Analysis of bearing hard through low phenomenon

Analysis of bearing hard through low phenomenon in bearing processing, the problem is the most easy to produce, make the bearing heat and low hardness. Because it will cause the waste of energy, bearing products also affects the overall processing progress, so its causes must be careful analysis, engineers today and everyone to share together. 1, raw material quality problem. This is not only reduce the hardness is important influence factors of bearing products, is also one of the important reasons caused the early failure of bearing products. When choosing the bearing material, its hardness is called for, once do not conform to the standard, should be banned. 2, bearing in the process of tempering, the quenching process, and inadequate due to temperature, will make the workpiece hardness decreased. According to the integrity of the quenching process, can know, the factors that affect the bearing in the heat treatment quenching mainly includes: one is the heating temperature is not up to standard; Second is the insufficient cooling rate; Three is the time when the quenching cooling is insufficient, once appear insufficient cooling time, again carries on the tempering, will cause hard through low; Four is the effect of tempering process, mainly including heat preservation temperature, time, equipment, etc. Above if have not understand can online consulting professional service engineers: Lu Tianze - 0769 22987612 13827223590 recommended reading: 【 Imported bearing specification 】
