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.
Advantages of deep groove ball bearings:
Deep groove ball bearing has the advantages of low manufacturing cost, simple structure, variety and so on. It is widely used in various industries and is one of the more commonly used bearings. It has the following characteristics:
1. Small friction coefficient, high speed.
2.The size range is wide, with a certain aligning ability.
3.Simple structure, low manufacturing cost, mass production, can achieve high precision.
4.Can bear large radial load, when the radial clearance increases, can bear two directions of alternating axial load.
5.In reasonable maintenance and use of the environment of high durability, low maintenance cost.
