Customization is available for this product, allowing for specific requirements and customized requests.

Product Description:

The Customized Rotary Table Crane Slewing Ring Bearings VLA 20 0944 N Outer Gear is a four-point contact ball slewing turntable bearing. It consists of two ring seats and has a compact structure and light weight. The steel ball and arc track contact at four points, enabling it to bear axial force, radial force, and overturning moment simultaneously. It has a strong dynamic load capacity.

Another type of slewing bearing is the single-row cross roller slewing bearing. It is composed of two or three rings and has a compact structure, light weight, and high manufacturing accuracy. It requires small assembly gap and high installation accuracy. The rollers are cross-arranged, allowing it to bear axial force, overturning moment, and large radial force at the same time. This type of bearing is widely used in lifting transportation, construction machinery, and precision products.

Double row ball slewing bearings are simple in structure and can support high static loads. They are suitable for situations with variation load position and direction, as well as continuous rotation. Main applications for this type of bearing include deck hoisting, mining, and material handling.

The three-row roller slewing bearing is the largest of the four structural products. It can bear all kinds of loads simultaneously and is known for its large axial and radial dimensions and firm structure. It is especially suitable for heavy machinery requiring a larger diameter, such as bucket wheel stackers and reclaimers, wheel cranes, marine cranes, port cranes, ladle turrets, large tonnage truck cranes, and heavy machinery.
