FIELD: mechanical engineering.
SUBSTANCE: invention can be used in units with preload. Proposed antifriction bearing contains outer and inner races with conical rolling paths and stop bead on one of races. One of races is furnished with means for unloading rolling elements in form of local cavity. Conical rolling elements are arranged between races. Means for unloading rolling from working load is made on working surface of stop bead of one of races.
EFFECT: provision of relief of rolling elements from working load, increased service life of bearing, improved conditions of lubrication of bearing and prevention of bearing wedging.
