In-depth analysis of composite roller bearings.

Oct 21, 2024

Combined bearings, also known as composite roller bearings or combined roller bearings, are a bearing system that integrates multiple functions. They were first designed by Europeans and widely used in various mechanical equipment. With its unique structure and excellent performance, this bearing has excellent performance in load bearing, wear resistance, corrosion resistance and impact resistance, and has become an indispensable key component in modern industry.

Structural composition

The composite roller bearing is mainly composed of an axle head, main roller, side roller and cover plate. The axle head is used as the installation base and is connected to the plate with round holes by welding, and then assembled with the gantry or other structures. The main roller is the core bearing body in the composite roller bearing, which mainly bears the load in the vertical direction. Its design emphasizes wear resistance, corrosion resistance and impact resistance. The main roller usually adopts a full roller structure to ensure stable operation under heavy load conditions.

The side roller is used as an auxiliary bearing body, which mainly bears the load in the horizontal direction and is also required to have high wear resistance, corrosion resistance and impact resistance. The side roller is essentially a roller bearing without a full needle roller in the inner ring. It is closely matched with the spindle and the shaft head to form a stable support structure.

The function of the cover plate is to fix the main roller, side roller, and shaft head together to form a whole, ensuring the stability and reliability of the bearing system. In addition, the assembly method of the composite roller bearing is flexible, and conventional nuts or stainless steel nuts can be selected for fixing according to customer-specific requirements to adapt to different working environments and use conditions.

Performance characteristics

The reason why the composite roller bearing can stand out among many bearing types is mainly due to its excellent performance characteristics. First, its high load-bearing capacity enables the composite roller bearing to easily cope with various heavy-load conditions and ensure the stable operation of mechanical equipment. Secondly, the improvement of wear resistance and corrosion resistance greatly prolongs the service life of the bearing and reduces maintenance costs. In addition, the enhanced impact resistance enables the bearing to maintain a good working condition under harsh working conditions, improving the overall reliability of mechanical equipment.

Application field

Composite roller bearings are widely used in various mechanical equipment that require high load, high wear resistance, high corrosion resistance and impact resistance. For example, in heavy equipment such as shield machines, cranes, and conveyors, composite roller bearings, as core components, undertake the important tasks of transmitting power, supporting weight, and bearing impact. At the same time, in high-tech fields such as radar, aerospace, etc., composite roller bearings also play an irreplaceable role, providing a strong guarantee for the precise control and stable operation of equipment.

Technological Development

With the advancement of science and technology and the development of industry, the manufacturing technology of composite roller bearings is also constantly innovating and improving. For example, in terms of material selection, R&D personnel are committed to developing new materials with higher strength, higher toughness, and better wear resistance to meet the increasingly stringent working conditions. In terms of manufacturing technology, high-precision processing and mass production of composite roller bearings are achieved by introducing advanced processing equipment and optimizing process flow. In addition, the application of intelligent and automated technology has further improved the production efficiency and product quality of composite roller bearings.

In summary, combined roller bearings, with their unique structure and excellent performance, play an increasingly important role in modern industry. With the continuous advancement of technology and the continuous expansion of application fields, composite roller bearings will surely show broader prospects and unlimited possibilities in future development.
