Deep groove ball bearings and angular contact ball bearings are representative rolling bearings, so what are the differences between angular contact bearings and deep groove ball bearings?

Angular contact ball bearings can bear radial load and axial load at the same time. Can work at higher speeds. The larger the contact angle, the higher the axial load carrying capacity. The contact angle is the angle between the line connecting the contact point of the ball and the raceway in the radial plane and the vertical line of the bearing axis. High-precision and high-speed bearings usually take a contact angle of 15 degrees. Under the action of axial force, the contact angle will increase. In this way, if the outer ring of the bearing is fixed, if it is subjected to an axial force, then it will be surrounded by these two corners, and its force bearing effect will be particularly good, and the precision will be relatively high .

Deep groove ball bearings are the most commonly used rolling bearings. The basic type of deep groove ball bearings consists of an outer ring, an inner ring, a set of steel balls and a set of cages. There are two types of deep groove ball bearings: single row and double row. The structure of deep groove ball is also divided into two types: sealed and open. The open type means that the bearing does not have a sealed structure. seal. The material of the dust-proof sealing cover is stamped steel plate, which simply prevents dust from entering the bearing raceway. The oil-proof type is a contact oil seal, which can effectively prevent the grease in the bearing from overflowing.

It has a simple structure and is convenient to use. It is mainly used to bear radial load, but when the radial clearance of the bearing is increased, it has a certain performance of angular contact ball bearing, and can bear combined radial and axial loads. When the speed is high and thrust ball bearings are not suitable, they can also be used to bear pure axial loads. Compared with other types of bearings with the same specification and size as deep groove ball bearings, this type of bearing has a small friction coefficient and a high limit speed. However, it is not resistant to impact and is not suitable for heavy loads.
