A bearing mounting and dismounting must be cautious

Different types of thin-wall deep groove ball bearings of different sizes, installation methods and tools are not the same, including mechanical or hydraulic. Here to explain some common basic installation methods and precautions.

First, do not hard balls installed, this will lead to the ball and the contact surface local overload, leading to premature bearing failure.
Second, do not use hard tools such as a hammer, screwdriver like beating bearing surface, which would allow the bearing outer ring fracture or embrittlement.

Second, the cleaning of the bearing

The use of a clean environment for the bearing is very important. The surface roughness of thin-wall deep groove ball bearing ring rotating surface and rolling element accuracy is about 1/10 μm, such a smooth ball surface contaminated, its impact is very serious. Between the rolling surfaces of the lubricating layer is generally 0.2 ~ 1 μm, the particle type impurity is greater than the lubricant particle diameter will be the excessive rolling elements rolling and the aligning roller bearing steel to produce localized pressure, and ultimately will lead to permanent material fatigue. In addition to this, the external environment of the dust particle size of up to 10 μm, also reversed Spherical Roller Bearing damage. Because of the clean work environment for bearing how important ah.

Third, the process of the bearing detection

Through in the process of using heat to dry up the induction bearing temperature If the temperature exceeds the limits will automatically alarm to prevent burning shaft happening. High temperatures often said that bearing in an abnormal situation. The high temperature is also harmful to the bearing lubricant. Sometimes thin wall deep groove ball bearings overheating can be attributed to the bearing lubricant. If the bearing in the long term even transfer over 125 ℃ temperature reduce bearing life. Caused by high temperature bearings including: insufficient bearing lubrication lubricant unqualified, which contains impurities, the load is too large it may be bearing internal clearance is not enough oil seal friction.
