How to store rolling bearings

Rolling bearings are coated with an appropriate amount of anti-rust oil and packed with anti-rust paper before leaving the factory. As long as the packaging is not damaged, the quality of NSK motor bearings will be guaranteed. When the bearing is stored for a long time, it is advisable to store it on a shelf 30cm above the ground when the humidity is lower than 65% and the temperature is about 20℃. In addition, the storage place should avoid direct sunlight or contact with cold walls. After long-term storage of bearings with seals, the properties of the grease in the bearings are affected. Bearings removed from their original packaging should be properly protected from corrosion and contamination. Large rolling bearings are placed in a horizontal (perpendicular to the axis) position, and the entire side of the bearing ring should be supported. If the bearing is placed in a vertical position, the thickness of the bearing ring is relatively small, and the weight of the bearing ring and rolling elements may cause permanent deformation of the bearing. Small bearings cannot be taken out of the box and placed in drawers, open shelves and cabinets because they may be contaminated with dirt, dust, etc. When using a new bearing, it is not necessary to remove the grease applied to the bearing for dust protection at the factory. Although the grease applied at the factory has only a little lubricating ability, it does not damage the newly applied oil on the bearing. All tools should be clean and in good condition. Workbenches and assembly work areas should be clean. Assembly work should not be carried out in the welding area or near the machine because of the possibility of welding debris or dust entering the bearings. The installation and maintenance of the bearing plays a positive role in the use of the bearing. In order to give full play to the bearing performance, reduce unnecessary downtime losses, and ensure the smooth and safe operation of the equipment. Installation and maintenance Precautions for bearing use 1) Keep the bearing and its surroundings clean 2) Careful and careful use If the bearing is used carelessly with a strong impact, it will cause cracks, indentations, fractures and other damages to the bearing. 3) Use suitable tools 4) Pay attention to the rust prevention of the bearing and avoid using it in a humid place, and wear gloves so as not to get sweat on it. 5) The user should be familiar with the bearing 6) Develop the operating specifications for the use of the bearing Storage of the bearing and the surrounding clean installation parts Size and processing quality inspection Installation work disassembly work Maintenance (regular inspection) Supplementation of lubricants.
