gab.ru Берг АБ bergab@ya.ru Тел. (495)-228-06-21, Industrial факс shaft seals (495) 22 SKF mechanical seals are supplied as readyto-mount cartridge units. A special retainer ring holds the two sealing ring faces together. This not only facilitates mounting but also protects the seal against damage. The retainer is left in position after mounting and provides extra protection for the sliding surfaces during the initial stages of operation. It slowly wears away. The permissible operating conditions for the mechanical seals are given in Table 24. The chemical resistance of the nitrile rubber is dealt with in the section “Chemical resistance”. Installation No special tools are required to mount the mechanical seals. To ease installation it is recommended that the housing bore should have a lead-in chamfer as shown in the product tables. The recommended tolerances for the housing bore are also given in the product tables. A typical application for this type of seal, the drive assembly of an off-road tracked vehicle, is shown in fig 85. Repair kits For repairs where the sealing rings are to be re-used and only the washers are to be replaced, replacement washers can be supplied. They come as “repair kits” which also contain installation instructions and two lintfree cloths for cleaning the sealing rings of the original seal. Appropriate repair kits for individual SKF mechanical seals are listed in Table 25. Table 25.
