Mini waterproof cooling fan manufacturer tell you car radiator cooling fan of bearing system is of great importance

Tong chi micro waterproof automotive cooling fan manufacturer advice in selecting a cooling fan of bearing system is the best ball bearing, why tong chi micro motor cooling fan manufacturer do you say so? Because the life of the automobile cooling fans usually depends on the reliability of the bearing and ball bearing system has proved has the characteristics of high efficiency and low heating.


tong chi micro motor cooling fan manufacturer told you ball bearing rolling friction, by metal bead rolling, contact surface is small, small friction coefficient; And oil bearing for sliding friction, contact area is large, use for a long time, after oil volatilization, bearing is easy to wear and friction coefficient is big, the noise caused by the late life is short.


tong chi micro motor cooling fan manufacturer think a fan with good quality in addition to the large air quantity, high wind pressure, the reliability is also very important, the bearing in the form of a cooling fan used this is very important.


tong chi micro motor cooling fan manufacturer know high-speed fan shall use ball bearing ( 球轴承) While low speed fan using cheap oil bearing ( 套
轴承) 。 Use only one bearing oil bearing fan; And Ball bearing fan will need two bearings, Ball bearings, is the '1 + 1
Ball Sleeve', still with the composition of the oil bearing. More advanced than single ball is double ball bearing, namely Two
the Balls. Oil bearing life in general is 10000 hours, single ball bearing for 30000 hours, the double ball bearing for 50000 hours or more ( The environment temperature setting below 25 ℃) 。


tong chi cooling fan manufacturer to tell you the fan of micro and subcompact cars use oil bearing made of copper base powder sintering, use oily add lubricating oil to reduce the number of sliding friction bearing and lubricating oil by lithium grease and oil special modulation. Tong chi micro motor cooling fan manufacturer know as the long time operation, within the bearing oil will evaporate and dry, the friction coefficient increases, fan operation affected, may appear different sound, speed slow don't even turn phenomenon. And ball bearing replaced by rolling friction for sliding friction, low friction coefficient and overcomes the drawback of the coefficient of friction can become, and running stability is strong, relatively is much longer service life.
