NSK exhibitors 2010 Beijing China International Exhibition Coal

Seiko Corporation of Japan (NSK LTD.) On October 26 -29 days participating in the Beijing National Agricultural Exhibition at the 2010 China International Coal Fair, here is the distributor of NSK China's reported. 2010 China International Exhibition, organized by the State Coal Mine Safety Supervision bearing manufacturers, the National Energy Administration, China Coal Industry Association co-sponsored by the State Administration of Production Safety Supervision and Management Center for International Cooperation contractor, the theme was "safe and efficient mining, green carbon use." In addition to showcasing the exhibition changing the mode of development of coal industry's achievements in scientific and technological innovations of coal enterprises, the main show coal production, preparation and processing, mine construction, coal transportation, coal mine safety, geological exploration, coal chemical industry, mine explosion Double roller bearing aspects of advanced technology and equipment. Exhibition 2010 Beijing China International Exhibition Coal origin of the Chinese, the United States, Britain, Japan, Australia and other countries and regions, more than 10 research institutions and numerous famous. As the world's largest bearing manufacturer Seiko Co., Ltd., one of Japan (NSK), also participated in the exhibition. And exhibited a series of devices, bearing as many of the core components of mining machinery, almost throughout all the equipment in the field. 2010 Beijing China International Exhibition on Coal, NSK exhibited a series of mine and all kinds of Bearings NSK Bearings special installation tools, test equipment, in-kind exhibition and novel video presentation attracted up to 2,000 people, the number of daily visitors to visit, a total of issue various samples sent up to 1,555 books, by the visitors alike.By NSK exhibitors 2010 Beijing China International Exhibition Coal, NSK with more exhibitors had extensive experience and information exchange, consolidate and develop more win-win partnership. The exhibition on the further development of NSK, has played a catalytic role.

Double row cylindrical roller bearings are divided into two forms:

     ⑴ NN0000 type double row cylindrical double roller bearing
     The bearing structure is compact, small deformation under load, it is particularly suitable for machine tool spindle bearing. Its outer wall, so you can install the outer ring and the inner components, respectively (with roller and cage), does not limit the axial displacement of shaft or housing, the same size and radial single row cylindrical roller bearings , can withstand greater radial load.
     ⑵ NN0000K type double row tapered bore cylindrical Slewing bearing
     This kind of bearing structure is compact, small deformation under load and therefore suitable for machine tool spindle bearing. Bearing bore is tapered to micro adjust the radial clearance.
     This kind of bearing outer ring without ribs due, it can be installed separately outer and inner components (with roller and cage), does not limit the axial displacement of shaft or housing, the same size and radial single row cylindrical roller bearings compared to withstand greater radial load.
