摘要

An antifriction bearing assembly and seal installation for oscillatory motion about a longitudinal axis comprising a pair of longitudinally spaced, thin-walled elastomeric seals defining a hermetically sealed chamber which contains fluid lubricant. The seal comprises an intermediate portion having a plurality of bellows-like folds which have a pair of parallel straight portions concentric with the axis of rotation and interconnected at one end by a radially directed semicircular segment.
