INA NTN NSK TIMKEN Bearings factory 鈼?Introduction
NSK roller bearings are produced by NSK Corporation. Founded in 1916, NSK is headquartered in Tokyo, Japan. In the field of bearings, NSK ranks first in Japan and ranks in the forefront of the world. NSK has established a sales network with nearly 70 factories in 24 countries and regions around the world. Since 1992, NSK started to invest in production in China, and it has established more than 20 production, R&D, sales companies and its subsidiaries in China. We maintain a good cooperation with NSK and can distribute NSK roller bearings.
NSK bearings are widely used in auto parts, precision machinery products, electronic application products and other fields.
鈼?Bearing Series
The types of the bearings include deep groove ball bearings, angular contact ball bearings, pillow block bearings, needle roller bearings, spherical roller bearings, cylindrical roller bearings, track rollers, radial insert ball bearings, spherical plain bearings, rod end bearings and linear bearings.
鈼?Production Details
鈼?Cage manufactured by injection molding
Put the directly empty dry granular engineering plastic in the dry barrel, melt it into a semi-liquid state by heating with a resistance wire, and pressurize it with a plunger or a moving screw, so that the semi-liquid raw material is injected from the nozzle into the forming mold of the injection molding machine. After heat preservation and cooling, the required cage is obtained. Its technological characteristics are: the cage is injection-molded at one time, which can obtain precise geometric shape and dimensional accuracy and low surface roughness value. High production efficiency without machining: simple mold and injection molding. The bearing is easy to assemble and easy to realize automatic control. the plastic cage has good properties such as wear resistance, anti-magnetic and low friction.
However, due to the defects of thermal deformation, aging and embrittlement of the plastic itself, as well as some problems in the cage structure and injection molding process, the application of the plastic cage is limited.
鈼?The main purpose of forging of bearing rings
In order to obtain the hair damage similar to the product shape, thereby improving the utilization rate of metal materials and reducing the amount of machining. eliminating the inherent defects of the metal, improving the metal structure, making the metal streamline distribution reasonable and good density, thereby improving the service life of the bearing.
According to the temperature of the metal during forging, forging is divided into three categories: hot forging, cold forging and warm forging. The forging process in which the metal is heated above the recrystallization temperature is called hot forging. The deformation of metal at room temperature is called cold forging. The metal deformation between hot forging and cold forging is called warm forging. The most widely used processing method is still hot forging.
鈼?Bearing Plastic Deformation Failure
Under the action of external force and ambient temperature, the partial plastic flow or the overall plastic deformation on the surface of the bearing parts causes the failure of the sleeve bearing to work normally, it is called plastic deformation failure. It includes cage warpage, plastic scratches, indentation.
