The future development prospects of bearings

  • Maintenance-Free bearings are key mechanical parts in the manufacturing industry chain. They can not only reduce friction, but also support loads, transmit power and maintain positioning, thereby promoting the efficient operation of equipment. The bearing industry can be considered as a traditional industry dominated by enterprises, which has been operating efficiently for decades.

    1. Customization

    In the industry, the concentration trend of bearings is becoming more and more obvious, and the surrounding parts of the bearing have become an inaccessible part of the bearing itself. This type of bearing is developed to minimize the number of bearing parts in the final assembly product. It can reduce equipment costs, increase reliability, provide easier installation, and extend service life. The demand for customized bearings has increased significantly worldwide, and has greatly stimulated the interest of customers. The bearing industry is turning to the development of new special bearings. Therefore, bearing suppliers provide professional customized bearings to meet the special requirements of agricultural machinery, automotive turbochargers and other applications.

    1. Life and condition monitoring

    Bearing designers use sophisticated simulation software tools to better match the bearing design with actual operating conditions. Nowadays, the computer and analysis codes used in bearing design and analysis have reasonable engineering certainty, which can predict bearing performance, life and reliability. The predictive ability exceeds the level of ten years ago and does not require expensive and time-consuming experiments or field tests. As people place higher demands on existing assets in terms of increasing output and increasing efficiency, it becomes more and more important to understand when problems start to occur. Unexpected equipment failures can be costly and can have catastrophic consequences, leading to unplanned production shutdowns, expensive parts replacements, and safety and environmental issues. Bearing condition monitoring can dynamically monitor various equipment parameters, helping to detect failures before catastrophic failures occur. Bearing original equipment manufacturers continue to develop "smart bearings" with sensing functions. This technology enables the bearing to continuously transmit its operating status through internally powered sensors and data acquisition electronics.

    1. Materials and coatings

    Even in harsh working conditions, advanced materials can extend the life of the bearing. The bearing industry currently uses materials that were not easily available a few years ago. These materials can greatly improve performance and efficiency. In some cases, special bearing materials can enable heavy equipment to operate effectively without lubricants. . These materials and specific heat treatment conditions and geometric structures can handle extreme temperatures and processing conditions, such as particle contamination and extreme loads.

    In the past few years, the improvement of the surface texture of rolling elements and raceways and the addition of wear-resistant coatings have accelerated significantly. These bearings are very suitable for high stress, high impact, low lubrication and high temperature conditions.

    As the bearing industry responds to emission regulatory requirements, improved safety standards, lighter products with lower friction and noise, increased reliability expectations, and fluctuations in global steel prices, more and more companies are integrating digitalization into the U-Joint With Pressed Bearings manufacturing industry. Gain a global advantage.
