Roller Bearing in the dust and other foreign matter
If the rolling bearings appearance of cracks , dents or corrosion , such as a rivet that will attack the periodic noise and vibration , the period can be fixed with a constant rotational speed but most necessary correspondence between the channel will continue scars attack, scars on hidden when on the ball , and this noise with the device and the premise is necessarily smooth transition .
Such noise control methods are: when the device is not a knock bearings, cylindrical roller bearing and the shaft assembly before loading ramp when loading to avoid bearing housings ; avoid shock and vibration during transportation to avoid bearing corrosion inventory ; using viscosity smooth high fat .
bearings in the dust and other foreign matter , would attack the so-called non-periodic vibrations and dust, sound, vibration and noise of the size of its uncertainty, and with or without .
Dust sound control methods are: to improve the cleaning methods bearings , before the device will cylindrical roller bearings , shaft, housing bore and match parts clean and fully severely Qing Shen ; eliminate foreign objects inside the smooth agent ; improve Bearing seals ; prevent the use of information impure or foreign body embedded plastic stick rack .
lubrication caused by the elements and Countermeasures
Lubricant selection errors, lack of lubricant aging or the onset of induration , lysn roller bearing can lead to the occurrence of vibration and noise , and this noise is not necessarily the rule. About this situation, as long as the selection of the appropriate smoothing agent to adjust its smooth dose , extended use of life smooth and reasonably determine the change agent cycle .
The impact of vibration on the tapered rollers failure of the bearing INA bearing obvious example : peeling , indentation, corrosion, cracks, wear , etc. will be reflected in the bearing vibration detection , so by using a special rolling bearing vibration measuring devices ( frequency analyzer and vibration analyzer etc. ) to measure the size of the vibration , the specific circumstances of abnormal vibration frequency distribution can be inferred by the measured value conditions due to cylindrical roller bearings or sensor installation location is different , and therefore requires prior measurement of each machine after analyzing and comparing the value determined criteria .
With INA bearing temperature usually run slowly increased from 1 to 2 hours after reaching steady state. Machine at normal temperature due to heat the bearing capacity , heat capacity , and different speed and load , if lubrication, improper installation , the cylindrical roller Bearing abrupt temperature rise , there will be abnormally high , then you must stop and take the necessary precautions.

tapered roller bearing requires a fixed position in three directions radial
Ntn bearing in use to give a strong impact , will have scars and indentations, become cause of the accident . Severe cases, crack, fracture, it must be noted .
Avoid ntn bearings with lysn roller bearing existing workers instead must use the right tools . We have always stressed the importance of the tool , because there are too many customers are using the wrong tool in the installation resulting in a spherical roller bearing damage.
The shaft and bearing , the bearing requires a fixed position in three directions radial, axial and lysn tapered bearings tangential direction . Radial and tangential positioning through the tight fit of the bearing rings achieve mining , axial positioning only in a few cases a tight fit ; generally limit the use of axial parts , such as the cap and ring, etc. will limit the axial position in the clearance range.
Should be selected with the focus on the following four points:
( 1 ) of the bearing rings and the circumferential surface should be well supported even by force , in order to reduce distortion , and give full play to the carrying capacity spherical roller bearings .
( 2 ) rings in its tangential direction with not slide surface , otherwise it will damage the mating surfaces .
( 3 ) the free end of the bearing must be able to change the length of the shaft and housing bore fit , which must have the ability to adapt to the axial position within a certain range of swimming .

paired tapered bearing therefore necessary to monitor the oil change.
Fundamental types of drum-type roller bearings either using window glass fiber reinforced polyamide (nylon) 66 stick frame (suffix T), also can be machined solid brass stick rack (suffix MB). Glass fiber reinforced polyamide 66 insist on lower shelf stable split roller bearing up to temperatures form 120 ℃. If the bearing oil is smooth, then smooth oil additive will reduce the use of stick frame life of aging oil at low temperatures also have an adverse effect on the stick rack; therefore tapered bearing manufacturer necessary to monitor the oil change.
Drum Roller Bearings heat treatment
After heat treatment of the FAG drum roller bearings, tasks temperatures up to 150 ℃, the temperature of the outside diameter of 120mm beyond the task of bearing up to 200 ℃, the size is still able to adhere firmly. If the bearing polyamide stick frame, the frame data necessary to pay attention to adhere to temperature constraints.

Bearings sales center edit
Bearings sales center edit , fall season, City ushered in the annual autumn festival investment and trade as one bearings for printing machine of the investment section of activities , Municipal Government on September 20 afternoon foreign investment in Hotel honor winner of the award ceremony. again won the " Best Foreign -invested enterprises in " title .
In this review , the again was named " Best Foreign -invested enterprises in City " title , China chief representative of the temple mound receive the award. Ltd. for its remarkable ability to promote economic development , and products with high technological content and many china bearings other advantages , has been highly praised by the municipal government , has been selected as the 2009 Best Foreign -invested enterprises in City , China's total as a representative of the temple mound , general manager of the enterprise received a municipal award .
in Japan since 1916, first began production of bearings , bearing a Japanese pioneer in the development and provision of various types of bearings for the development and progress of machinery industry has made a great contribution. Now , bearing areas , ranking first in Japan , but also in the forefront in the world . through a global network of mutually reinforcing efforts to promote development capabilities , production capacity, sales ability and business management capabilities , and strive for greater progress.distributor in China , according to reports, this is the Kunshan NSK company following the 2006 , 2007 , 08 years later, this is the fourth consecutive year "Best Foreign Investment Enterprise" award this honor .

often accompanied by fatigue cracks
Contact fatigue spalling occurs in INA bearing surface , often accompanied by fatigue cracks , first produced from the contact surface of the following maximum alternating shear stress , and then extended to the formation of different surface flaking shapes, such as point-like pitting or pitting as spalling , flaking into small pieces called superficial peeling. Due to the gradual expansion of flaking surfaces , but often extend to the deep , forming deep peeling. Deep contact fatigue double row cylindrical roller bearing spalling is a source of fatigue failure .
Continuous wear will cause spherical roller thrust bearing parts gradually damage and eventually lead to the loss of dimensional accuracy INA bearings and other related issues . Wear may affect the shape change , with the gap increasing and work surface morphology changes that may affect the lubricant or it reaches a certain level of pollution caused complete loss of lubrication , which makes bearings and even the loss of rotational accuracy can not operate normally . Wear failure is one of the kinds of bearings common failure mode, press the wear is usually divided into the most common form of abrasive wear and adhesive wear .
