Exclusion
of mud, dirt, and water in off-road wheel applications requires
sophisticated shaft
seals. In some instances, dual seals are used,
as in Figure 219. Alternatively,
non-standard single seals with rubber on both the I.D. and
the O.D. may
be used; an example of this is shown in Figure
220. This seal has its own running
surface.

“Because
of the many ways in which shaft seals may be
configured, they are common in a wide variety
of automotive applications.”
