What are the characteristics of 6307 / HR22T2 bearing manufacturer

6307 / HR22T2 bearing factory what are the characteristics of source: bearing | last updated: - 2020 06 - 11 6307 / HR22T2 bearing factory what are the characteristics of motor bearing running noise slightly at work because of what? 1. Bearing temperature is too high, when the agency is running the installation of bearing parts allowed to have a certain temperature, when the hand touch body shell, should not feel hot as normal, conversely indicates that bearing temperature is too high. The cause of the high bearing temperature are: lubricating oil quality does not conform to the requirements or metamorphism, lubricating oil viscosity is too high; The assemble tight ( Inadequate clearance) ； Bearing assembly too tight; Bearing race in internal rotation shaft or housing; Too much load; Bearing cage or rolling body fracture, etc. 2. Bearing noise slightly at work is allowed in the operation of motor bearing noise, if you have any abnormal noise or excessive noise or sound, suggests that the bearing failure. Cause noise of rolling bearings is more complex, one is the bearing inner and outer surface wear. Due to the wear and tear, damage to the bearings and shell, bearing and shaft cooperate relationship, lead to axis deviation from the correct position, when axis at high speed movement produces sound. When the bearing fatigue, its surface metal flake, also can produce sound make bearing radial clearance increases. In addition, the bearing lubrication, forms the dry friction, and bearing broken etc all make abnormal noise. Bearing wear loose after kuang, maintains a looseness damage, also can produce sound bearing damage bearing hardness is what? Bearing hardness is how much? Many customers ask, what is the hardness of bearing? Bearing hardness is how much? Professionals to explain in detail: the so-called bearing hardness also is one of the detection measure of bearing, the bearing production line, every process is very important, bearing of the each step in the process of production is very important. Hardness is one of the important means of Lin, rolling bearing and contact fatigue strength, wear-resisting, the relationship between the elastic limit is first closely, since the joint affects the dynamic bearing right sweet, soft he usually according to the degree of the Yin style and size, axial load bearing size and wall thickness of the overall situation to decide. The deep groove ball inside and outside the ring and ball using high chrome steel GCr15 or GCr15SiMn two kinds of bearing steel manufacturing ( High chromium steel, usually say that the bearing steel) 。 Bearing ring in the rockwell hardness of HRC60 - 65; But usually states at 62 degrees, is too high, bearing too brittle, bearing is easy to bad. Bearing steel ball in rockwell hardness HRC60 - 66. Made of GCr15 bearing steel ball hardness in rockwell HRC62 - Within the scope of 66; GCr15SiMn made in bearing steel roller in the rockwell hardness of HRC60 - 64, steel ball in rockwell HRC60 - 66 range. Usually only rockwell hardness 50 - bearing 55 degrees, hardness is low, not suitable for high strength work. Focus on good bearing is also a very important part of hardness, if bearing hardness is low, will cause bearing prevails, or wear a few pieces ahead of time, bearing hardness is higher, of course, is detrimental to the bearing inner ring fracture.
