NSK Ltd was founded on November 8, 1916 and is headquartered in Tokyo, Japan. Bearings are one of the staples of industry. The origins of the Japanese bearing industry, can be traced back to the completion of the first prototype by Nippon Seiko Limited Partnership Company in 1915. Full-scale production of the bearings needed to drive the development of the Japanese machinery industry commenced with the establishment of NSK Ltd. NSK bearings has a long history of involvement in aviation. Since NSK first started producing bearings in Japan in 1916, as a Japanese bearing pioneer, it has developed and supplied various types of bearings, and has made great contributions to the development of the industry and technological progress.
NSK bearing products are mainly applied in the following fields: automobile, motor (motor), gear device, injection molding machine, machine tool, mining machinery, construction machinery, motorcycle, office equipment, paper machine, pumps and compressors, railway, semiconductor, metallurgical equipment, wind generators,etc. Bearing NSK 120BTR10STYNDBLP4A online , pls click here :
Seiko Japan has announced that it has developed a new method of manufacturing high-strength materials and using cold-roll forming to manufacture bearings for wheel hub assemblies for passenger cars. Compared with hot forging, cold forging can increase strength, but requires several times of forming pressure during processing. The company uses the "side extrusion method" to form large-area flanges with a small pressure to achieve forming at a low pressure.
In order to ensure the reliability of strength and the like while achieving light weight, customers' requirements are getting higher and higher. Compared with the previous hot forging, cold-rolled forming can improve the strength due to improved work hardening and surface finish. After the strength is improved, the disc flange can reduce the weight by 30% by changing the shape, etc., thereby reducing the overall hub assembly by more than 15%. However, cold rolling is more difficult to process than hot forging. Aiming at the problem of increasing forming pressure, the flange part is pressed after pressing down the shaft part, thereby reducing the area of ??the forming part. Squeeze the shaft with a smaller area to form a flange with a larger area. The area where pressure is applied throughout the processing process has not changed.
