To identify the quality of the stainless steel bearing

Five recruit to identify quality stainless steel high temperature bearing 1, see material pledge, stainless steel bearing high temperature impact of stainless steel can be from their developing view, on the hardness and precision of the two aspects of good stainless steel high temperature bearing than use inferior stainless steel high temperature bearing to be a lot higher. 2, we can observe through high temperature stainless steel bearing the naked eye, from internal and external track, see whether it is a circular arc wall, no peeling, signs of peeling and whether there is a crack phenomenon such as rolling the appearance, the whole framework whether there is lax, etc. 3, out of touch for identification, common enterprise normal stainless steel high temperature influence inside and outside the circle and the clearance between the rolling element bearing general won't produce too big, we teachers hand swinging to inner race to stop, see whether it can have obvious shake, if have, so they just use inferior high temperature stainless steel bearing. 4. Stop stainless steel high temperature bearing rotation, if in the process of turning insensitive and have cut off feeling, or have shake when rotating at high temperature stainless steel bearings, also is inferior stainless steel high temperature bearing. 5, the price of this work, we have always believed in a word, truth, and a penny can't showed, let me lose more, if high temperature stainless steel bearing cost much less than normal market price, so, you have to be careful, this is likely to be shoddy, because the cost of stainless steel high temperature bearing itself is relatively high, if the price is too low, even the basic cost is impossible to achieve, how could really is high quality stainless steel high temperature bearing. The previous: bearing release material surface strengthening technology classification next up: none
