DEFINITION

Classification: 384/452

Radial bearing with separate thrust bearing; radial ball-thrust roller:

(under subclass 445) Subject matter comprising rolling elements some of which take mainly radial load and some of which take mainly thrust load.

(1) Note. Where a single element takes both type of load, the patent is classified according to the load sustaining in the greater proportion. If this is not clear then the presumption is that the greater load is in the radial direction.

(2) Note. Bearings where there is a ball taking radial load and a roller taking axial load specifically are classified in this subclass.
