subject: The Materials And Standard Of Fag Rolling Bearings [print this page] Materials with the FAG rolling bearings The perform efficiency from the FAG rolling bearings depends to some fantastic extent within the substance qualities. FAG generally uses the lower alloy and total quenching chrome of higher purity since the components to manufacture bearing collar and rolling. As to the bearings which are ready to endure the load of large effect and alternative bending anxiety, AFG adopts carburizing steels.
Besides, there are NSK bearings, SKF bearings, timken bearings. In recent yrs, due to the increasing enhancement in the top quality metal of bearing, FAG has the capacity to enhance the bearing capability. Study final results and functional experiences confirm which the latest standardized steel rolling bearing can own infinite exhaustion power if it's not significantly feasible for that bearing to own good lubrication, the environment cleanness and load.During warmth processing, the FAG bearing collar and Cylindrical roller bearing human body make certain bearing in a hundred and fifty degrees. The size is stable. For increased functioning temperature, it demands special warmth therapy method.If bearing is utilized in corrosive surroundings, it requirements the bearing metal to get corrosion resistance. FAG standardized bearings which might be built of stainless-steel have S inside the code prefix and W203B in code suffix. The bearing and the whole quenching metal bearing have commonness in the main dimensions and carrying capacity. In order to keep its corrosion resistance, its surface cannot be damaged in the process of installation and use.FAG si3n4 ball is utilized in ceramic spindle bearing. The ceramic ball is lighter than steel ball and the centrifugal force and friction are also drastically less than small ball. This bearing can still achieve fairly substantial speed in grease lubrication. In addition, it has a long service life and reduced temperature.Evaluation standard of high-speed adaptability with the FAG bearingsGenerally, the best allowable speed in the rolling bearing depends on its highest allowable functioning temperature. The working temperature depends about the heat that is created by the bearings, transmitted to the bearings and given off by the bearings when the friction bearings function. The temperature decides the rotation speed. What's more, the factors that are affected by the rotation speed include the bearing type, size, precision, bearing peripheral parts, clearance, keep frame structure, lubrication and load.Limit speedThe factor that decides the limit rotational speed is the mechanical limit, namely, the bearing parts' power or the sliding speed of contact seal. Within the FAG bearing functionality tablet, there's limit speed and unlimited reference speed by standards, namely, the bearing rotation limit to contact seal.
