Difference between deep groove ball bearing and angular contact bearing

Release time: 2020-08-15 10:19:53 Views: 189

Also belong to rolling bearing, what is the difference between deep groove ball bearing and angular contact bearing? In this issue, we will explain the similarities and differences between them in detail.

What they have in common

? ? ? Deep groove ball bearing and angular contact ball bearing are representative rolling bearings, which are widely used. They can bear radial load or both radial and axial load. They are suitable for high-speed rotation and occasions requiring low noise and low vibration. The sealed bearing with steel dust cover or rubber seal ring is filled with grease in advance, and the bearing with stop ring or flange in the outer ring can not only bear radial load but also bear radial and axial load at the same time The size of the maximum load bearing is the same as that of the standard bearing, but the inner and outer rings have another filling groove, which increases the number of balls and increases the rated load.

The difference between them

1、 Different types and load directions:

1. Deep groove ball bearing:

6800-2rs deep groove ball bearing

Deep groove ball bearing is the most common type of rolling bearing. It mainly bears radial load, but also can bear radial load and axial load at the same time. When it only bears radial load, the contact angle is zero. When the deep groove ball bearing has large radial clearance, it has the performance of angular contact bearing and can bear large axial load. The friction coefficient of deep groove ball bearing is very small and the limit speed is also very high.

2. Angular contact ball bearing:

? ? ? There are contact angles between the rings and the ball of angular contact ball bearings. The standard contact angles are 15 / 25 and 40 degrees. The larger the contact angle is, the greater the axial load capacity is. The smaller the contact angle is, the better the high-speed rotation is. The single row bearing can bear radial load and unidirectional axial load. DB combination, DF combination and double row angular contact ball bearing can bear radial load and bidirectional axial load. DT combination is suitable for In the case of large unidirectional axial load and insufficient rated load of single bearing, ACh type bearing with small ball diameter and large ball number is mostly used for machine tool spindle. In general, angular contact ball bearings are suitable for high-speed and high-precision rotating occasions.

2、 Structural differences:

Deep groove ball bearings and angular contact ball bearings with the same internal and external diameters and widths have the same inner ring size and structure, while the outer ring size and structure are different

1. Double shoulder on both sides of outer ring raceway of deep groove ball bearing, while single shoulder is generally used for angular contact ball bearing;

2. The curvature of outer ring raceway of deep groove ball bearing is different from that of angular contact ball, and the latter is often larger than the former;

3. The position of outer ring raceway of deep groove ball bearing is different from that of angular contact ball bearing, and its specific value is related to the contact angle degree of angular contact bearing;

3、 In terms of application:

1. The use of the two is different. The deep groove ball bearing is suitable for bearing radial force, small axial force, combined axial and radial load and moment load, while angular contact ball bearing can bear single radial load and large axial load (varying with contact angle), while double pair bearing (different matching mode) can bear bidirectional axial load and torque load.

2. The limit speed of angular contact ball bearing with the same size is higher than that of deep groove ball bearing.

4、 Economic aspect

Since the performance of angular contact bearing is better than that of deep groove ball bearing, the cost of angular contact bearing with the same specification is higher than that of deep groove ball bearing. Therefore, when selecting bearings, we must consider the economy while meeting the performance requirements.

Well, this issue of small and micro bearings to share here, I hope to help you in the purchase of deep groove ball bearings and angular contact bearings. Thank you for reading and sharing with useful friends!
