  • Race (bearing) Wikipedia

    In the case of ball bearings, the bearing has inner and outer races and a set of balls. Each race is a ring with a groove where the balls rest. The groove is usually shaped so the ball is a slightly loose fit in the groove. Thus, in principle, the ball contacts each race at a single point.A comprehensive review on convolutional neural network in,Dec 05, 2020· The single point motor bearing faults simulated by the electro-discharge machining were tested in this platform, including inner race fault, outer race fault and ball fault. Each fault contains different sizes, i.e. 7 mils, 14 mils, 21 mils, 28 mils, and 40 mils (1mil = 0.001 in.).

All radial ball bearings that require a preload must be loaded axially. When an axial load is applied to the inner ring of the bearing, the race of the inner ring comes in contact with the rolling element and translates this load to the raceway of the outer ring. This creates a line of contact between the inner race, the ball and
