Key Features of Rolling Bearings

Source: Bearing Network | Date: April 7, 2014

Rolling bearings are widely used in various mechanical systems due to their unique advantages and performance characteristics. Compared to plain bearings, rolling bearings offer several benefits that make them a preferred choice in many applications. Firstly, rolling bearings are easy to use and have standardized designs, which allows for mass production by specialized manufacturers. This ensures excellent interchangeability and versatility across different industries. Secondly, they require less starting torque and power loss, with a friction coefficient typically ranging between 0.98 and 0.99, which is higher than that of hybrid plain bearings. This makes them more energy-efficient during operation. Thirdly, rolling bearings can operate under a wide range of loads, speeds, and temperatures, and minor changes in working conditions usually do not significantly affect their performance. Additionally, most types of rolling bearings can handle both radial and axial loads simultaneously, while maintaining a compact design in terms of axial dimensions. Moreover, rolling bearings are easy to lubricate, maintain, and protect, which contributes to their long service life and reliability. However, rolling bearings also have some disadvantages. For example, they generally have larger radial dimensions compared to other bearing types. Under high-speed or heavy-load conditions, their lifespan may be shortened. In addition, they tend to produce more vibration and noise during operation. Whether you're selecting bearings for industrial machinery, automotive systems, or other applications, understanding the features of rolling bearings can help you make an informed decision.
