Factors to Be Considered in Selecting Ball Bearing Track Rollers


Ball bearing track roller means that the rolling body of the bearing is a roller, and the contact surface with the ring is arc-shaped. The outer spherical bearing refers to the ring of the bearing, and the contact surface with the housing hole of the bearing is arc-shaped. Both types of bearings can realize the self-aligning function. The difference is that roller bearings carry much more load than spherical bearings. The outer spherical bearing has a much higher speed under the same load condition. Various types of rolling bearings have different characteristics and are suitable for different use situations of various machines. In general, thrust bearings and angular contact bearings are used for thrust loads; ball bearings are usually used for high-speed applications, and roller bearings are used for heavy radial loads.

High-speed track and roller bearing systems are essential in applications requiring both high load capacity and high rotational speeds. For instance, high-speed track and roller bearing components are crucial in railway systems, where they ensure the smooth and efficient operation of high-speed trains. These bearings reduce friction and wear, enabling trains to achieve higher speeds while maintaining stability and safety. In industrial machinery, high speed track and roller bearing systems are used in turbines, compressors, and high-speed spindles, where they handle heavy radial loads and high rotational speeds effectively.


1. The space and position of the ball bearing track roller occupied by the machine


In mechanical design, the size of the shaft is generally determined first, and then the ball bearing track roller is selected according to the size of the shaft. Usually, ball bearings are used for small shafts, and roller bearings are used for large shafts. However, when the bearing is limited in the diameter direction of the machine, needle roller bearings, extra-light and ultra-light series ball or roller bearings are used; when the bearing is limited in the axial position of the machine, narrow or extra narrow series ball or roller bearings are available.


2. The size, direction and nature of the load on the ball bearing track roller


Load is the most important factor in the selection of bearings. Roller bearings are used to bear heavy loads, ball bearings are used to bear light or medium loads, and bearings made of carburized steel or bainite quenched can withstand shock and vibration loads. In terms of the direction of the load, deep groove ball bearings, cylindrical roller bearings or needle roller bearings can be used when bearing pure radial loads. When bearing a small pure axial load, thrust ball bearings can be selected; when bearing a large pure axial load, thrust roller bearings can be selected. When the bearing bears combined radial and axial loads, angular contact ball bearings or tapered roller bearings are generally used.


3. Alignment performance of ball bearing track rollers


When the center line of the shaft is different from the center line of the bearing seat, there is an angle error, or the shaft is less rigid due to the large distance between the two supports of the shaft, and it is easy to be bent or tilted by force, the self-aligning machine with good self-aligning performance can be selected. Ball or spherical roller bearings, and outer ball bearings. These bearings will keep working even if the shaft is slightly tilted or bent. The quality of the bearing's self-aligning performance is related to its allowable misalignment. The larger the misalignment value, the better the self-aligning performance.


4. Rigidity of ball bearing track rollers


The rigidity of a ball bearing track roller refers to the amount of force required for the bearing to produce unit deformation. The elastic deformation of rolling bearings is very small, which can be ignored in most machines, but in some machines, such as machine tool spindles, bearing rigidity is an important factor, and cylindrical and tapered roller bearings should generally be used. Because when these two types of bearings are under load, their rolling elements and raceways are in point contact, and their rigidity is poor. In addition, the bearing can also achieve the purpose of increasing the rigidity of the support through preloading.
