NTN cylindrical roller bearing used matters needing attention for life

NTN bearing is precision components, need to be careful when using. No matter how high performance using cylindrical roller bearing, if use undeserved, will not be able to get the desired performance. Here are some bearing the use of the matters needing attention. A, maintain the cleanness of bearing and its around environment even invisible to the naked eye fine dust into the NTN bearing, also will increase the wear of bearings, vibration and noise. Cylindrical roller bearings and its surrounding accessories should be kept clean, especially the dust and dirt, tools and work environment must be clean. Second, the use is not allowed to be careful when installation powerful punch, are not allowed to be directly with hammer percussion bearing, are not allowed to be passed on roller pressure. Three, use appropriate and correct installation tools as far as possible use of special tools, such as special heater and the drawing of machine tools, etc. , to avoid the use of cloth and short fiber, things like that. Four, to prevent rusting of the bearings directly take bearing with the hand, must wash hands sweat, and again after coated with high quality mineral oils, especially in the rainy season and summer to pay attention to rust. However, in some special operating conditions, cylindrical roller bearing can get more than the life of the traditional computing, especially in the case of light load. These special operation premise is, when the rolling surface ( Track and rolling piece) Can be separated by a lubricating oil film effectively and the surface of the limit of pollutants may cause damage. In fact, on the premise of the ideal, the so-called permanent bearing life is possible. There are many factors that can affect the NTN bearing service life, can be roughly divided into use factors and internal factors. Use factors mainly refers to install, use, maintenance, maintenance, repair and so on meets the technical requirements. Installation conditions is to use one of the primary factor of factors, caused by improper installation of a complete set of cylindrical roller bearing stress changes between various parts, NTN bearing at the end of the abnormal state of operation and early life. Internal factors mainly refers to the structure design, manufacturing process and material quality and so on three major factors in determining the quality of bearing. Bearing manufacturing generally go through multi-channel processing process. The rationality of the processing technology, advanced, stability will also affect the service life of bearing. Which affects the quality of the finished cylindrical roller bearing, heat treatment and grinding process has more direct relation with NTN bearing failure.
