Slewing bearings are essential mechanical components designed to support heavy axial, radial, and overturning loads. These bearings are commonly used in a wide range of applications where rotational movement is required under extreme conditions. They are typically equipped with oil holes, sealing devices, and through-holes, making them adaptable for various operational environments. One of the key advantages of slewing bearings is their compact design, which allows for easy installation and maintenance. Their ability to rotate smoothly and guide accurately makes them ideal for use in complex machinery. They are widely applied in industries such as construction, mining, metallurgy, wind energy, marine, port operations, oil and gas, chemical processing, light manufacturing, medical equipment, food processing, automotive, robotics, aerospace, radar systems, and military equipment. Slewing bearings come in different types based on their structural layout. These include four-point contact ball bearings, cross-rolled cylindrical (tapered) roller bearings, double-row four-point contact ball bearings, double-row ball bearings, and ball-roller combination bearings. There are also three-row cylindrical roller combination bearings. Depending on whether they have teeth or not, these bearings can be classified as toothed or non-toothed, with the teeth arranged either internally or externally. Each type of slewing bearing is designed to meet specific load requirements. For example, four-point contact ball bearings offer high dynamic load capacity, while cross-rolled cylindrical roller bearings provide superior static load capacity. The three-row cylindrical roller combination bearings allow for increased load capacity in the vertical direction, with different raceways and roller groups handling various types of loads. This design leads to a significant reduction in the diameter of the bearing under the same load conditions. SBI Company has established itself as a leading manufacturer in the field of slewing bearings. With years of experience and a strong focus on innovation, SBI has built solid partnerships with well-known companies both domestically and internationally. Over 80% of its slewing bearings are exported globally, reflecting the company's commitment to quality and performance. Whether you're working on large-scale machinery or precision equipment, understanding the features and applications of slewing bearings is crucial for ensuring smooth and efficient operation.
