New cotton equipment due to dustproof, and heat and high speed requirements, the use of the large number of seal NSK bearings. These bearing operation after a certain period, because the internal lack of oil, lead to bearing dry grinding and damage. Such as import air suction of sealed bearings, quantity, the material is good, but use after a few years, for not cleaning and added a 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 FAG 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. 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 SKF 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, in 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 NTN bearing, the bearing can get such as regular cleaning refueling, will be able to extend its service life, and can save a lot of money and reduce the occurrence of bad car.
