* The maximum fillet on the shaft or in the housing that the bearing corner will clear.<br />

† Positive value indicates the effective load center is outside the backface of the cone.<br />

For additional “B” cup dimensions, see pages 173 to 174.<br />

For parts with a “J” prefix, use metric tolerances given on page 199 <strong>and</strong> fitting practice given on page 201.<br />

Designate bearings with hollow <strong>roller</strong>s <strong>and</strong> pinned-type retainers.<br />

Bearing is equipped with seals (<strong>and</strong> in some instances side rings).<br />
