NTN angular contact ball bearings
NTN is a comprehensive manufacturer of precision machinery, thecompany was founded in Japan in 1918, is headquartered in WestOsaka . It has 11 Japanese domestic factories, 25 operating storesand the three Institutes; It has 20 wholly foreign owned factories,two research institutes and 48 operating stores abroad. NTNproduction, sales, technical efforts of all departments develop anddeepen their own fields of expertise, but also combine mutualorganically.
NTN Precision Machining Technology and its unique proprietarytechnology in the development of long-term bearing on the basis ofaccumulated developed, and now widely used in all areas ofproduction for the use of precision machinery. This is continuallycreating new value NTN development of the new logo.
How to minimize friction coefficient and improve energyefficiency? NTN Bearing technology to the world’s only nanometersize units - nano-level precision. This past purely expectprecision, has already begun to use satellites in orbit, aviation,railway and automotive, papermaking equipment, office equipment andindustrial machinery, and food sectors in various fields.
