First, the details of the use of imported bearings 1, the use of installation carefully carefully not allowed to force stamping, not allowed to hammer directly on the bearing, not allowed to pass pressure transmission rolling body. 2, try to keep the imported bearings and the surrounding environment clean even if the naked eye can not see the smile of dust into the bearings, bearings will increase the wear and tear, vibration and noise. 3, to prevent the corrosion of NSK Bearings Directly take the imported bearings by hand, wash your hands full of sweat, and coated with high-quality mineral oil and then operate in the rainy season and summer, with particular attention to rust. 4, the use of appropriate, accurate installation tools try to use special tools, try to avoid the use of cloth and staple fiber and the like. Second, the daily maintenance bloom bearings 1 spindle spindle bearings in operation, we must fully guarantee the lubrication, and according to the actual use of regular lubricants, not a long time off the oil. Therefore, for the user business, should choose a better and more suitable spindle lubricants. The new special spindle oil can significantly improve the lubrication performance, extend the oil change intervals, extend the life of the spindle and bearing, but also has good rust and corrosion resistance. 2 bearings in the assembly should not be bump and impact, bump and impact easily lead to the collision between the bearing parts, resulting in bearing failure. 3.NSK bearing seat curling should pay attention to control the curling angle, strength and other factors, to avoid the curling unreasonable cause bearing parts deformation failure. 4 on the spindle bearings and billet cleaning problems. Due to the compact structure of the spindle foot, there are many other parts in the spindle foot cavity. Their cleanliness also affects the cleanliness of the working cavity of the bearing. Therefore, the assembly before the use of billet parts pre-cleaning, assembly assembly, and then the assembly billet, including bearings, fine cleaning process is a more reasonable process. 5. Sub maintenance cleaning should pay attention to methods to prevent damage, scratched roller surface. As far as possible to clear the bearing parts of the residue should be washed, suction billet feet internal cleaning method of remaining oil is better. Care should be taken to avoid dumping residue in the bearing parts, resulting in bearing noise, wear failure and other issues.
