NSK bearings of high temperature damage in the using process of matters

NSK bearings in addition to the quality, also belong to the very precision parts, is not only the bearing high function, if the use of inappropriate and in the process of using not only cannot achieve the expected function effect, and make the bearing damage very easily, once sure everyone pay attention to in terms of lubrication. In general in the high temperature bearing in the bearing quality is very strong, not general bearing products can match, but there are good and bad, even bearing such as authentic Japanese production of bearing is bearing quality is much better than the domestic joint venture production, so how can we get to detect NSK bearing quality! A cage is better than two body while the new process using one cage, but it is just to save material, and performance than the difference between the two bodies such as the rotary. In general, the service life of bearing has relationship with three factors, one is the quality of the bearing itself. The second is using the environment. Three is to install method. Chamfering is shining bearing chamfer does not decide the quality of the bearing, but it reflects the bearing processing method. Chamfering is black, the heat treatment such as quenching, so increase the hardness of bearing, and some people think the chamfering is black not good-looking is not process completely, this is a myth. By surface feeling bearing quality according to the sales experience found many clients said that as long as the quality of bearing surface brightness is good, this is wrong. Light should be on the surface of the bearing is a kind of raven, of the cause of the raven is used in high temperature bearing steel is up to standard and its cutting fluid used in the grinding process and etc, produced by the two before. Even the smiling face of dust into the bearing, invisible to the naked eye can also add bearing wear, vibration and noise. Directly take NSK bearings, with the hand to wash hands sweat, robust and coated with high quality mineral oil and then suspend operation, special in the rainy season and summer to pay more attention to rust. So bearing damage to want how to deal with. If the correct use of bearings, can be used to achieve fatigue life. But there will be unexpected injury prematurely, no ability to use. This early damage, and fatigue life, it is called the fault or the quality using the limit of the accident. Much due to the installation, use, do not pay attention on the lubrication, intrusion of foreign bodies from outside, to the shaft, shell heat affected study enough. About bearing damage status, such as: roller bearing ring, guard card injury, as a reason to consider, lack of lubricant, not suitable for, for the defect of oil discharge structure, the invasion of the foreign body, bearing installation error, the deflection of the shaft is too large, also can have these reasons. Therefore, only investigate bearing damage, the real reason is hard to come by injury. But, if you know the use of NSK bearings machinery, conditions of use, high temperature surrounding the bearing structure, to understand before and after the accident, combined with several damage status and causes of bearing, can prevent the similar accident happen again. After introduction can be found, correct use will not cause damage to the bearing, the installation is not correct, use external immersed in foreign bodies, and improper lubrication is the main reason for the high temperature bearing damage, so that enterprises in the use of the bearing should be pay more attention to these aspects, to prevent the occurrence of damage, bearing impact work.
