Spherical roller bearing, as the core component of rotary table, rotary table in the process of operation, not only must have high bearing capacity, but also need to have high rotary accuracy, high anti-overturning capacity, and high speed capacity. spherical roller bearings are characterized by two raceways in the bearing and spherical rollers. Compared with the traditional combination of thrust bearing and radial centering bearing, the spherical roller bearing has a compact structure and compact size, and simplifies the design of the rotary table, thus reducing the cost of the rotary table. The company has accumulated rich experience in the application of spherical roller bearings on rotary worktables of machine tools, referring to similar foreign products, combined with its own characteristics, developed a series of spherical roller bearings used in rotary worktables of machine tools.

Due to the use of optimized preload, the spherical roller bearing has high stiffness, so the stiffness and accuracy of the rotary table are guaranteed. Our company has spherical roller bearings: high accuracy of operation; Strong ability to resist overturning; Reducing axial length and processing costs, thermal expansion leads to limited changes in geometric dimensions; Nylon separator, low moment of inertia, low starting torque; Optimized preload, high stiffness, small runout; Line contact, rigidity, high precision of guide roller operation; Carburized steel provides excellent impact resistance and surface wear resistance; Simple but well lubricated.

When the bearing is installed, the spherical roller bearing has applied preload to the recommended value at the factory, without having to have a complex installation and adjustment process like the hydrostatic bearing. spherical roller bearings are easy to install, easy to adjust the original installation form or maintenance method. spherical roller bearings are suitable for various types of vertical or horizontal boring machines, as well as vertical grinding, vertical turning and large gear milling machines.
