Comparison of Crossed Roller Bearings and Traditional Roller Bearings and Their Application Fields

Title: Comparison and Application Field of Cross-Roller Bearing and Traditional Roller Bearing

Introduction:

Roller bearings as essential components in modern industrial manufacturing have been widely applied in various industrial equipment, machine tools, and engineering machinery. However, with the arrival of the 4.0 industrial revolution, high precision, high performance, and high efficiency modern industrial manufacturing are constantly pursuing innovation and development, and technology is also facing continuous updates and upgrades. This article will compare the performance of cross- roller bearings and traditional roller bearings, as well as their application fields, providing more technical support and references for readers.

1. Characteristics of Cross-Roller Bearings

1. Outstanding rotational precision

Cross-roller bearings have excellent rotational precision, with the cross-rolling design of the rollers forming an angle of 90 each other and the rollers being guided by a or a separated block, which can prevent rollers from tilting or engagement between rollers, effectively preventing the increase in torque. Moreover, cross-roller bearings do not have contact or locking phenomena on the non-rolling side, and because the outer and inner rings of the standard type cross- roller bearings are divided in structure, the clearance can be adjusted, and even with pre-pressure, high-precision rotation movement can be achieved.

2. Simplified installation and operation

The standard type of cross-roller bearings can be divided into two outer rings or inner rings, and after the rollers and are installed, they are fixed together, and the installation is achieved by

3. High load capacity and high radial and axial loads

Because of its unique design, cross-roller bearings have a stronger capacity and a more robust structure, so more and more designs now use more compact cross-roller bearings, which not only saves material costs but also simplifies the design, higher precision, and higher stability, as well as better load capacity and higher radial and axial loads.

2. Comparison with Traditional Roller Bearings

1. Rotational precision comparison

Traditional roller bearings have a relatively low rotational precision, and may suffer from contact or engagement phenomena on one side of the roller, resulting in increased vibration and noise. However, cross-roller bearings have excellent rotational precision, which can effectively prevent this from happening.

2. Installation and operation comparison

Traditional roller bearings require specialized tools for installation, making the operation more complicated. Cross-roller bearings installation is much simpler, and can achieve the ideal load state by making installation and operation very simple.

3. Load capacity comparison

Cross-roller bearings have a higher load capacity than traditional roller bearings, which can meet the needs of large and medium-sized machine tools for radial and axial loads. However, the load capacity of traditional roller bearings is relatively lower, suitable for small and medium-sized machine tools.

3. Application fields of Cross-Roller Bearings

1. CNC machines

Cross-roller bearings have high precision and stability in the high-speed and high-precision of CNC machines, and can ensure the stability and accuracy of high-speed and high-precision machining to achieve higher processing quality and production efficiency.

2. General high-precision machines

Cross-roller bearings are commonly used in general high-precision machines, such as high-precision CNC machines, precision grinders, and coordinate grinders, etc. They can effectively improve the precision, speed, and stability of the machine, reduce lateral and radial loads, and ensure the machining accuracy and surface quality.

3. Automotive and aerospace industries

Cross-roller bearings are widely used in the automotive and aerospace industries, such as automobile and aerospace engines. They can withstand high loads, high precision, and high radial and axial loads, ensuring the stability and precision of engine operation.

Conclusion:

In summary, cross-roller bearings have characteristics such as high precision, stability, simple installation, and high load capacity, and are suitable for various applications, including CNC machines, general high-precision machines, and automotive and aerospace industries. They can effectively improve the accuracy, stability, and efficiency of machine tools, and achieve higher processing accuracy, stability, and load capacity.
