    Roller/Ball Combined Slewing Bearings Roller/Ball Combined Slewing Bearings

    The roller/ball combined slewing bearing integrates both rollers and balls within its structure, providing a balanced approach to load management. The rollers engage in line contact with the raceways, delivering high rigidity and stability, while the balls make point contact, enhancing smooth rotation. This combination allows the bearing to effectively manage various loads, including axial forces, radial forces, and overturning moments, making it suitable for demanding applications.

    The dual-row design ensures that each row is optimized for handling specific types of loads, with the rollers supporting heavy axial loads and the balls contributing to rotational accuracy and overall stability. Most of these bearings are designed with an external gear configuration, which generally requires more installation space compared to an internal gear setup but allows for easier maintenance access. If an internal gear or gearless design is preferred, LYXQL can customize the product to meet specific application needs.

    Typically, the rings are manufactured from 42CrMo4 steel, with induction-hardened raceways for enhanced durability. Alternative materials can be used depending on the specific requirements provided by the customer.

    Manufacturing Capability

    LYXQL can manufacture roller/ball combined slewing bearings with an outer diameter of up to 20 meters. The gear module size can go up to 45mm.

    How should Roller/Ball Combined Slewing Bearings be maintained?

    To ensure performance and longevity, proper handling and storage are crucial—especially to avoid damage to the mounting surfaces or gear teeth. For bearings stored over long periods, re-lubrication before installation is strongly recommended to maintain optimal operating conditions.

    How does your company ensure the quality of slewing bearing products?

    We maintain rigorous quality control through a full suite of over 20 advanced testing instruments and inspection systems. These include 11 high-precision coordinate measuring machines (CMMs) from Germany, along with contour meters and roundness instruments from the UK and Germany.
    All production processes comply with GB/T 9001-2016 / ISO 9001-2015 quality management system standards, ensuring our slewing bearings meet the highest reliability and performance expectations.
