Product Description Slewing bearing catalogue for tower crane type RKS.061.25.1204 dia 1338*1119*68mm Product DescriptionFour-point contact ball slewing turntable bearings consist of two ring seats. Compact structure, light weight, steel ball and arc track contact at four points, can bear axial force, radial force and overturning moment at the same time, has strong dynamic load. Technical FeaturesFour-Point Contact Design:Supports combined radial, axial, and moment loads in a single bearing, optimizing space and load distribution.Integrated External Gear:Precision-machined gear teeth enable direct torque transmission, eliminating the need for separate gear components.High Load Capacity:Engineered raceway geometry ensures even stress distribution across all four contact points, enhancing durability.Low Friction Operation:Advanced ball-to-raceway contact reduces energy loss and heat generation.Precision Manufacturing:Manufactured to tight tolerances for smooth rotation and minimal backlash.Material Options:High-grade steel or corrosion-resistant materials for demanding environments. Functional AdvantagesCompact Design:Combines bearing and gearing functions, reducing system complexity and installation space.High Rigidity:Stable performance under heavy or dynamic loads.Reduced Maintenance Needs:Robust construction and optimized lubrication options extend service intervals.Versatile Mounting:Suitable for both horizontal and vertical configurations.

Rollers are 1:1 cross-arranged.Can be bear axial force, overturning moment and large radial force at the same time,and widely used in lifting transportation, construction machinery and precesion products.Double row ball slewing bearingsThis kind of bearings can support high static loads with simple structures. They are mainly used in situations with variation load position and direction and continuously rotating. Main applications of this kind of bearings are deck hoisting, mining and material handling etc.Three row roller slewing bearingThree row roller bearing able to bear all kinds of loads at the same time, it is the largest one of the four structural products with large axle and radial dimensions and firm structure. Especially suitable for heavy machinery requiring larger diameter, such as bucket wheel stacker and reclaimer, wheel crane, marine crane, port crane, ladle turret,large tonnage truck crane,heavy machinery and so on.
