Do you know the classification and characteristics of angular ball bearings?

angular ball bearings can bear radial and axial loads at the same time, and can work at higher speeds. Mainly used in metallurgical equipment, mining machinery, construction machinery, paper machinery, wind turbines, semiconductors, machine tools, gear devices, motors (motors), pumps and compressors, injection molding machines, motorcycles and other fields.

Today we will learn about the classification and characteristics of angular ball bearings. ‍

No.1 single row angular ball bearings
This bearing has a contact angle, so it is suitable for bearing axial loads in one direction, or combined loads.
Structurally, the axial component force is generated after bearing radial load, so two bearings are used oppositely, or two or more bearings are used in pairs. Single row angular contact ball bearings can use the preload method to improve rigidity, so they are suitable for machine tool spindles with high rotational accuracy.

No.2 Paired double angular ball bearings
Combining two sets of radial bearings into pairs becomes a paired double bearing. Usually paired duplex bearings are composed of the same angular contact ball bearings.

Paired double angular ball bearings are divided into three categories:
1. Back-to-back configuration
Can bear radial load and axial load in two directions.
The distance between the action points is large, so it is suitable for applications with large moment loads.

2. Face to face configuration
Can bear radial load and axial load in two directions.
Compared with the back-to-back duplex, the distance between the action points is small, so the moment load capacity is poor.

3. Tandem configuration
Can withstand radial loads and axial loads in one direction. The axial load is supported by two bearings, so it is used for occasions where the load in one direction is large. ‍

No.3 Double row angular ball bearings
The single-row angular contact ball bearing is double-connected back-to-back, and the inner ring and the outer ring are each integrated into one structure. It can withstand axial loads in two directions and has moment load capacity. Can be used as fixed end bearing. Has a two-way thrust bearing capacity.

No.4 point angular ball bearings
Four-point contact ball bearing is a single-row angular contact ball bearing with separate inner and outer rings. The inner ring is divided into two parts, and one bearing can bear axial loads in two directions.
The contact angle is 35°, and the axial load capacity is large, which is suitable for bearing pure axial load or synthetic load with large axial load. Interchangeable with face-to-face or back-to-back angular contact ball bearings.
