We can guarantee that our Double row ball Slewing bearing match global standards and are competitively priced. “ Double row ball Slewing bearing by Kavitsu is an example of highest quality standards. These eight point double row ball slew bearings are manufactured using precise machinery. The specially designed CNC groove grinding machine ensures perfect 8 point ball contact is maintained, which in turn makes sure that the slew bearing has higher life. Our range for single row ball starts at 400 mm and goes up to 3200 mm. Slewing Ring Bearing Details: MOC rings: 42CrMO / C45 MOC Cages : Nylon 6 / Nylon 66 Range : 100 mm to 3200 mm Geared ( Internal / External), Ungeared. Applications: Excavators Crawler Cranes Port Cranes Wind Wills Double row ball slew bearing comes in three various types. Double row ball slewing ring bearing ungeared Double row ball slewing ring bearing external geared Double row ball slewing ring bearing internal geared This type of slewing ring bearing is generally chosen where there are heavy loads as compared to single row bearing. The ball size for this type of bearing varies from 30mm to 50mm.By using proper software and research, the ball size is chosen, which ensures proper selection of axial load and torque. The material selection is done based on the input parameters and the requirement of the customer. The material that is used in this type is generally 42CrMO or C45. Sometimes, for boom cranes and tower cranes, the material required is 50Mn. The balls are made of High chromium steel, generally denoted by 100Cr6 and the cages are made of either nylon 6 or nylon 66 depending on the load conditions. Such type of slewing ring bearing are usually used where the static load is high and the installation space is limited. The applications for such types of slew ring bearings are: Wind applications for yawing and pitching of the blades Marine applications Tower cranes which has medium range working radius Loading and unloading cranes on Cargo ports Blacodised Bearing Combined Bearing Driver Seat Bearing Double Row Slewing Ring Bearing Dual Axis Solar Tracker Excavator Bearings External Geared Slew Bearing Internal Geared Slew Bearing Single Row Ball Slewing Bearing Contact Us +91 9503911711 Download PDF Kavitsu Bearing is the best Slew ring bearings , Slewing Bearing , Slew drive , combined bearing , Turn Table Slew Bearing , Single row ball Slewing bearing , Double row ball Slewing bearing , three row roller slew ring bearing , Excavator Bearings , Dual Axis Solar Tracker , Manufacturer, Exporter in United States, Turkiye, China, Turkey, United Kingdom, Germany, Netherlands, Singapore, Canada, Australia, Japan, France, United Arab Emirates, South Korea, Finland, Spain, Nigeria, Egypt, Philippines, Indonesia, Europe, Italy, Russia, ABU DHABI, Bhutan, New Jersey, Thailand, UAE, UK, USA, Vietnam, Bahrain, Kuwait. FAQ What is a Double Row Slewing Ring Bearing? A Double Row Slewing Ring Bearing is a large-diameter bearing with two rows of balls designed to support higher axial, radial, and tilting moment loads while providing smooth 360° rotation. It is ideal for heavy-duty industrial applications. Why is a Double Row Slewing Ring Bearing used? It is used to provide higher load capacity, greater stability, improved rigidity, and longer service life compared to single-row slewing bearings. Where is a Double Row Slewing Ring Bearing used? Double Row Slewing Ring Bearings are widely used in excavators, crawler cranes, port cranes, wind turbines, marine equipment, tower cranes, and heavy material handling machinery. How does a Double Row Slewing Ring Bearing work? It uses two rows of precision steel balls between the inner and outer rings to distribute heavy loads evenly, enabling smooth rotation while supporting axial, radial, and moment loads simultaneously. Which industries use Double Row Slewing Ring Bearings? These bearings are commonly used in construction, mining, renewable energy, marine, port handling, heavy engineering, steel plants, and material handling industries. How do you choose the right Double Row Slewing Ring Bearing? Choose a bearing based on load capacity, bearing diameter, gear type (internal, external, or ungeared), mounting dimensions, operating conditions, and application requirements. What maintenance is required for a Double Row Slewing Ring Bearing? Regular lubrication, bolt torque checks, seal inspection, cleaning, gear inspection, and periodic wear monitoring help maximize bearing performance and service life.
