Full ball high temperature bearings

970 full ball high temperature bearing structure is full ball, use with the pressure of the kiln car equipment use, and very durable. This type of bearing has small coefficient of friction, simple structure, and easy to achieve high manufacturing accuracy. Size range and form variation, applied in kiln car, baking, steel mill, metallurgy and other industries, is one of the most widely used types in mechanical industry, mainly bear radial load, can also bear a certain amount of axial load, applicable to work in very high temperature, can withstand great temperature differences, and ordinary grade rolling bearings are not suitable. High temperature bearing main play according to the rolling bearing raw materials, construction, internal structure processing process specifications, lubrication standards four aspects of reliability design, a greater level to achieve a variety of different working conditions demand.
970 full ball high temperature bearing internal structure without keeper, only rolling body combination, full rolling body, load for with keeper rolling bearing 1.5 times, 600 ℃ series of high temperature deep groove ball bearings, ordinary grade with white high temperature grease lubrication, this kind of lubricating grease is containing poly diol and high purity graphite based compounds, together called high temperature grease, this grease does not flow out, no carbon plus 1 time can top Most of the year, about half a year without adding. It has no residual volatilization of polyglycol at about 200℃, and forms high pure graphite solid lubrication. It is applicable to the working standard of about 600℃ and speed＜500r/min. It is checked once in 2 months up and down for ordinary grade operation. If there is no more dry lubricating film shown by bright metal flash marks on the raceway, the said high temperature resistant grease lubrication should be added. In the -50 to +300 ℃ temperature environment, 100 rpm speed can be free of lubrication long-term operation.
970 full ball high temperature resistant bearing ordinary grade is manufactured according to ordinary size tolerance, and bearing clearance is much higher than ordinary grade rolling bearing, thus ordinary grade is not suitable for high speed operation occasions. But the ordinary grade can be in the 500 rpm speed of long-term operation. Therefore, rolling bearing after special treatment to resist corrosion and improve the running performance index, its size tolerance with the standard tolerance will have a mild deviation value. The deviation value has no influence on the installation or the operation of the rolling bearing.
970 full ball high temperature bearings are commonly used in ceramics, brickwork, glass, smelting, refractory insulation materials, baking, mining, metal surface treatment, plastics, petrochemical equipment and other machinery and equipment manufacturing supporting facilities applications, such as high temperature tunnel kilns, roller kilns, mine cars, etc.
