Miniature bearing failure reason analysis

Miniature bearing refers to metric series, outside diameter is less than 9 mm; Inch series, outer diameter less than 9. All kinds of bearing 525 mm! Main material is carbon steel, bearing steel, stainless steel, plastic, ceramic, etc. , including minimum inner diameter can be 0. 6 mm, inner diameter of 1 mm more commonly. Miniature bearing is suitable for all kinds of industrial equipment, small rotary motor of high speed low noise field, such as: office equipment, micro motor, instrument, laser engraving, small clock, soft drive, pressure rotor, dental drill, drive motor, stepping motor, VCR magnetic drum, toy models, computer cooling fan, paper, fax machine, and so on related areas. About 40% in miniature bearing failure is by dust, dirt and debris contamination and corrosion. Pollution is usually not correct use and the use of bad environment, it can also cause torque and noise problem. By the environment and pollution produced by the miniature bearing failure can be prevented, and through simple macroscopic observation is can determine the causes of such failure. As long as reasonable use and install, the miniature bearing is easy to avoid erosion. Denudation is characterized by in the path of the miniature bearing ring rolling have produced by impact load or incorrect installation of indentation. Denudation is usually happened when load exceed the material yield limit. If the installation is not correct to make a load across the miniature bearing ring also can produce denudation. Miniature bearing ring on pit will produce noise, vibration and the additional torque. Seiko bearing, the total investment of more than 1700, selected mature production equipment, strict production process management, main mute MR bearing and deep groove ball bearing series, the production of bearings, smooth rotation, low noise, small gaps, and the advantages of long service life, stable quality, the monthly production capacity is 600 - 8 million sets, if you want to buy miniature bearing, national sales hotline:
