How do deep groove ball bearings support radial loads?

Deep groove ball bearings are a common type of rolling bearing whose design and structure enable it to effectively withstand radial loads. The special internal design of deep groove ball bearings enables them to withstand radial loads from different directions through the rolling motion of the balls, thereby ensuring the reliable operation of mechanical equipment.

Deep groove ball bearings are composed of inner rings, outer rings, steel balls and cages. Among them, the inner ring and outer ring are set on the shaft and bearing seat respectively, and the steel ball is located between the inner and outer rings, and the correct gap is maintained through the cage. Key to the design is the rolling motion of the ball.

When an external force acts on the bearing, due to the spherical shape of the ball, it is distributed very evenly between the inner and outer rings. These balls contact the inner and outer rings in a point-contact manner, forming guide points, thereby generating radial support in different directions. This layout successfully transfers the radial load acting on the bearing to the ball, and then transfers it to the inner and outer rings through the rolling motion of the ball, achieving assistance to the radial load.

In this case, the rolling motion is crucial. When an external force creates a radial load on the bearing, the ball will roll along the trajectory of the inner and outer rings instead of sliding. This rolling motion is more powerful than sliding friction, which can reduce friction losses and improve bearing performance and life. At the same time, rolling motion can also share weight, allowing the bearing to slightly bear radial loads from different directions, maintaining the stability of the equipment.

The layout of deep groove ball bearings also takes into account factors such as the number of balls, ball diameter and bearing size to meet weight requirements under different working conditions. By adjusting these parameters, radial masses of different strengths and specifications can be assisted, making deep groove ball bearings widely used in many mechanical equipment.
