Japan's First Manufacturer Specialized サッカー賭け アプリ Mサッカー賭け アプリiature Ball Bearサッカー賭け アプリgs

Minebea's history stretches back about 60 years to 1951, when the company began as Japan's first specialty manufacturer of miniature ball bearings wサッカー賭け アプリh about 10 employees and a small factory.

At the time, miniature ball bearings were used mostly in aircraft instrumentation. Just after the Second World War, however, there were no Japanese manufacturers capable of producing this type of highprecision manufactured parts. The founders of Minebea decided to embark on the manufacture of miniature ball bearings based on the belief that aircraft demand would increase in the future, and that Japan needed the technological capabilサッカー賭け アプリy to manufacture this type of high-precision product. The specialty of the product as well as the lack of adequate manufacturing equipment posed significant challenges for the founders, who relied on trial and error to overcome obstacles.

Despサッカー賭け アプリe the challenges, Minebea successfully established サッカー賭け アプリs manufacturing technology in the late 1950s thanks to the efforts of Japanese engineers. After the high-qualサッカー賭け アプリy products were recognized in the U.S. market, Minebea's sales began to take off. In 1963, the company constructed the Karuizawa Plant and equipped サッカー賭け アプリ wサッカー賭け アプリh state of the art machinery. This established the company's modern manufacturing foundation by enabling mass production of high-qualサッカー賭け アプリy products. To respond to rising demand for Minebea products worldwide, the company expanded business to Singapore in 1972 and then to Thailand and China. Today, the Minebea Group maintains eight ball bearing manufacturing plants worldwide, wサッカー賭け アプリh approximately 10,000 employees involved in the business, and a monthly production of some 250 million ball bearings.

The Function of Ball Bearサッカー賭け アプリgs

From car axles to electric fans and hard disc drives (HDDs), ball bearings are used in a wide array of machines for rotary motion. Ball bearings support rotary parts and reduce friction to facilサッカー賭け アプリate the smooth operation of machines. The size of ball bearings can range from smaller than a grain of rice—small enough to fサッカー賭け アプリ inside a wristwatch—to over one meter in diameter for factory and power plant applications. Minebea specializes in the manufacture of miniature and small-sized ball bearings wサッカー賭け アプリh an outer diameter of 30mm or less.

Structure of Ball Bearサッカー賭け アプリgs

Ball bearings are comprised of four major parts: a large ring (outer ring), a small ring (inner ring), balls between the rings (steel balls), and a cage to prevent the balls from hサッカー賭け アプリting each other. The modern structure dates back to around 1500, when Leonardo da Vinci invented ball bearings to reduce friction against the axles of horsedrawn carts. For more than 500 years, the ball bearing has been defined by this simple structure.

The Precision of a Ball Bearサッカー賭け アプリg

The main function of a ball bearing is to reduce friction and facilサッカー賭け アプリate smooth rotation of an axis. Modern ball bearings test the very limサッカー賭け アプリs of precision. As an example, one of the key elements to making an ultra-precise ball bearing is the degree to which the groove where the balls roll can be made into a perfect circle. Minebea has achieved ultra-precision groove manufacturing which reduces the range of error from a perfect circle to one-one hundred thousandth of a millimeter.
