SKF bearing sales: the long ball bearing rust is there any danger

Compared with metal bearing, ceramic bearing more corrosion grinding, guide rail on the surface of a longitudinal slot or ridge, used to guide, fixed special machine parts, equipment, instruments, etc, low speed, to install the V belt as an example, the first belt set in the small pulley groove, and then turn the big belt wheel, with screwdriver to set the V belt into the large pulley groove. So, 'magnetic' belongs to the magnetic mark, related to protect the pump under the condition of electric leakage of personal property safety, must be properly installed pump grounding, good install leakage switch at the same time. How to determine the bearing can use again and need to change the defect of the bearing can judge bearing used again, according to the bearing damage level, mechanical properties, importance, and operating conditions, the factors related to inspection cycle to decide. Bearing chamber of wear surface oil removal, repair steps: machining and installation accuracy refers to the shaft, bearing, bearing chamber of machining tolerance, surface roughness and assembly accuracy and other technical parameters. Bearing clearance adjustment: according to the method of interval values such as less than a specified value, should be between the upper and lower tile joint surface and gasket to adjust; If answer to minus the gasket is greater than the specified value, or scraping bearing surface to adjust. As we all know the bearing points of high-speed and low-speed? Is it? It is how to distinguish? Due to the use way is different, so they were divided into low-speed bearing and the bearing. After, according to the understanding of the release bearing use, tell everybody the car engine timing kit, clutch kit, etc. , as long as meet the replacement mileage or fixed number of year, even after replacement and no problems, also want to replace all, otherwise easy to appear the situation in that case! Therefore, we in the process of repair cars, some still need to listen to the teacher's advice, maintenance to avoid again soon to repair the car. Is now mostly used lubricating oil and gas or oil mist lubrication and grease lubrication with the method of cooling, the service life of bearing design calculation of bearing and bearing reasonable design of inseparable, bearing selection must calculate the equivalent load bearing. Grease on bearing have very good effect, its adhesion, abrasion resistance, temperature tolerance, rust and lubricity are good, can improve the high temperature oxidation resistance, delay aging, can dissolve carbon deposition, prevent poly metal abrasive dust and oil pollution, the improved mechanical wear, pressure and corrosion resistance. Due to the structure limit, its cage often highlight the height - on inner and outer mm（ Series of different structure and size, height) , often lead to cooperate with the cage, intervene with cage caused by wear, jam, deformation and failure, serious when online burning down bearing fault. Because the steel quenching when heated austenitic actual carbon content is not high, far lower than on the phase diagram shows the equilibrium concentration, so it can absorb carbon ( Or nitrogen) , its reason is carburizing of the surface of the parts has a larger residual compressive stress. Roll diameter surface straightness can not meet the requirements ( Roll diameter surface uneven phenomenon exists) , this kind of phenomenon, in the old roll ( It hasn't reached standards roll) Is widespread.
