CROWNED OUTER RACE TO REDUCE
EFFECTS OF EDGE LOADING
Edge loading of full complement needle bearings causes
skewing and end thrusting which contribute to premature bearing failure.
In those installations where it is impractical or too costly to provide
for perfect alignment, crowned bearing O.D.'s provide compensation for
misalignment between the cam follower and the surface of a slanted track
or cam. The radius also eliminates skidding and thrusting typical when
bearing is in contact with a flat, circular cam. Bearing life will be
increased in those problem applications where standard flat bearing
surfaces have proven troublesome.
All standard cam followers and cam yoke rollers are
available with crowned outer races. Add suffix C to standard
designations. Example: A 3/4" sealed cam yoke roller which is part
number YR-3/4-X becomes YR-3/4-XC when specified with crown.
