What is a Flange Slewing Bearing?

A Flange Slewing Bearing is a specialized type of bearing that combines axial and radial load capacity, enabling a rotating load-bearing platform to simultaneously support both heavy loads and rotational movement. It consists of an inner and outer ring with rolling elements, such as balls or rollers, in between, and a flange that extends from one of the rings. The flange provides mounting points that make installation more straightforward and secure.

Types of Flange Slewing Bearings

There are two primary types of Flange Slewing Bearings, each with unique characteristics:

• Flange Ball Slewing Bearing: This type of slewing bearing features ball-shaped rolling elements, providing smooth and efficient rotational movement. It is suitable for applications requiring low friction, high rotation speeds, and the capability to handle medium loads.

• Flange Roller Slewing Bearing: Equipped with roller-shaped rolling elements, this variant exhibits higher load-carrying capacity compared to its ball counterpart. It is ideal for applications requiring higher axial and radial loads along with moderate rotation speeds.

Both types of Flange Slewing Bearings can be further classified into single-row, double-row, or cross roller configurations depending on the arrangement of their rolling elements.

Features of Flange Slewing Bearings

Flange Slewing Bearings offer several key features that make them stand out from other bearing types:

• High load capacity: Capable of handling both axial and radial loads, flange slewing bearings can support heavy weights while maintaining rotational movement.

• Compact and self-supporting design: With their integrated flange, these bearings can simplify mounting and reduce the installation space requirement, contributing to a compact equipment design.

• Rotation flexibility: Flange Slewing Bearings allow for continuous 360-degree rotation, making them suitable for applications with demanding rotational movement requirements.

• Customizable parameters: These bearings can be adapted in terms of size, gear configurations (internal, external, or gearless), and sealing solutions to suit specific application needs.

Application of Flange Slewing Bearings

Flange Slewing Bearings find applications in a wide range of industries, including but not limited to:

• Construction machinery: Used in equipment like excavators, cranes, and lift platforms, these bearings deliver the necessary rotation and load-bearing capacity.

• Wind turbines: In wind energy systems, Flange Slewing Bearings enable the yaw and pitch control necessary for optimizing energy production.

• Industrial turntables: These bearings facilitate smooth and accurate rotation for processing equipment, assembly lines, and manufacturing machines.

• Medical equipment: Flange Slewing Bearings can be found in medical devices like CT scanners and radiotherapy machines that require precise and consistent rotation.
