In The Same Working Conditions Of The Same Type Of Rolling Bearing, Usually The Larger The Size, The Longer Its Life.
A:In the same type of rolling bearing under the same working conditions, the larger the size is, the longer the life is, is right, according to the pressure theorem, the smaller the contact surface is, the greater the pressure (pressure) is (such as jack), similarly, the small rolling bearing inside and outside the longitude is very small, the ball direct longitude is small, and the bearing inside and outside the contact surface is small, the greater the force it bears, It and the bearing inside and outside the friction force is also large; Large rolling bearing inside and outside by the increase, the ball by the increase and the number of direct, and the bearing inside and outside by the contact surface will increase, the ball to bear the force is reduced, it and the bearing inside and outside by the friction force is small, so high-power equipment with large bearings.
