 The ASAHI Asahi Seiko Co., Ltd. was established in 1928, initially only the production of bearings. In 1951, the production began in Japan with Bearings manufacturer, is currently the LNSERTED Japanese professional bearing manufacturer. Since then, as a pioneer, the company is committed to develop standardization and quality standards for Pillow Block Bearings. 
 After 1975, the company began producing other new products, such as linear motion products. In the industrial sector, ASAHI is bearing now has become a trusted brand ASAHI Asahi Seiko Co., Ltd., Japanese professional LNSERTED bearing manufacturer. Convinced that the professional is the best, is committed to provide users with the full range, quality and cheap products. 
 The type of the LNSERTED bearing bearing, angular contact bearings: ball and rings of nominal contact angle greater than 0 °, but less than 90 ° of rolling bearings. Both radial load and axial load. In high speed work. The greater the contact angle, the higher the axial load carrying capacity. High precision and high-speed bearings usually take the contact angle of 15 degrees. The effect of axial force, the contact angle will increase. 

 LNSERTED bearing type: 

 1), with a tight set screws spherical UC class of bearings; 
 2), with a tapered hole in the spherical UK class of bearings; 
 NSK Bearings three quality standards and detection technology 

 First, the structural design is reasonable and is equipped with advanced nature, will have a longer NSK bearing life. The manufacture of bearings generally have to go through a multi-channel processing such as forging, heat treatment, turning, grinding and assembly. The rationality of the process, advanced, stability will also affect the bearing life. Which affect the quality of the finished bearing, heat treatment and grinding processes, often have a more direct relationship with NSK bearing failure. In recent years, studies show that the metamorphic layer on the bearing surface grinding process with NSK bearing surface quality is closely related.

 Second, NSK bearing metallurgical quality of the materials used to early failure of the main factors of influence Rolling. Metallurgical technology (such as advances in bearing steel vacuum degassing, etc.), raw material quality is improved. The proportion of the raw material quality factor in the failure analysis of NSK Bearings has decreased significantly, bearing but it is still one of the bearing failure of the main factors. 
 Third, selection of the adequacy remains the NSK bearing failure analysis must be considered. NSK Bearing failure analysis of the main tasks is based on a lot of background material, analysis of data and failure modes to identify the main factors that cause bearing failure, so that in a targeted manner of service, proposed improvements, extending bearing to avoid bearing the occurrence of sudden of early failure. Installation conditions are the primary factor in the use of factors, one of NSK Bearings are often due to installation of inappropriate changes lead to the stress state of the entire NSK Bearings each part, NSK Bearings in the normal state operation and early failure. 
 The cage effect: 
 A guide and promote the rolling element rolling in the right raceway; 
 2, cage rolling element equidistant separated cloth to prevent the work in the raceways on the circumference for rolling bodies collide with each other and friction; 
 3, in the separation of bearings, rolling element and a ring together to prevent the rolling body off.

 Bearing, called the window used to isolate and guide a rolling element, pocket hole clearance to keep the aircraft in the radial and axial certain activity, the total volume of activity is called radial cage clearance. The roller cage variety of structure types, complex shape. Cage equidistant pocket Kong, the shape of the pocket hole spherical, circular, oval, rectangular and tooth type, its size is larger than the size of the rolling element, the difference between a pocket hole clearance, and sometimes the needle rolling part of the connection between the cage window is called the beam, does it connect and increase the role of cage strength.
