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 Slewing Bearing 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. 2011 China's bearing manufacturing industry to realize an annual industrial output value of 193.211 billion yuan , an increase 27.59% ; sales revenue of 191.097 billion yuan year on year increase of 30.30% ; total profit of 12.523 billion yuan year on year increase of 26.54% at present precision bearings and other basic mechanical casting industry has . a national focus on the development of " second five" industry and strive to reach or approach international advanced level. Under the support of the policy is expected to end in 2015 bearing the foundry industry sales reached 222 billion yuan or so . China's bearing production is expected to total sales of over 22 billion sets of more than 350 billion yuan is expected to become the world's largest bearing manufacturing and sales base. So late bearing steel market outlook optimistic .

Cylindrical roller bearing Near to Shanghai Yuan customers often reflect their relatively new chain hoist selection confused

Near to Shanghai Yuan customers often reflect their relatively new chain hoist selection confused , I do not know how to choose the right type of chain hoists . For this new specially Shanghai Yuan summarize a few points in this for our customers choose chain hoist models specified when needed attention.
1 , understand their purchase of Slewing Bearing the brand chain hoists purposes. Whether regular use ? The maximum required number of pounds of chain hoists to pull ? And will tell Yuan 's new sales staff, they can recommend several suits your needs chain hoists model for you.
2 , has its own heart can withstand the price, whereby you can make a choice in the domestic chain hoists and chain hoists imported into , of course, does not necessarily imports than domestic well.
3, according to the above two points , after filtration , is also available for the rest of the chain hoist model we choose so few , and this time we have to do is to test the mechanical Stainless steel slewing bearing properties of the final product , to see whether the product through the National Crane detection transport machinery quality supervision and Inspection Center , through inspection and in a little over cases still work to prove that subsection model reliable quality chain hoists , chain hoists the trusted brand .
After the above three we will find that the selection is so simple chain hoists , chain hoists other is in the process of selection must not be too hasty in order to avoid careless buy inferior products , to later use safety hazard .

Roller Bearing the pulse energy from the impact analysis

Spherical roller bearing vibration signal analysis and diagnosis by spectral analysis of rolling bearing vibration signal can discover hidden reasons of precision rolling bearing fault diagnosis
1, from the point of view of the frequency
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 .
2 , 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.
3 , monitoring methods
For the spectrum can be used to determine whether the device is relatively normal criteria
Lubrication time interval has a simple premise : The spherical roller bearings to keep the equipment running without reasonable and crashes due to dry conditions and stop running . This is a fixed concept of prevention . However, we must maintain a balance and a lot of excessive thirst lubrication lubrication between .
Traditionally, the lubrication plan is based on the time given . Equipment suppliers to develop normally lubricated plan based on operating time. And equipment suppliers are often added to the amount of lubricating oil in their maintenance program to guide the process .

use and maintenance repair and other maintenance meets the technical requirements

The main factor is the use of installation and adjustment , use and maintenance  repair and other maintenance meets the technical requirements. According gimbal tapered roller bearing  installation , use, maintenance, maintenance of technical requirements for the operation of the bearings to withstand load, speed , temperature , vibration, noise and lubrication condition monitoring and inspection , abnormal immediately tapered bearing supplier find reasons to adjust to return to normal. Without further need for impact resistance as spherical roller thrust bearing materials using chrome steel , chrome molybdenum steel , nickel-chromium -molybdenum steel , the use of carbon infiltration quenching the steel from the surface to the proper depth of a hardened layer . 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.

Roller Bearing avoid resonance with the host ,

to control noise  bearings must take countermeasures root causes for these noise generation , in order to receive a permanent cure results. The main route is :(1) Choose low noise Cylindrical roller bearings ;  (2) avoid resonance with the host , avoiding sensitive resonance speed ; (3) from the cylindrical roller bearing applications link on trying to eliminate noise ;  (4) is invalid in other ways , additional measures of noise and silencer .  bearings when the temperature rises , first determine whether china bearings the malfunction, as indeed increased, should be treated as follows :  check the cooling water pressure , flow and piping systems are normal. If water filter may be clogged down and can not handle , you can stop treatment, when it is confirmed to work , and then put into use.  Should check governor oil pressure, oil pressure may result if the cooling water hydraulic valves closed.  Check whether there is abnormal sound bearings , cylindrical roller bearings and high precision bearing detect whether there are abnormal swing . Take oil samples to observe whether there are changes in oil color , and conduct tests to see whether the deterioration. If confirmed deterioration , should be shut down to replace with new oil.  Check the oil standard oil level is normal, if abnormal , check the tank drain valve is closed. If closed, should fill the oil , if it is sealed cushion oil leakage should stop processing
