Cylindrical Roller Bearings

Cylindrical roller bearings are a common type of rolling bearings with high load carrying capacity and rigidity. This article will introduce the working principle, structural characteristics and application fields of cylindrical roller bearings.

The working principle of cylindrical roller bearings is to use rollers to roll between the inner and outer rings to convert the external load of the bearing into rolling friction, thereby reducing friction loss and energy loss. Compared with plain bearings, cylindrical roller bearings have a lower coefficient of friction and higher rotational accuracy.

The structural features of cylindrical roller bearings mainly include inner and outer rings, rollers, cages and sealing devices. The inner and outer rings are the main parts of the bearing, and they are connected together by rollers and cages. The rollers are cylindrical in shape and carry the load of the bearing by rolling. The function of the cage is to maintain the relative position of the rollers and prevent them from colliding with each other and falling off. The sealing device is used to prevent external pollutants from entering the inside of the bearing and keep the working environment of the bearing clean.

Cylindrical roller bearings have many advantages. First of all, it has a high load-bearing capacity and can withstand large radial and axial loads. Secondly, due to the application of rolling friction, cylindrical roller bearings have lower friction loss and energy loss, which can improve the efficiency and operation stability of mechanical equipment. In addition, cylindrical roller bearings have a simple structure, are easy to install and maintain, and have a long service life.

Cylindrical roller bearings are widely used in various mechanical equipment. For example, it is often used in heavy machinery and equipment such as metallurgical equipment, mining equipment and shipbuilding equipment. In addition, cylindrical roller bearings are also widely used in the fields of automobiles, electric motors, power engineering and aerospace. In these fields, cylindrical roller bearings can provide reliable support and load bearing to ensure the normal operation of equipment.

In summary, cylindrical roller bearings are an important type of rolling bearings with high load carrying capacity and rigidity. It converts the external load of the bearing into rolling friction through rolling friction, reducing energy loss and friction loss.

Self-lubricating bearing

Self-lubricating bearings, also known as rolling bearings or plain bearings, are devices used to reduce friction and wear in mechanical parts. Self-lubricating bearings have better wear resistance and longer life than conventional bearings because they are self-lubricating, reducing reliance on external lubricants.

Deep Groove Ball Bearings

Deep groove ball bearing is a commonly used rolling bearing. It has the advantages of simple structure, convenient use and large bearing capacity, and is widely used in various mechanical equipment. The structure of deep groove ball bearing is composed of outer ring, inner ring, rolling elements and cage. The outer and inner rings are made of steel, heat-treated and precision-machined for hardness and smoothness. The rolling elements are usually made of steel balls, which reduce friction and bearing force by rolling. The function of the cage is to maintain the spacing and relative position of the rolling elements so that they can roll freely.
