Applications:
Four-point contact bearings, also known as single-row angular contact ball bearings, are versatile bearings designed to support combined radial and axial loads while accommodating tilting moments. Their unique design features an inner ring with two raceways and an outer ring with a single raceway, allowing for contact with both inner and outer ring raceways simultaneously. Here are some common applications of four-point contact bearings: Crands and Slewing Rings, Robotics and Automation, Wind Turbines, Slewing Bearings, Aerospace and Defense, Medical Imaging Equipment, Indesing Tables and Turntables, Telescopes and Observatory Equipment, Material Handling Systems, Precision Rotary Tables.
In summary, four-point contact bearings play a critical role in a wide range of applications across various industries, providing robust support for rotating components while accommodating combined radial and axial loads, tilting moments, and misalignment. Their versatility, durability, and reliability make them indispensable components in modern machinery, equipment, and systems.
