Single-row Angular Contact Ball Bearing
Single-row angular contact ball bearings are rolling bearings designed to withstand both radial loads and unidirectional axial loads. The contact surface between the inner and outer rings has a certain angle (usually 15°~40°), which improves the axial load capacity of the bearing.
Advantages
- Strong load capacity
- Good high-speed performance
- High rigidity
- Can be used in pairs
التطبيقات
- Machine tool spindles
- Electric motors and generators
- Automotive gearboxes and wheels
- Robotic joints and industrial automation equipment
- Aerospace and medical equipment
Technical analysis of single-row angular contact ball bearings
Basic characteristics
Single-row angular contact ball bearings (Single-Row Angular Contact Ball Bearing) adopt a special raceway design, which can simultaneously bear radial force and unidirectional axial force. The core of its performance lies in the contact angle design (common 15°, 20°, 25°, 30° and 40°). The angle is positively correlated with the axial load capacity, but the radial load capacity will be reduced accordingly.
Structural advantages
Directional load characteristics
Can only bear unidirectional axial force, and bidirectional force requires bearing pair installation (back-to-back/face-to-face configuration).
High rigidity design
The inclined raceway structure provides excellent rigidity, which is particularly suitable for high-precision application scenarios such as precision machining equipment.
Dynamic performance
The axial load capacity is significantly better than that of deep groove ball bearings
The radial load capacity is relatively limited
The optimized friction coefficient (0.001-0.0015) ensures high-speed operation stability

Technical summary
This type of bearing has outstanding performance in axial load and rotation accuracy through optimized contact angle design. In practical application, it should be noted that:
The radial load capacity is limited
Bidirectional force needs to be installed in pairs
The speed, load and accuracy requirements should be considered comprehensively when selecting
As a key component of modern mechanical transmission system, its performance directly affects the overall operation quality and life of the equipment, and plays an irreplaceable role in the field of high-end equipment manufacturing.
