inner and outer rings, rolling a strip of any one there.

c. raceway, ribs, rolling a significant injury card.
d. confrontation frame badly worn or loose rivets ferocious.
e. raceway, rolling rust and have scars.
f. rolling surface, rolling on and playing a significant indentation marks.
g. inner diameter surface or outer diameter on the creep.
h. overheating discoloration ferocious.
i. grease seals and dust sealed bearings to severe damage.
Nsk Backing bearings in use, sometimes we can hear bearing noise, in fact, theoretically, the bearing itself does not produce noise, and the noise we heard was bearing directly or indirectly arising from the surrounding structure vibrating sound effect. So, why would the bearing vibration it? Today, it is for me to explain something simple for everyone, please read carefully!
When changes in the number of rolling loads, will produce excitation when a radial load on a load of imported backing bearings  its load bearing rolling element number will be some changes in the operation, which caused the load shift direction . The resulting vibration is inevitable, however, now seems to have a bearing vibration and noise are reduced, which is why? Nsk bearings due to the current use of the design to reduce the pre-load, rolling load at all, thereby reducing vibration, but also reduces the noise. Although the use of the pre-loaded, but can not completely relieve the vibration and noise problems. So, how to further reduce the noise it?
1, to prevent resonance excitation components and between the components of the vibration excitation.
2, change the stiffness, and to achieve the purpose of changing the critical frequency.
3, remove the critical excitation vibration.

nteract with senior engineers to understand the global leader in bearing technology

Shanghai Jiaotong University Li-Feng Xi dean renew Timken Scholarship , said: " Thank you very much Timken Company continues to provide scholarships to support my school education development and personnel training , while also hoping Timken Company in the field of mechanical engineering experience and technical advantages , together for the training of the younger generation of innovative engineering talents and efforts . "
Back in 2006 , Timken Company and the Shanghai Jiaotong University jointly established the " Shanghai Jiaotong University Timken Scholarship" , winning students not only get grant funds , as well as the opportunity to visit Timken Timken bearings located in Wuxi engineering training center, interact with senior engineers to understand the global leader in Tapered bearing technology . Timken also established with China Timken other prestigious scholarships to train in different fields of engineering and technical personnel.
TIMKEN Timken join Shanghai Jiaotong University scholarship renewed in order to continue to accelerate the pace of development in China , helping China 's top backing bearings schools to train more outstanding graduates to build a solid professional knowledge , with a first-class team of engineers innovative thinking . Ethics and Integrity is Timken 110 years of development history in one of the core values ​​advocated , but also the spirit of relentless innovation Timken Bearing Company is proud heritage.
