What is Double Row Ball Slewing Bearing？
Double row ball slewing bearing is a special type of slewing bearing, which is a structural design in slewing bearings. Compared with the traditional single-row ball slewing bearing, the double-row ball slewing bearing has some significant structural differences.
Main features and structure:
Double row raceway: Compared with the single row ball slewing bearing which has only one raceway, the double row ball slewing bearing has two parallel raceways, namely the inner raceway and the outer raceway. A series of steel balls or rollers form rolling contact between the two raceways to achieve rotation.
High load-bearing capacity: Since the double-row ball slewing bearing has two raceways, it can withstand greater radial and axial loads than the single-row ball slewing bearing. This makes it excellent in rotating equipment that needs to handle larger loads.
Higher rigidity: The double row ball slewing bearing has two parallel raceways, which makes it have higher rigidity and flexibility resistance. This makes it excellent in applications requiring high-precision positioning and stable operation.
Multi-purpose: Double row ball slewing bearings can be used in various industrial and mechanical equipment, such as large engineering machinery, port machinery, cranes, wind power generation equipment, bridge swivels, etc.
Adaptability to complex environments: It has good corrosion resistance and anti-pollution capabilities, and is suitable for use in some complex environments, such as offshore equipment and coastal facilities.
Generally speaking, the double row ball slewing bearing is a slewing bearing with a special structural design. It uses two parallel raceways to achieve greater load-bearing capacity and rigidity. It plays an important role in heavy machinery and engineering equipment, providing reliable rotating solutions.
