What are the performance of the steel wire race bearing requirements? Wire race bearing performance

Steel wire steel runway bearing raceway bearing is also called. It relies on the load characteristics of higher precision, better performance, such as higher has been widely used in many fields, but do not know much about friends still don't know how to choose a wire rolling bearing, don't know what are the performance requirements of the steel wire race bearing, today the author is to introduce the performance requirements of the steel wire race bearing, hope to be of help. One, the steel wire race bearing performance demands 1, hardness hardness is one of the important quality of bearing quality, to contact fatigue strength, wear resistance, elastic limit has a direct impact. The hardness of bearing used in the state of general to achieve HRC61 ~ 65, bearing can get high contact fatigue strength and wear resistance. 2, antirust performance requirements in order to prevent bearing parts and finished products during processing, storage and use of corrosion rust, bearing should have good rust resistance. 3, self-aligning performance requirements relative bearing shaft centerline hole centerline, bearing can still work normally. Rolling bearing working speed should be lower than the limit speed. Using high precision bearing, improving the structure of the cage and material, using oil mist lubrication, cooling conditions, etc. , can improve the speed limit. 4, lubrication performance of bearing lubrication has reduce bearing internal friction and wear, prevent burning stick; Prolong the service life; Discharge frictional heat, cooling, prevent hotbox, prevent the aging oil; Also has to prevent foreign matter into the bearing internal, or to prevent rust and corrosion. 5, wear-resisting performance requirements bearing work, not only between race, rolling element and cage rolling friction, and sliding friction will occur, so that the bearing parts wear continuously. To reduce the number of bearing parts wear, keep bearing accuracy stability, prolong the service life, bearing should have good wear resistance. 6, contact fatigue performance requirements bearings under the action of cyclic load, the contact surface is easy to fatigue failure, namely appear cracked spalling, this is the main bearing damage forms. Therefore, in order to improve the service life of the bearing, bearing must have very high contact fatigue strength. 7, processing performance requirements bearing parts in the process of production, to go through many cold and hot working process, in order to meet the requirements of mass, high efficiency, high quality, bearing should have good processing performance. For example, the cold and hot forming properties, machinability, hardenability, etc. Second, the steel wire race bearing USES steel wire race bearing implements tight fit of ball and raceway, load increase, better performance, better precision and is more suitable for different purposes; Wire race bearing mainly depending on the contact Angle can be divided into 45 ° to 30 ° or four-point contact ball bearing, suitable high speed and high precision bearing the double column tilt, low speed, good operation, flexible contact ball bearings and three in the stiffness and tightness good wire roller bearing four kinds of structure forms, is divided into seven series products, widely used in machinery manufacturing, medical equipment, textile machinery, food and packaging industry, the purpose of the steel ball and raceway on the basis of general bearing some and higher requirements, it can be in clean, high temperature and vacuum environment, this is some of the bearing cannot reach. Three, wire race bearing selection technique 1, determine the bearing type. Bearing model is commonly used by the user's technical personnel according to the product of form a complete set of conditions and the load bearing for selection. 2, determine the bearing clearance. User when buying bearings generally just let us know in what type, grade, rarely on bearing clearance request, business people must ask bearing conditions of use, which the bearing rotating speed, temperature, tolerance is directly related to the selection of the bearing clearance. 3, choice of oils and fats. The choice of grease are generally according to the requirements of the bearing rotating speed, heat resistance, noise and choose starting torque, etc, requires us to detailed understanding of the basic conditions of all kinds of oils and fats, make a right choice. 4, determine the occupied space. Usually want to make sure of the size of the bearing, and then according to the size to choose rolling bearing. 5, considering bearing rigidity. Bearing rigidity is refers to the size of bearing force required for the production of unit deformation, generally on some machine tool bearings, rigidity is a more important consideration. Above is the author summarize for you what are the performance requirements of the steel wire race bearing, wire race bearing performance requirements, the entire content of the application and selection skills, you can see is the performance of the steel wire race bearing requirements have hardness requirements, antirust performance requirements, self-aligning performance requirements, lubrication performance requirements, wear-resisting performance requirements, contact fatigue strength requirements, processing performance requirements, etc. , you can notice when the choice, choose the more appropriate wire rolling bearing. In addition, if you have wire race bearing about the other questions can telephone contact us at any time of jiaxing bearing co. , LTD. , we will provide you with a more professional solutions. Article the difference between the steel wire race bearing and general bearing, labels and use what the performance of the steel wire race bearing requirements
