Abstract
A roller bearing apparatus including inner and outer rings defining a pair of raceway spaces, a plurality of rollers arranged in oppositely axially inclined rows each occupying one of the raceway spaces, and a guide member. The guide member includes a ring between the roller rows and oppositely extending shortened prongs or stubs extending only a short distance between the rollers so as not to take up space that otherwise could be used for one or more additional rollers. The pocket bottoms are angled to skew the rollers to promote roller precession or indexing. Alternatively, the guide member can include a reduced number of larger prongs to replace one or more of the stubs.
