The importance of IKO ball screw bearing sealing

Bearing seal is keep good lubrication condition in order to make the IKO bearings and normal working environment, give full play to the performance of the bearing, prolong service life, the rolling bearing must have appropriate sealing, in order to prevent the leakage of lubricants and the invasion of the dust, moisture or other contaminants. Ball screw bearing seal can be divided into two categories, own seal and seal. The so-called bearing with seal is made bearing itself into a sealing device. Such as bearing belt, etc. This seal take up the space is small, easy installation and disassembly, cost is low. Alleged bearing and sealing device, it is inside the installation end cover manufacturing into a sealing device has a variety of performance. Choice of IKO bearings and seals should consider the following several major factors: bearing lubricant and types ( And) ; The size of the bearing work environment, take up the space; Shaft supporting structure advantages, allowing the angular deviation; The circumference of the sealing surface speed; The working temperature of bearing; The manufacturing cost. Thickener is also related to oil, water grease thickener determines the resistance of the water. In principle, oil do not mix different brands, even if thickener, grease is also due to the different additives affect each other. Painted the bearing with anti-rust oil, must be clean petrol or kerosene cleaning carefully, and then use a clean, high quality or high speed high temperature grease before installation. Closed bearing not clean fuel. IKO bearings in the installation, if not carefully adjusted, adjust bearing pain, may lead to more friction and vibration. These could accelerate fatigue, reduce ball screw bearing and so on mechanical parts may damage the life of a life. In addition, the increased vibration and friction can greatly increase the energy consumption and the risk of premature failure. In use process, often IKO bearing basic monitoring of external operation, such as temperature, vibration and noise measurement conditions, and so on. Potential problem these regular examination, early detection, prevent the machine from accidental suspended, hence leading to the implementation of production plan, improve productivity and efficiency of the factory. In the process of operation, need the right bearing lubrication, to improve its performance. The ball screw bearing lubrication method, divide the grease lubrication and oil lubrication. In order to play a good IKO bearing function, first of all, to choose the right condition, for the purpose of the lubrication method is used. If only considering the lubrication and oil lubrication dominant. However, can simplify the structure of bearing around the professional knowledge of grease. According to the bearing working condition and working environment requirement for sealing on the engineering design is often integrated use of various seal form, in order to achieve better sealing effect. IKO bearing rotating at high speed, especially the speed close to or exceeds the limit speed of the dimension table records, should pay attention to the following main items: ( 1) Use the precision bearing; ( 2) Analysis of ball screw bearing internal clearance ( Considering the temperature rise of bearing internal clearance reduction) ; ( 3) Analysis of the cage material type ( For high-speed rotation, suitable for use of copper alloy cage or phenolic resin system. But there are also suitable for high speed spinning of synthetic resin molding cage) ; ( 4) Analysis of lubrication methods ( Lubrication is suitable for high speed rotating cycle, splash lubrication, and lubrication oil mist lubrication and oil lubrication methods.
