YRT Rotary Table Bearings
YRT bearings, especially YRT turntable bearings, occupy a key position in high-end mechanical equipment due to their excellent characteristics. Its features include: 1. High precision: achieve millimeter-level motion accuracy, repeatable positioning accuracy up to micron level, meet the needs of high-precision rotation and detection. 2. High stiffness: excellent radial, axial and torsional stiffness, ensuring stable performance under heavy loads and complex working conditions. 3. Compact and diverse structure: compact design reduces weight while maintaining strong load-bearing capacity, and a variety of models meet different application requirements. 4. High load-bearing capacity: three-row roller structure provides stable axial and radial load-bearing capacity to meet complex load challenges. 5. Long life and low friction: using high-quality materials and processes, wear-resistant and fatigue-resistant, low friction torque reduces energy consumption and noise. 6. Convenient installation and maintenance: with self-contained mounting holes and oil holes, simplifying the installation process; reasonable sealing structure reduces maintenance costs. 7. Wide application: the core is used in high-precision equipment such as CNC machine tools and machining centers, and also covers military industry, aerospace and other fields.
