Product data – general HMSA10 seal Fig. 12 Retention and exclusion In many applications, the exclusion of contaminants is just as important as lubricant retention. <strong>Seals</strong> with an auxiliary lip, like the HMSA10 seals († fig. 12), are appropriate for these applications. Another option is to use two seals installed in opposite directions († figs. 13 and 14) or two opposing V-rings († fig. 15) with a spacing washer. Under extremely tough operating conditions, <strong>SKF</strong> recommends using HDDF metal face seals († fig. 6 on page 18), provided that the sliding velocity of the mating surfaces lies within the permissible range. Two seals in opposite direction Fig. 13 Two seals in opposite direction Fig. 14 V-ring Fig. 15 20
CRW1 seals Fig. 16 Separating two liquids When an application has to keep two liquids from coming into contact with each other, there are two suitable solutions. These solutions, which depend on the availability of space and required efficiency, include: 1 • the use of two separate seals († figs. 16 and 17), positioned with their lips facing in oppos ite directions • the use of HDSD1 double-lip seals († fig. 18) Fig. 17 In both alternatives, the sealing lips must be spring-loaded. When using an HDSD seal, it is very important to provide a means to lubricate the sealing lips, i.e. the cavity between the sealing lips must be filled with grease prior to installation or during operation via lubrication holes drilled through the metal case into the cavity.
