Product Description:
The Ball Bearing 92-20 0741/1-07242 Anti-corrosion Swing Circle Gear is designed for construction machinery. It is suitable for various applications, including excavators, drilling rigs, mining equipment, cranes, offshore equipment, vehicles, machine tools, and wind turbines.

This bearing belongs to the four-point contact ball slewing turntable bearings category. It consists of two ring seats and has a compact structure and lightweight design. The steel ball and arc track contact at four points, enabling the bearing to bear axial force, radial force, and overturning moment simultaneously. It can handle strong dynamic loads.

Another type of bearing is the single-row cross roller slewing bearing. It is composed of two or three rings and has a compact structure and high manufacturing accuracy. The rollers are cross-arranged, providing excellent load-bearing capacity. This type of bearing is commonly used in lifting transportation, construction machinery, and precision products.

Double row ball slewing bearings are suitable for situations with varying load positions and directions. They can support high static loads with their simple structure. Applications for this type of bearing include deck hoisting, mining, and material handling.

The three-row roller slewing bearing is the largest among the four structural products. It can bear various loads simultaneously and has a firm structure. It is especially suitable for heavy machinery requiring larger diameters, such as bucket wheel stackers and reclaimers, wheel cranes, marine cranes, port cranes, ladle turrets, large tonnage truck cranes, and other heavy machinery.
