double row cylindrical roller bearing

cylindrical roller bearing and the raceway is in line contact bearings. Load capacity, the main radial load. Rolling ring wall friction small, suitable for high-speed rotation. According to ring without ribs, it can be divided into NU, NJ, NUP, N, NF and other single row cylindrical roller bearings, and NNU, NN and other double row cylindrical roller bearing. The bearing is the inner, outer separable structure.

thrust roller bearing

roller bearing appear before spherical shape. With this roller bearings with self-aligning properties, can withstand great load. Spherical roller sub asymmetric and symmetric shape, large end generally asymmetric spherical, symmetrical surface is flat end faces at both ends. Symmetrical spherical roller child better performance, rather than the symmetrical form is eliminated. Such roller for spherical thrust roller bearing and spherical roller bearings.

single row cylindrical roller bearing

No inner or outer wall of the cylindrical roller bearing, the inner and outer ring can be relative to the axial movement, so it can be used as a free end bearings. On either side of the inner and outer double wall, rings the other side of a single row cylindrical roller bearing, can withstand a certain degree of axial load direction. General use of steel stamping cage, or copper alloy solid cage. But there are also part of the use of polyamide forming cage.

Roller bearing function

As can be seen for different reasons in different frequency corresponding to the frequency of failure tapered bearing supplier because only a small mounting structure caused when the spherical roller bearing element has manufacturing defects or serious damage to severe vibration frequency will be significantly improved .the pulse energy from the impact analysis,When the spherical roller bearing elements have tiny little damage pulse value fault with the development of the pulse value increases vibration intensity also increased split roller bearing significantly.

high precision slewing bearings

Through 50 years of construction and development of China's bearing industry has achieved a small to a great weak to strong development strategy formed the production layout is reasonable, medium high precision slewing bearings and small enterprises co-exist, relatively complete product of relatively complete industrial system. And with a larger production capacity and strong technical strength.
At present, China 's bearing industry has had a larger economic scale enterprises in the country bearing more tapered roller bearings than 1,400 employees in about 30 million people.

high precision bearings University

Mechanical Engineering Department of tapered bearing niversity Sok double rich Ph.D.Luoyang bearing Science & Technology chairman Dr. Wu paired tapered bearing  and Beijing Institute of Technology School of mechanical and Vehicular Engineering, Dr. Wang in the other four experts and scholars at the forum were on "China's bearing industry to upgrade, from large to strong roadmap" "the Present Situation and development Strategy of high-end bearing our", "the latest development of China's high-performance bearing technology", "high Performance Rolling basic research" and other major issues delivered a wonderful speech.
Part of professors and graduate students from Zhejiang, and Guangdong Province, Luoyang City, bearings and bearing related businesses and Tsinghua University, Beijing Institute of Technology, Hefei University of Technology, Henan HKUST, Xi'an high precision bearings  University.

Such bearings are separable tapered roller bearings

Paired tapered bearing the largest amount of single row tapered roller bearings. In the car's front wheels, and spend the small size of the double row tapered roller bearings. Four tapered roller bearings used in large-scale cold rolling mill paired tapered bearing other heavy machines. Tapered roller bearings are mainly exposed to the radial radial and axial load. Load bearing capacity depends on the outer ring raceway angle, angle the greater carrying capacity. Such bearings are separable tapered roller bearings , according to the number of columns bearing rolling elements into single row, double row and four-row tapered roller bearings. Paired tapered bearing bearings are separable bearings, inner and outer rings have tapered raceway. This kind of bearing according to the number of columns loaded roller is divided into single row, double row and four-row tapered roller bearings.

The show has entered the country for decades

"Dream scenery golden years have been part of the memories , but here, I can still hear the sentence 'We are confident that ' ." Yesterday , Asia's largest construction machinery exhibition Shanghai BMW Exhibition (baumaChina) at the New International Expo opening . Jubi full field lined with towering , two huge tall tires , it is difficult to cover the crossed roller bearing construction machinery industry in deep market difficulties ; while the official brochure of an exhibition with a " poetic ", then show the " quagmire " in the corporate perk intent determined to change.
The show has entered the country for decades. Has become China 's construction machinery industry benchmark . According to the current economic situation, the construction machinery angular contact bearing industry as a whole is in a period of adjustment .

roller bearing Separated

roller bearing Separated by a bearing raceway ring and needle roller and cage components , (WS) can be used with any combination punching thin raceway ring (W) or processing of thick -cut raceway ring . Non-separable bearings are precision stamping by a raceway ring and needle roller and cage assemblies maintain overall bearing constituted . This class can withstand axial load bearing . Small footprint , compact design in favor of mechanical , they use only the needle roller and cage assemblies , and the mounting surface of the shaft and housing to use as a raceway .
Tapered roller bearings with frustum -shaped roller , roller guided by the inner ring large rib . Designed to make the inner raceway, outer ring raceway and roller apex of the conical bearings for sendzimir millssurface of the rolling surfaces intersect at a point bearing center line. Single row bearings can bear radial load and axial load, double row bearings can bear radial load and axial load , suitable to withstand heavy load and shock load.

Northwest bearing plain split roller bearing products

After completion, the expected sales income 63,000 yuan, net profit of 6,150 million. With the successful implementation of the project, Northwest bearing plain split roller bearing products will be phased out, 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 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 precision bearings  project, the main plant has been completed, a full set of equipment installation and commissioning another approach, the work is well forward, 2014 will be fully debugged and tested production.

China's production of Roller bearing the vast majority

China's production of Roller bearing the vast majority of small and medium and small bearings, medium and large bearing production accounted for less than 3% in the current domestic market, high value-added precision bearing demand and large compound growth rate of around 20% in particular grinder with precision bearings, construction machinery, heavy mill large bearings, bearings and other high-tech strong market demand . 2014 domestic bearing industry 's main business revenue reached 200 billion yuan .bearing the overall industry revenue continues to grow, but Pegasus shares bearing segment operating income declined year on year , mainly due to the impact Pegasus shares of newly installed capacity of wind power industry and other factors significant decline , making wind power company , one of the leading products bearing Sales revenue fell 49.93 percent , to 368 million yuan , resulting in the company Tapered roller bearings  segment operating income decreased by 28.67% , to 1.779 billion yuan .
