What Are the Main Components of a Rolling Bearing?
1 Answers
Rolling bearings consist of four main components: the outer ring, inner ring, rolling elements, and cage. Simply put, any bearing that includes an outer ring, inner ring, and rolling elements can be classified as a rolling bearing. Based on the shape of the rolling elements, rolling bearings are categorized into two main types: ball bearings and roller bearings. Strictly speaking, they are composed of six major parts: the outer ring, inner ring, rolling elements, cage, seals, and lubricating oil. Additional information: 1. Bearings are critical components in modern mechanical equipment. Their primary function is to support rotating mechanical parts, reduce the friction coefficient during operation, and ensure rotational accuracy. Depending on the friction properties of the moving elements, bearings can be divided into two main categories: rolling bearings and sliding bearings. Rolling bearings have been standardized and serialized, but compared to sliding bearings, they have larger radial dimensions, higher vibration and noise levels, and are more expensive. 2. Rolling bearings support rotating shafts and their components, maintaining the proper working position and rotational accuracy of the shaft. They are easy to use and maintain, reliable in operation, have good starting performance, and offer relatively high load-bearing capacity at medium speeds. Compared to sliding bearings, rolling bearings have larger radial dimensions, poorer vibration damping capabilities, shorter lifespans at high speeds, and produce more noise.
