Types of ball and roller bearings is much

Types of ball and roller bearings is much,usually ball and roller bearings include Deep groove ball bearing,Angular contact ball bearing,Thrust ball bearing,Spherical ball bearing,Cylindrical roller bearing,taper roller bearing,spherical roller bearing,etc.
In the design of mechanical parts, ball and roller bearings are often used. Compared with sliding bearings,ball and roller bearings have the following advantages and disadvantages.
the advantages for types of ball and roller bearings:
(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 axial width of types of ball and roller bearings is small, and some bearings bear radial and axial composite loads at the same time, with compact structure and simple combination.
(3) Types of ball and roller bearings are standardized parts, with a high degree of standardization, and can be produced in batches, so the cost is low.
Defect for types of ball and roller bearings
(1) Types of ball and roller bearings the rolling body and the pipe contact area is small, especially the ball bearing, the impact resistance is poor.

(2) Because of the structural characteristics of rolling bearings, the radial clearance is relatively large, resulting in large vibration and noise.
(3) the life of ball and roller bearings is reduced under high speed and heavy load.
(4) the inner and outer rings of rolling bearings adopt an integral structure, instead of a partial structure, resulting in more difficulties in the installation of bearings in the middle of the long shaft.
