Friedrich Fischer
Friedrich Fischer (March 19, 1849 – October 2, 1899) from Schweinfurt, Germany Germany, officially the Federal Republic of Germany, is a country in Central Europe. It lies between the Baltic Sea and the North Sea to the north and the Alps to the south. Its sixteen States of Germany, constituent states have a total popu ... 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. His innovation was to tilt slightly the grinding wheel by 1.9°, forcing the balls to rotate on both their axis while they are ground. 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Schweinfurt
Schweinfurt ( , ; ) is a town#Germany, city in the district of Lower Franconia in Bavaria, Germany. It is the administrative centre of the surrounding Schweinfurt (district), 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 it became a centre of Renaissance Humanism, humanist activity, and in 1770 the city's 250-year industrial history began. During World War II, the Americans suffered their biggest air defeat over Schweinfurt in the Second Raid on Schweinfurt ''(Black Thursd ...

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. Common ball bearing designs include ''angular contact, axial, deep-groove,'' an ...

19th-century German Inventors
The 19th century began on 1 January 1801 (represented by the Roman numerals MDCCCI), and ended on 31 December 1900 (MCM). It was the 9th century of the 2nd millennium. It 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, expanded beyond its British homeland for the first time during the 19th century, particularly remaking the economies and societies of the Low Countries, France, 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 Catholic Church, in response to the growing influence and power of modernism, secularism and materialism, formed the First Vatican Council in the late 19th century to deal with such problems and confirm ce ...

Engineers From Bavaria
Engineers, as practitioners of engineering, are professionals who invent, design, build, maintain and test machines, complex systems, structures, gadgets and materials. They aim 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 , the origin of the Ir. in the title of engineer in countries like Belgium, The Netherlands, and Indonesia) is derived from the Latin words ("to contrive, devise") and ("cleverness"). The foundational qualifications of a licensed professional engineer typically include a four-year bachelor's degree in an engineering dis ...
