The Advantages Of Ball Bearing Compared With Sliding Bearing

What is ball bearing
Ball bearing is a kind of rolling bearing, the spherical alloy steel ball is installed in the middle of the inner and outer steel ring, in the rolling way to reduce the friction in the process of power transmission and improve the efficiency of mechanical power transmission.
Ball bearing components
Ball bearings mainly contain four basic components: ball, inner ring, outer ring and retainer.
The performance of ball bearings
Ball bearings are generally used in low load mechanical transmission equipment.Because the bearing area of ball bearings is small, it is easy to suffer serious mechanical damage at high speed, so needle roller bearings are often adopted in the mechanical transmission of heavy load to increase the bearing surface, improve the mechanical transmission efficiency, and reduce the mechanical damage.Ball bearings change the friction mode of bearings, the use of rolling friction, this way more effectively reduce the friction phenomenon between bearing surfaces, improve the service life of fan bearings, so the service life of the radiator will be extended.
The use of ball bearings
The purpose of the ball bearing is to determine the relative position of the two parts of the shaft and the bearing seat and to ensure its free rotation, while transferring the load between them.At high speeds, this use can be expanded to include free rotation with little wear in the bearings.Ball bearings are used in a variety of machines and equipment with rotating parts.The ball bearing has small starting friction and suitable working friction, can bear radial and axial combined load, is insensitive to lubrication interruption, has no self-excited instability phenomenon and is easy to start at low temperature.

The advantages of ball bearing compared with sliding bearing
In the design of mechanical parts, rolling bearings and sliding bearings are often used. Compared with sliding bearings, rolling bearings have the following advantages:
(1) In general working conditions, the friction coefficient of rolling bearings is small and will not change with the change of the friction coefficient, which is relatively stable.Small starting and running torque, small power loss, high efficiency.
(2) The radial clearance of the rolling bearing is small, and it can be eliminated by axial pretightening, so the running accuracy is high.
(3) The axial width of rolling bearings is small, and some bearings bear radial and axial composite loads at the same time, with compact structure and simple combination.
(4) Rolling bearings are standardized parts, with a high degree of standardization, and can be produced in batches, so the cost is low.

The price of ball bearing
The price of ball bearing is affected by many factors such as market, material and quotation. If you want to know the specific price of ball bearing，please contact us to make enquiries.
