to fig1 except that the groove is formed in the housing and the housing is sectionalized rather than the shaft the shaft 30 is mounted for high speed movement relative to the sectionalized housing 31 the sections of which are held together by securing means 32 one section of the housing 31 is identified by the numeral 33 and the other section 34 has a groove 35 formed in its inner end to accommodate the continuous annular bearing seal 36 and the elastomeric combined spring and seal 37 the bearing seal 36 and the combined spring and seal 37 are manufactured of the same materials as the bearing seal 27 and ring 29 although of course the latter is of larger diameter because its interior surface bears upon the exterior surface of the bearing seal 36 rather than the interior surface as shown in fig1 fig3 shows the same support structure as shown in fig1 this support structure includes the housing 40 and a sectionalized shaft 41 the latter being constructed identically to the shaft 21 the shaft 41 has a groove 42 formed therein to accommodate a continuous annular bearing seal member 43 and an elastomeric combined spring and seal 44 therebehind the latter and the bearing seal 43 are constructed indentically to the bearing seal and spring of fig1 except that it is constructed without a tang it will be noted that it is of uniform radial dimensions throughout its length it should be.
