* The maximum fillet on the shaft or in the housing that the bearing corner will clear.
† Positive value indicates the effective load center is outside the backface of the cone.
For additional “B” cup dimensions, see pages 173 to 174.
For parts with a “J” prefix, use metric tolerances given on page 199 and fitting practice given on page 201.
Designate bearings with hollow rollers and pinned-type retainers.
Bearing is equipped with seals (and in some instances side rings).
