DEFINITION
Classification: 384/49
Ball bearing:
(under subclass 7) Subject matter wherein the linear antifriction element is a ball.
(1) Note. Roller antifriction elements in a linear antifriction bearing often have their own radial bearing systems, which may include ball bearings, but because the linear antifriction element is a roller, these devices are classified in subclass 50 below, and not in this subclass.
(2) Note. Where different embodiments use balls in one embodiment and rollers in another, they are included here.
