aerospace and industrial uses. It was founded in 1946 by brothers Dr. Wilhelm and Dr.-Ing. E. h. Georg Schaeffler. In August 2008, the firm agreed to a staggered €12 billion acquisition of larger rival Continental AG, whereby Schaeffler would defer taking a majority stake until at least 2012. However, in 2011 Schaeffler sold off €1.8 billion worth of shares of Continental, reducing its stake from 75.1% to 60.3%. Currently, the company owns 46% of Continental shares. Schaeffler Group also owns the brands INA, FAG and LuK. In Germany, the main brands of the Schaeffler Group – INA, FAG and LuK – are marketed by Schaeffler Technologies AG & Co.

19th-century German Inventors
The 19th (nineteenth) century began on 1 January 1801 ( MDCCCI), and ended on 31 December 1900 ( MCM). The 19th century was the ninth century of the 2nd millennium. The 19th century was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanding beyond its British homeland for the first time during this century, particularly remaking the economies and societies of the Low Countries, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Islamic gunpowder empires fell into decline and European imperialism brought much of South Asia, Southeast Asia, and almost all of Africa under colonial rule. It was also marked by the collapse of the large ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Engineers From Bavaria
Engineers, as practitioners of engineering, are professionals who invent, design, analyze, build and test machines, complex systems, structures, gadgets and materials to fulfill functional objectives and requirements while considering the limitations imposed by practicality, regulation, safety and cost. "Science is knowledge based on our observed facts and tested truths arranged in an orderly system that can be validated and communicated to other people. Engineering is the creative application of scientific principles used to plan, build, direct, guide, manage, or work on systems to maintain and improve our daily lives." The word ''engineer'' (Latin Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the ... ) is derived from the Latin words ("to contrive, devise") and ("cleverness").
