011.20.280

The 011.20.280 external tooth four points contact ball slewing bearing delivers high load capacity and smooth rotational performance in demanding industrial environments. Designed with an external gear teeth configuration, this bearing integrates seamlessly with drive systems for precise 360-degree rotation in applications such as cranes, excavators, and solar tracking systems. Its four-point contact ball design enables simultaneous handling of axial, radial, and moment loads, ensuring stability under dynamic or uneven forces. The hardened raceways and high-carbon chromium steel construction provide exceptional durability, with a static load rating of up to 280 kN and dynamic load capacity of 95 kN. Precision-ground gear teeth (module 8, Grade 6H) ensure minimal backlash and efficient torque transmission, while integrated seals protect against contaminants like dust and moisture, extending service life in harsh outdoor or high-particulate conditions. Pre-lubricated with high-temperature grease, the 011.20.280 operates reliably in temperatures from -25 degree to +80 degree and complies with ISO 12944-5 corrosion resistance standards. Common uses include robotic welding arms, wind turbine yaw systems, and medical imaging equipment requiring low-noise, maintenance-free operation.
