Double Row Slewing Bearing

Design Principle: The two rows of balls cooperate with each other,and the outer and inner rings are equipped with precise raceways,enabling axial,radial and tilting moment loads to be evenly distributed on each ball. Performance Features: Strong Load-bearing Capacity: It can simultaneously bear large axial,radial and tilting moment loads.-High Stability: The two-row ball structure ensures stable rotation under heavy loads,reducing vibration and shaking. Long Life: High-quality materials and advanced manufacturing processes improve the wear resistance and fatigue resistance of the bearing. Customization Options: Support for customized special surface treatments (such as hard chromium plating to enhance corrosion resistance),non-standard sizes,special mounting holes and keyway designs.

Roller Arrangement and Load Distribution: The two rows of balls are arranged in an orderly manner on the raceways. When an axial load is applied,the two rows of balls share the load together; the radial load is transmitted through the contact between the balls and the raceways; the tilting moment is balanced by the different forces on the two rows of balls. Lubrication and Sealing: Grease Lubrication: High-performance lithium-based lubricating grease is used,which is suitable for most conventional working conditions and provides good lubrication and anti-rust protection. Oil Lubrication: For high-speed or heavy-load applications,a centralized oil supply system can be used to ensure that the bearing is fully lubricated and cooled. Sealing Design: The standard non-contact labyrinth seal can effectively block dust and impurities; in harsh environments,the triple-lip seal can provide more reliable protection. Thermal Management: Reasonable structural design and low-friction materials reduce frictional heat generation,ensuring that the bearing maintains a stable operating temperature during long-term operation.
