Angular Contact Ball Bearings

• Double row angular contact ball bearings

• roll thrust bearings

They can limit the bidirectional axial displacement of the shaft or housing with a contact angle of 30 degrees. In addition, it provides a stiffer bearing arrangement and can withstand overturning moments.

The structure of double row angular contact ball bearing

The structure of the double-row angular contact ball bearing consists of two inner and outer conical outer rings and a double-row angular contact spherical inner ring.

Stable contact is maintained between the inner and outer rings through a set of steel balls, which form an angle on the contact angle so that the double-row angular contact ball bearings can withstand positive and reverse axial forces and large radial force. The contact angle of the bearing's inner and outer rings can be changed to meet the working requirements under different load and speed conditions.

The outer ring of the double-row angular contact ball bearing has two ballways, and the inner ring has one ballway. This design will improve the load capacity of the bearing.

Naming rules for double-row angular contact ball bearings

The naming rules of double-row angular contact ball bearings generally consist of one or more prefixes bearing basic codes and bearing suffixes.

For example, 3206A-2RS1TN9/C3MT33 bearing, among them, 3206 is the basic code of the bearing, 3 is the bearing type, representing the double row angular contact ball bearing, 2 is the bearing size standard, representing the 02 standard series, 06 is the inner diameter code, representing the inner diameter is 30mm. A-2RS1TN9/C3MT33 is the suffix code of the bearing, which consists of five parts: internal design, external design (seal, snap ring groove, etc.), cage design, precision clearance preload standard, and grease.

Application of double-row angular contact ball bearings

Since double-row angular contact ball bearings can bear radial and axial loads from two directions, the application range of double-row angular contact ball bearings is relatively wide.

In the automotive field, double-row angular contact ball bearings are often used in front-wheel hubs of cars (some models also use double-row tapered roller bearings of the same size). In addition, there are other application scenarios, such as in mechanical equipment, textile equipment, and other fields, where double-row angular contact ball bearings can be used.
