Angular contact ball bearings and deep groove ball bearings are symbolic roller bearings. What is the difference between them?
01 type and load orientation are different;
Deep groove ball bearing:
Deep groove ball bearing is a more common type of roller bearing. The key can bear radial load, and can also bear radial load and axial load. When it bears only radial load, the contact angle is zero. When the deep groove ball bearing has a large radial clearance, it has the characteristics of angular contact rolling bearing and can carry a large axial load. The friction resistance of the deep groove ball bearing is small and the limit speed ratio is also very high.
Angular contact ball bearing:
There is a contact angle between the throwing ring and the ball. There are three standard contact angles: 15 / 25 and 40 degrees. The larger the contact angle is. The greater the axial load working capacity, the rolling bearings can bear radial load and unilateral axial load. DB composition, DF composition and self-aligning bearing angular contact ball bearings can bear radial load and dual axial load. DT composition is suitable for places with large unilateral axial load and insufficient stable load of individual rolling bearings. ACh type rolling bearings are used quickly. The ball diameter is small and the number of balls is large. Most of them are used for lathe spindle. In general, angular contact ball bearings are suitable for fast and high-precision rotating places.
Angular contact ball bearing
02 different in the field of construction;
Both sides of the outer section of deep groove ball bearing have double stop shoulders, while angular contact ball bearings are widely single stop shoulders;
The refractive index of the outer section of the deep groove ball bearing is different from that of the angular contact ball, and the latter one usually exceeds the former one;
The external section of deep groove ball bearing is different from that of angular contact ball bearing. For other parts, the actual standard value is considered in the design scheme of angular contact ball bearing, which is related to the degree of contact angle;
03 different purposes;
The main uses of the two are different. Deep groove ball bearings are suitable for bearing radial force, small axial force, axial and radial cooperative load and torque load, while angular contact ball bearings can bear single radial load and large axial load (different with contact angle), and double connection matching (different with matching method) can bear double axial load and torque load.
The limiting speed ratio of deep groove ball bearing and angular contact ball bearing is different. Under the same specification, the limiting speed ratio of angular contact ball bearing is higher than that of deep groove ball bearing.
