6307 / HR22T2 bearing factory source advantage is introduced: bearing | last updated: - 2020 06 - 14, 6307 / HR22T2 bearing manufacturer advantage of bearing what is hardness? 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. On low noise bearing installation and adjustment of right way bearing noise is inevitable, so many have chosen when check the bearing the use of low noise bearings, that of low noise bearings bearing used in the installation and adjustment of peace is the same? The author here to share about low noise bearing the correct way of installation and adjustment. 1, installation and adjustment of low noise bearing can also emulate grouping method of long life bearings, makes the interference fit the size is consistent, bearing clearance is relatively consistent, and hope to cooperate with interference within may take smaller values, to ensure the deformation of bearing raceway is small, and rolling body caused by noise. 2, clearance on the relationship between the noise is very large, ideally when import deep groove ball bearing is in running state, the highest temperature clearance value is zero. Judging methods of clearance is too large, stationary state that the axial displacement of the reciprocating amplitude is bigger, the big and heavy turbidity of a noise during operation. 3, if the hate sharp whistlers, shows bearing preload is too big, preloaded, bearing a large prestressing degree should have to relax. If the clearance is too large, can make the two bearing ring along the axial relative offset slightly: both reduced clearance, and increase the axial rigidity, bearing noise can be reduced. 4, rolling body around would not bite into the no-load area or channeling, that will not only increase the noise can also cause wear and tear, and the small clearance and large axial stiffness can eliminate the phenomenon. But cannot too small clearance, lest cause high temperature and shorten the life. 5, sometimes due to host large working temperature range, or shaft with a hole the size of the discreteness is very big, can't get a setting on a proper clearance, in this case, can be used for bearing outer ring elastic constant pressure preload method.
