What is a ball bearing? Generally speaking ball bearings are made up of inner ring, outer ring, ball and cage, for the inner ring acts to engage the shaft and rotate with the shaft. The outer ring of the ball bearing is matched with the bearing seat to play a supporting role. The frictional resistance is small, the power consumption is small, and the mechanical efficiency is high. These are the characteristics of the ball bearing, and the size for ball bearing is also very standardized, interchangeable, and easy to install and disassemble. For advantage of stable quality, high precision, high speed, little wear and long service life, so the ball bearings are also widely used in various machinery. Lily bearings is the leader of the bearing suppliers.
Ball bearings are also used in a wide range of applications, not only to withstand radial loads but also with two-way axial loads. It is very suitable for many high speed and low noise, low vibration requirements. When the ball bearing is subjected to a pure radial load, the contact angle is zero. When the ball bearing has a large radial clearance, it has the performance of angular contact, generally the friction coefficient is relatively small, and the extreme speed of the bearing is also high, especially in the case of a large high-speed operation, the ball bearing is even more excellent.
For the extreme speed operation, the ball bearings are extremely durable and needn't frequent maintenance. The bearing has a simple structure, very high extreme rotation speed, and many changes in the size and form of the ball bearing, so it has a wide range of applications in the general machinery industry such as precision instruments, low noise motors, and automobiles.
