paired tapered bearing rebar awarded the successful development and production .

Tonghua Iron and Steel Group has successfully developed high-speed wire rod production HRB400E
November 21 , Shougang Tonghua  Slewing bearing Iron and Steel Group through high-speed wire rod plant new lines of production HRB400E8 mm rebar 42 99.7 tons , HRB400E8 mm rebar awarded the successful development and production .
It is understood , HRB400E test seismic reinforcement steel is rolling temperature requirements are very strict, new product development is currently under trial production stage. The production is the fourth rolling plant this year, but also the largest number of rolling , the best one, spinning temperature first drops 900 ℃, changing the spinning temperature is not lower than the previous record of 1000 ℃ for .
In the organization of production Stainless steel slewing bearing process, production department and rolling mill plant personnel to develop a reasonable plan rolled repeatedly revised operating points , the technical personnel at the scene to track the guidance requires workers reasonable control roller speed to ensure open rolling temperature , temperature and spinning into the finishing temperature , strengthen

paired tapered bearinginspection of rolling  groove , guide and guard the entrance , timely adjust the size of the finished wire , seismic steel products to ensure customer requirements for dimensional accuracy , quality assurance pruning to ensure end to end water cooling and defective parts are not all clean and trim so storage product quality to meet market and customer needs .
It is reported that the feedback data center sampling technique from watching the indicators uniformity , yield strength and tensile strength are up to quality requirements.

may cause the rolling element and the raceway between the sliding destructive

In order to ensure Slewing bearing satisfactory performance , needle roller / angular contact ball bearings like all ball bearings and roller bearings , must always bear acting on the radial and axial certain minimum load , especially if they want to run at high speed or subjected to high accelerations or rapid changes in the load direction . Under these conditions , the rolling element and the inertia force of the retainer and lubricants friction bearing arrangement may play a deleterious effect on the rolling conditions , and may cause the rolling element and the raceway between the sliding destructive .
Increase in radial needle bearing backing bearings on the necessary minimum radial load can be estimated using the following formula :
Frm = 0.02 C
Angular contact ball bearings necessary minimum axial load can be calculated using the following formula :
Where
Cold start or lubricant viscosity is very high, even demanding loads. Bearing weight of the components together with external forces generally exceed the minimum necessary load. If this is not the case, you must give Needle roller / angular contact ball bearings impose additional radial and / or axial loads.

Azam company became the sole agent in Bangladesh ceremony Azam Enterprise general manager Dhaka , said : "NSK two major areas of industrial and agricultural monthly demand of around 2 billion worth Kata bearings , Azam became the exclusive distributor of NSK Bangladesh help to improve buyer confidence in us , Azam Enterprise company mainly engaged in well-known national brands of bearings, has 35 years of history, has become the exclusive distributor in Bangladesh NSK , NSK Bearings responsible for regional sales in Bangladesh , and Azam within a year the company plans to set up sales elsewhere center

which makes the cost reduction, the company brings considerable benefits

Swedish SKF Group Headquarters capacity to adjust
SKF bearings distributor in China sales center edit, Sweden, SKF Group's official website revealed that in March 2010, the Swedish SKF Group successfully implemented adjustment which is located in Gothenburg, Sweden, headquarters of the production Roller bearing capacity, the program is expected to involve about 150 people, realignment of headquarters capacity costs about 90 million kronor.
 It is reported that last year, the Swedish SKF Bearing Group headquarters to face the financial crisis and lower market demand for capacity to try to carry out adjustments based solution, which makes the cost reduction, the company brings considerable Precision bearing benefits. Implemented in March this year to adjust capacity based program package costs about 90 million Swedish kronor, will be credited to the income statement for the first quarter. These initiatives will be held no later than the third quarter of 2010, fully implemented, is expected to be generated when the gains of SEK 50 million.
 Swedish SKF Group realignment of headquarters staff capacity in order to avoid redundancy, while weak demand for consultation by the union representatives of the solutions successfully implemented last year to prove that the solution can be kept core skills and avoid production interruptions.
