Comparison of Load Capacity between Ball Bearings and Roller Bearings

Ball bearings and roller bearings are two common types of rolling bearings, and they have significant differences in load-bearing capacity. The following is a detailed comparison of the load-bearing capacity of these two types of bearings

First. Characteristics and load carrying capacity of ball bearings

Ball bearings, also known as spherical bearings, are a kind of mechanical bearings widely used in automobile, motor, instrumentation and other industries, whose inner and outer rings are spherical in shape and can bear radial and axial loads. Ball bearings are widely used because of their small and lightweight dimensions.

The bearing capacity of ball bearings is affected by the number of balls in the inner ring and outer ring and the size of the ball diameter. Under the same external dimensions, the larger the ball diameter, the greater the load carrying capacity. However, the number of balls in a ball bearing is limited, so the load carrying capacity has some limitations. Under the same size, the size of ball bearing capacity is generally between roller bearings and plain bearings.

Second, the characteristics and load carrying capacity of roller bearings

Roller bearings, also known as rolling bearings or roller bearings, are a type of bearing commonly used in high load and high speed applications. Roller bearings are similar in structure to ball bearings, but use cylindrical rollers that are able to withstand greater radial and axial loads.

Roller bearings have a greater number of rollers inside and longer roller lengths than ball bearings. As a result, roller bearings have a higher load carrying capacity and are more fatigue resistant than ball bearings of the same size. Under the environment of high speed and high load, the use of roller bearings can better ensure the safety and reliability.

Comparative analysis

Ball bearings and roller bearings both have the function of bearing, but their bearing capacity has some differences. The bearing capacity of ball bearings is relatively small, while roller bearings are more suitable for carrying the weight and load of machinery and equipment.

When choosing ball bearings or roller bearings, it is necessary to choose according to the specific load situation and working environment. For lighter loads and lower speeds, ball bearings are a good choice; while for high loads and high speeds, roller bearings are more suitable.
