gab.ru Берг АБ bergab@ya.ru Тел. (495)-228-06-21, Industrial факс shaft seals (495) 22 Mechanical seals These mechanical seals are designed for use under severe service conditions at relatively low peripheral speeds. They offer reliable protection against solid and liquid contaminants as well as leak-proof retention of lubricant. The seals were originally developed for off-road and tracked vehicles but have been found to be equally suitable for a range of other applications where effective protection is required against sand, soil, mud, water etc. These applications include N all types of mixers, N sand treatment equipment, N conveyors and other construction equipment, N agricultural machinery, N washing equipment, N grinding mills and other comminution equipment, N ore dressing equipment, and N mining equipment. Fig 84 The mechanical seals from SKF (fig 84) consist of two identical sealing rings and two similar nitrile rubber Belleville washers (cup springs). The sealing rings are of wear and corrosion resistant steel and have finely finished sliding and sealing surfaces. Sealing is assured even against thin oils, such as SAE 10W40 oils. The Belleville washers of nitrile rubber provide the necessary uniform face loading and positive sealing at the bore and outside diameters. The outside diameter of the washers adapts to the form of the bore in which they are mounted and there are no special demands in respect of surface finish. gab.ru Берг АБ bergab@ya.ru Тел.
