very in line with Slewing bearing national industrial policy

the major resources into high value-added " large , high-speed , precision ," R & D and production of high-end bearings , very in line with national industrial policy , comply with the current economic , policy orientation. This will not only be able to expand its market share in the Northwest bearing production scale and product , help the company to return to the first tier bearing enterprises , but also to promote the overall development high precision bearings and progress of China's bearing industry to some extent .
Li Shuming said Northwest bearing invest 188 million yuan of annual output of 200,000 sets of building rail bearing project , the main plant has been completed, a full set of equipment installation and commissioning another approach , the work is Sealed bearing well forward, 2014 will be fully debugged and tested production . In 2014 , the company will focus on improving product mix and increasing technological content of products , and promote high-end bearing construction projects, and other high- margin products increased variety, so that the gradual transformation of the company's existing manufacturing bearings to high-end equipment manufacturing. The non-public offering if the company successfully implement the project , the Northwest bearing the full force of China's high-end bearing market , the fundamentals of the company will be completely changed

Slewing bearing downstream industrial agglomeration and development in Ningxia

According to Mr. Li Shuming Northwest bearing , general manager of introduction, Northwest Bearing developed "2.5MW wind power generation equipment spindle bearings " project, designed to meet the requirements of the user MWT-2500A (2.5MW) direct drive wind turbines. Can not only improve the company's own income , but also effectively promote Roller Bearing the local wind power equipment, downstream industrial agglomeration and development in Ningxia , and promote the formation of the wind power industry development and industry chain , has far-reaching implications for Ningxia industrial restructuring, transformation of economic growth mode ; company developed the " heavy-duty vehicle nose cone bearing " project, in addition to improving the company's revenue , but also by dump truck with a nose cone clutch bearings  development, open -highway heavy-duty dump truck bearings supporting the localization market ; company developed " Metro ( light rail ) development and application of bearings " project , if successfully implemented, can promote China's subway cars bearing domestic work , breaking the monopoly of foreign technology , reduce procurement costs and improve the ability to self- repair , revitalize national industry, to promote the development of China's rail transportation equipment manufacturing and upgrades.
Insiders said that before the 1990s, Northwest bearing bearing industry has been one of the national key enterprises , the scale of production in the fourth digit industry

Have a conical taper roller bearing inner ring and outer ring raceway

Tapered roller bearing mainly bear radial primarily diameter, the axial load. Bearing capacity depends on the Angle of the outer ring raceway, the greater the Angle, the greater the carrying capacity. The separated type bearing is a bearing, according to the Slewing bearing the number of columns of the scroll body can be divided into single row, double row and four row circular cone roller bearings. Single row tapered roller bearing clearance to users in the installation adjustment; Double row and four row circular cone roller bearings clearance has according to user requirements for a given when the products leave the factory, not the user.
Have a conical taper roller Rolling mill bearing inner ring and outer ring raceway, the tapered roller are arranged in between. All projection line on the surface of the cone axis bearing the same points together. This design make the taper roller bearing is especially suitable for composite (radial and axial load. Bearing axial load capacity is mostly determined by the contact Angle alpha; Alpha Angle is larger, the higher axial load capacity. Angle size by calculating coefficient of e; E value, the greater the contact Angle, the greater the bearing axial load of the greater applicability.

Slewing bearing with excellent impact resistance

With appropriate hardening depth , meticulous organization , appropriate surface hardness and core hardness of infiltration of carbon bearings , thrust bearing steel than using spherical roller bearings with excellent impact resistance , the general chemical infiltration of carbon bearing steel ingredients. <BR> Punched retainer material , the use of low high precision bearings carbon steel. Depending on the application , use brass, stainless steel plate. Cutting cage material , the use of high strength brass, carbon steel , in addition, also the use of synthetic <BR> thrust spherical roller bearings are generally manufactured through forging , heat treatment, turning, grinding and assembly of multi-channel processing processes. The reasonableness of the processing technology , advanced, will also affect the stability of the bearing life . Which affect the quality of the finished gimbal Rolling mill bearings heat treatment and grinding processes, tend to have a more direct relationship with the failure of the bearing. Recent studies of spherical roller thrust bearing surface modification layer showed a close bearing surface grinding process and quality . <BR> Spherical roller thrust bearing life analysis of the main tasks is based on a lot of background material , analysis of data and failure modes , identify the main factors that cause bearing failure , so that puts forward improvements to extend bearing service period , to avoid spherical roller thrust bearings early occurrence of sudden failure
