New cotton equipment due to dustproof,  heat and high speed requirement, the rolling bearing performance and packaging transportation use a large number of seal bearing. These bearing operat a certain period, because the internal lack of oil, leading to bearing dry grinding and damage. Such as import air spinning machines of sealed bearings, quantity, the material good, but use of a few years, for inability to clean and add grease, make the seal bearing a large number of damage scrap, increased the equipment failure and unnecessary spending.

Introduce two simple and effective cleaning and refueling method. The first kind of sleeve cleaning refueling method, applicable to bearing housing the ends for clearance seal bearing. The method is to soak in bearing the kerosene 1 h a 2 h, and then based on the bearing outside diameter size, making special socket, already can clean, and can go. Inner sleeve bearing outside diameter is bigger than 0.05 mm to 0.08 mm, a bearing a lighter slightly. Water roller bearing damage phenomenon NSK case analysis cleaning refueling steps: sleeve join the amount in kerosene, will hand pressed into the bearings, use bearing clearance itself, will kerosene out, repeated 1 ~ 2 times; Clean and dry after the rain will add the sleeve for grease, bearing into sleeve with pressure in fall gently press, how much bearing oiling according to demand flexible. The second is applicable to special totally closed bearings, and its a head of a clearance and positioning screw holes. Use positioning screw holes and bearing clearance are interlinked, first the bearing soaked in kerosene in 1 h ~ 2 h, import bearing of chemical elements in the performance of the influence of steel with a special and nozzle, oil gun inhaled kerosene, repeatedly scored bearing 2 ~ 3 times, drench after working for oil gun will add grease can.

These measures shall apply to a variety of imported or domestic seal bearing and special seal bearing, the bearing can get regular clean, will be able to extend its life, and can save a lot of money and reduce the occurrence of bad car
