Retention and exclusion
In many applications, the exclusion of
contaminants is just as important as lubricant
retention. The use of a seal with a secondary
(dust) lip in addition to the primary lip, such as
in the CRWHA1 (fig 12) will often suffice.
Another way of mastering the problem of
simultaneous retention and exclusion is to use
two seals aranged in opposite directions, e.g.
two CRW1 (fig 13) or two HDS2 (fig 14) radial
shaft seals.
Highly efficient double action seals are also
obtained by using two opposing V-ring seals
(fig 15) with a thrust washer machined on
both sides situated in between the seals.
Under extremely difficult conditions the use
of the HDDF mechanical seals, (fig 6), is
recommended, providing that the sliding
velocity of the mating surfaces lies within the
permissible range.
