SKF bearings in the middle of running, the noise is unavoidable. But bearings a variety of problems with different noise response. Today we are going to talk about is the bearings in the event of more serious problems, SKF bearings sound which is it?: can we stop these noise?
　　SKF bearings in the event of serious injury, usually issued two voices: sharp sounds and fall rolling sound. For both of these voices, and what characteristics do?
　　First, let us look at sharp song what features does?
　　It is metal sliding friction angle calls have quite severe, although bearings temperature rise is not high, on bearings life and grease life without much impact, nor does it affect the rotation, but not pleasant sound disturbing, particularly large short cylindrical roller bearings radial load makes this noise.
　　Its characteristics are:
　　A. bearings radial clearance of large easy to produce.
　　B. usually appears in the grease lubrication, oil lubrication is more rare.
　　C. with increasing bearings size reduces, and often appear within a speed range.
　　D. Winter often, it appears there is no rules, and unpredictable, performance, installation, operation and filling grease amount and conditions.
　　SKF bearings solutions for each type of noise has a relative. Tip song was no exception. This noise can be reduced radial clearance of bearings and the use of outer ring raceway of shallow structures to prevent. If you still cannot solve the problem of noise, it should replace the bearings or look, if other problems causing the bearings noise.
