Rolling import bearing common trouble generally has two kinds: one is bearing installed parts temperature is too high, and the second is in the running bearings have noise. Today we will analyze the two reasons of these faults, and help everybody in the use of bearing more convenient.

First, rolling bearing the temperature is too high

In the machine mechanical operation, installation import bearing parts are allowed to have a certain temperature, when the hand over institutions shell, should not feel hot as normal, and indicates that bearing temperature was too high. Scroll to high temperature import bearings of reasons:

1, lubricating oil quality requirements or to deteriorate, high viscosity lubricating oil;

2, mechanical assembly close (clearance deficiency);

3, bearing assembly too tightly;

4, the circle in the bearing shaft or shell and rotation;

5, overload;

6, bearing maintains a or rolling body break.

Second, rolling import bearing noise

Import bearings rolling in the work to allow a slight operation noise, if too abnormal noise or noise or knocking, indicates that the bearing is a failure. The rolling bearing produce noise reason is more complex, analysis the main for the following reasons:

1, bearing with inner and outer surface wear,. This kind of wear destroyed bearing and shell, bearing and the shaft with relations, lead to axis deviated from the correct position, in the shaft in high-speed motion produce abnormal sound;

2, when bearing fatigue, the metal surface spalling, also can make the bearing radial clearance increase produce abnormal sound;

3, bearing insufficient lubrication, form of dry friction,  will be broken cause abnormal sound;

 
4, bearing wear loose , retainer a looseness damage, also can produce different noise.
