What is the design principle of Single Row Angular Contact Ball Bearings?

Single Row Angular Contact Ball Bearings are specially designed bearings that can withstand radial and axial loads. Unlike ordinary deep groove ball bearings, the design principle of angular contact ball bearings is based on the contact angle between the ball and the inner and outer rings. The unique feature of this bearing is that its ball contacts the inner and outer rings at a certain angle instead of vertically, which enables it to withstand large axial loads while bearing radial loads.

The contact angle of single row angular contact ball bearings (usually 15°, 30° or 40°) has a crucial impact on its performance. The contact angle determines the amount of axial load that the bearing can withstand. When the contact angle is large, the axial load capacity of the bearing is stronger, while when the contact angle is small, the radial load capacity of the bearing is more prominent. The contact angle allows the load to be transmitted through the contact surface between the ball and the inner and outer rings during the operation of the bearing, so that it is more evenly distributed, effectively reducing the pressure on the contact surface, reducing wear, and improving the durability and stability of the bearing.

Another important advantage of this design is that it can maintain high performance at high speeds. Since the contact surface between the ball and the inner and outer rings is small, the friction inside the bearing is low, which reduces the heat generated by friction and improves the operating stability and life of the bearing. Especially in some applications that require high-speed rotation, such as machine tool spindles, aerospace equipment, etc., single-row angular contact ball bearings can operate at a higher speed without performance degradation due to excessive friction.

Single-row angular contact ball bearings also have high rigidity and precision, which makes them perform well in high-precision mechanical equipment. Because the angular contact design allows the bearing to withstand large axial forces, it is very suitable for use in equipment that needs to withstand not only large radial loads but also axial loads, such as motors, pumps, reducers, etc. This type of bearing is widely used in industrial equipment, precision instruments and high-speed machinery, especially in environments that require high precision and high stability.
