Classification Of Ball Bearings

Ball bearings are widely used in transmission systems due to their numerous advantages, including low friction resistance, high maximum speed, and affordable price. There are four common types of ball bearings:

1. Deep groove ball bearings:

Characteristics: These bearings primarily withstand radial loads and are the most widely used type.

Applications: Deep groove ball bearings can primarily withstand radial loads, but they also perform well under combined radial and axial loads. They have low friction coefficients and are suitable for high-speed conditions. With a simple structure, they are easy to manufacture with high precision, making them suitable for mass production.

2. Angular contact ball bearings:

Characteristics: These bearings have a higher axial load capacity.

Applications: Angular contact ball bearings have advantages such as high speed, high precision, and low noise and vibration. They are mainly used in situations where the axial force is high and deep groove ball bearings are not suitable.

3. Self-aligning ball bearings:

Characteristics: These bearings have self-aligning capabilities.

Applications: Self-aligning ball bearings are suitable for situations where the shaft is prone to deflection or where the bearing seat hole positioning accuracy is poor in long shafts. However, due to their lower rigidity, they are suitable for low-speed conditions where strict requirements on noise and vibration are not present.

4. Thrust ball bearings

Features: can only withstand unidirectional axial load

Application: These bearings are designed for use under high axial loads, low speeds and high torques.

In conclusion, ball bearings are extensively used in transmission systems due to their various advantages. The different types of ball bearings, including deep groove ball.
