Bearings are the key mechanical parts in the manufacturing industry chain, which can not only reduce friction, but also support loads, transmit power and maintain positioning, thereby promoting the efficient operation of equipment. The global bearing market is about 40 billion U.S. dollars and is expected to reach 53 billion U.S. dollars by 2026, with a compound annual growth rate of 3.6%. Today we will talk about the focus of bearing research and development and the future development trend:

1. Customization of bearing

In the industry (especially automotive industry), the trend of "integrated bearings" is increasing, and the surrounding parts of the bearing become an inaccessible part of the bearing itself. Special bearing was developed to minimize the number of bearing components in the final assembled product. Therefore, the use of "integrated bearings" reduces equipment costs, increases reliability, provides easier installation, and extends service life. The demand for specific application solutions is increasing substantially on a global scale, and has greatly stimulated the interest of customers. The bearing industry is turning to the development of new special bearings. ZYS can provide professional customized bearings to meet the special requirements of agricultural machinery, automotive turbochargers and other applications.

2. Life prediction & condition monitoring

Bearing designers use sophisticated simulation software tools to better match the bearing design with actual operating conditions. Nowadays, the computer and analysis code used in bearing design and analysis have reasonable engineering certainty, and can predict bearing performance, life and reliability. The predictive ability does not require expensive and time-consuming experiments or field tests. Unexpected equipment failures can be costly and can have serious consequences, leading to unplanned production shutdowns, replacements of expensive parts, and safety and environmental issues. Bearing condition monitoring can dynamically monitor various equipment parameters, helping to detect failures before serious failures occur.

3. Bearing material & coating Even under harsh working conditions, advanced bearing materials can extend the service life of bearings such as hard coatings, ceramics and new special steels. These bearing materials can greatly improve bearing performance and work efficiency. In some cases, special bearing materials 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. For example, the development of tungsten carbide coated balls that are both wear-resistant and corrosion-resistant is a major development. These bearings with advanced materials are very suitable for high stress, high impact, low lubrication and high temperature conditions.

With emission regulatory requirements, improved safety standards, increased reliability expectations and fluctuations in global steel prices, bearing research and development seems to be a strategic decision leading the market.
