NTN Bearing technology has reached the world's only nanometers unit size - nano level accuracy, which in the past purely expect precision, has now begun using satellite orbits, aviation, railway and automobile, papermaking equipment, office equipment and food fields machinery and other industrial sector.It is a world-integrated precision machinery factory company, its production, sales, technical efforts of various departments to develop and deepen their professional fields, while organically combined with each other.

NTN is one of the world’s largest bearing producers. With manufacturing plants throughout the world, NTN Bearing is a leading bearing supplier to both the industrial and automotive markets.  NTN employs more than 12,000 employees in 19 countries with sales, engineering, production and service networks throughout Japan, the Americas, Europe, Asia and China.A bearing is a machine element that constrains relative movement to the desired motion and reduces KOYO 6204 Bearing friction between moving parts. The design of the bearing may, for example, provide for free linear movement of the moving part or for free rotation around a fixed axis; or, it may prevent a motion by controlling the vectors of normal forces that bear on the moving parts. Most bearings facilitate the desired motion by minimizing friction. Bearings are classified broadly according to the type of operation, the motions allowed, or to the directions of the loads (forces) applied to the parts.
