Provide an in-depth introduction to the structure, principle, and characteristics of fully loaded cylindrical roller bearings.

Fully loaded cylindrical roller bearings are a common type of rolling bearing widely used in heavy-duty machinery and equipment. It has a simple structure, high load-bearing capacity, and good rigidity, and can withstand large radial loads and certain axial loads. The following will provide an in-depth introduction to the structure, principle, and characteristics of fully loaded cylindrical roller bearings.

1. Structure:

A fully loaded cylindrical roller bearing consists of an inner ring, an outer ring, a roller, and a cage. The inner and outer rings are matched with the shaft and seat holes respectively, and the rollers roll between the inner and outer rings. The cage is used to maintain the spacing between the rollers. The rollers of a fully loaded cylindrical roller bearing are cylindrical in shape and have a diameter equal to the axial length, hence it is called a fully loaded cylindrical roller bearing.

2. Principle:

Fully loaded cylindrical roller bearings reduce friction losses and withstand and transmit loads through rolling friction. When the shaft is subjected to radial load, the rollers roll along the raceway of the inner and outer rings, evenly distributing the load between the rollers and the raceway. Due to the large length of the rollers, fully loaded cylindrical roller bearings can withstand greater radial loads compared to other types of bearings.

3. Features:

(1) High load-bearing capacity: Fully loaded cylindrical roller bearings can withstand large radial loads and certain axial loads, suitable for heavy-duty mechanical equipment.

(2) Good rigidity: Due to the large roller length of fully loaded cylindrical roller bearings, they can provide good rigidity and are suitable for high-speed and high-precision working conditions.

(3) Strong adaptability: Fully loaded cylindrical roller bearings are suitable for various working conditions, including high temperature, low temperature, and high speed.

(4) Easy installation and maintenance: The fully loaded cylindrical roller bearing has a simple structure and is relatively easy to install and maintain.

Fully loaded cylindrical roller bearings have the characteristics of simple structure, high load-bearing capacity, good rigidity, and strong adaptability. It is suitable for heavy mechanical equipment that can withstand large radial loads and certain axial loads. When selecting and using fully loaded cylindrical roller bearings, it is necessary to make reasonable selection and maintenance based on specific working conditions and load requirements to ensure their normal operation and extend their service life.
