The RSH heavy-duty seals replace the RS1 seals currently used. Fig. 4 shows the difference between the two seal designs. The lip of the RS1 seal makes radial contact with the outer diameter of the inner ring. With the RSH seal, the lip of the seal is in contact axially with the inner ring in a groove at the side and incorporates a secondary lip.

V-ring seals are mounted on shafts and their thin, tapered lip seals against a surface (counterface) at right angles to the shaft. No special demands are placed on the surface finish of the shaft seating and the V-rings act as flingers, since they have an interference fit on the shaft and rotate with it.

In terms of seal history, the crimped case seal, or CCS, is a relative newcomer, entering the market about 10 years ago. The crimped case seal's hallmark design feature is that it can use as little as 2 components: the sealing lip and case. This is in contrast to a traditional design that usually requires 4 components to accomplish the same task.
