    Recently, Shandong Youmete Bearing Co., Ltd. (hereinafter referred to as "Youmete") successfully released a new research and development technology "four point contact deep groove ball bearing". This product breaks through the limitations of traditional bearing design, perfectly integrates the universality of deep groove ball bearings with the high load-bearing capacity of four point contact bearings, and fills the industry gap. This innovative achievement marks a crucial step for Chinese bearing enterprises in the field of high-end precision manufacturing.

    Research and Development Background: Cracking Industry Pain Points

    Against the backdrop of industrial equipment upgrading and intelligent transformation, bearings, as the core components of mechanical transmission, are facing more stringent working conditions. Although traditional deep groove ball bearings can adapt to high-speed rotation and radial loads, their bi-directional axial load-bearing capacity is insufficient; Although four point contact ball bearings can withstand bidirectional axial forces, their complex structure results in high costs and difficulty in miniaturization. Yoomete has focused on this contradiction and spent three years tackling it. Through collaborative innovation in materials science, structural design, and precision machining technology, they have created a "four point contact deep groove ball bearing" that combines the advantages of two types of bearings.

    Technological Breakthrough: Four Core Innovations

    1. "Deep groove peach shaped" composite raceway design

    Yumet pioneered the dual-mode raceway structure of "deep groove raceway peach shaped groove", which maintains the continuous raceway characteristics of deep groove ball bearings while optimizing the contact angle and curvature radius to form a stable four point contact between steel balls under bidirectional axial loads. The axial bearing capacity is increased to more than three times that of traditional deep groove ball bearings.

    2. Split type inner ring self-locking technology

    Adopting a high-precision split type inner ring design, the assembly stability is ensured through a patented self-locking structure, avoiding the dynamic eccentricity problem caused by the split structure of traditional four point contact bearings, while reducing installation complexity by 30%.

    3. Nanoscale surface treatment process

    Introducing ion implantation surface strengthening technology to form a superhard wear-resistant layer on the surface of the bearing raceway, reducing the friction coefficient by 18%, increasing the maximum speed by 25% compared to ordinary four point contact bearings, and extending the service life to 1.8 times the ISO standard

    4. Intelligent simulation system for all working conditions

    A bearing dynamic load simulation platform based on AI algorithms accurately predicts the stress distribution and fatigue life of bearings under composite loads, ensuring the reliability of products under extreme working conditions such as wind power pitch systems and industrial robot joints.

    Application scenario: Empowering high-end equipment upgrades

    In the field of industrial robots:

    Suitable for collaborative robot joint modules, it can simultaneously withstand radial forces and frequent directional axial impact forces in narrow spaces, helping to improve the efficiency of flexible production lines.

    New energy equipment:

    Adapt to wind power variable pitch bearings and electric vehicle drive systems to solve the problem of early bearing failure under high vibration and bidirectional torque loads.

    Precision Machine Tools and Aerospace:

    Satisfy the bi-directional positioning requirements of precision turntables, replace the combination scheme of "thrust bearings radial bearings", and reduce installation space and weight by 50%.

    Customer verification and market prospects

    At present, the product has passed the T Ü V Rheinland certification in Germany and completed installation testing in leading enterprises such as XCMG and Xinsong Robotics. Data shows that under the same operating conditions, the failure rate of Yumet four point contact deep groove ball bearings is reduced by 42% compared to traditional solutions, and the comprehensive cost savings exceed 20%. The company plans to achieve mass production in the third quarter of 2024, with an expected annual production capacity of 2 million sets, aiming to cover the global high-end equipment manufacturing market.

    The Chief Technology Officer of Youmete stated, "Four point contact deep groove ball bearings are not only a breakthrough in technical parameters, but also a revolution in design concepts. In the future, we will continue to iterate around the three directions of 'lightweight, intelligent, and long-life', promote the evolution of bearings from standard components to customized functional modules, and provide core support for intelligent manufacturing in China

    Shandong Youmeite Bearing Co., Ltd. has demonstrated the innovative strength of Chinese bearing enterprises to the world with the starting point of "four point contact deep groove ball bearings". The launch of this product not only redefines the technological boundaries of high load bearings, but also injects strong momentum into the localization replacement of high-end equipment, marking the official entry of China's bearing industry into a new era of "smart manufacturing leading".
