What Is a Flanged Slewing Bearing?

What Is a Flanged Slewing Bearing?

flanged slewing bearing is a special type of slewing bearing designed with an integrated flange on the inner or outer ring. This flange simplifies installation and provides a secure connection to the mounting surface. As one of the most compact and versatile bearing types, flanged slewing bearings are ideal for equipment that requires both rotational accuracy and limited installation space.

Unlike traditional ball or roller bearings, flanged slewing bearings can support axial loads, radial loads, and tilting moments simultaneously, making them a preferred solution in modern machinery where stability and precision are essential.

Design Structure

The structure of a flanged slewing bearing usually includes an inner ring, outer ring with flange, rolling elements (balls or rollers), spacers, and seals.

• Flanged outer ring: Enables easier positioning and assembly.

• Rolling elements: Provide smooth rotation and reduce friction.

• Sealing system: Prevents dust, moisture, and contaminants from entering, ensuring long service life.

This integrated design reduces the need for separate mounting components and enhances installation efficiency — an advantage recognized by many slewing bearing manufacturers worldwide.

Features and Advantages

Flanged slewing bearings offer multiple benefits that make them suitable for demanding industrial use:

• Compact design – Ideal for equipment with limited installation space.

• Easy installation – The flange provides direct mounting without additional plates.

• High reliability – Designed for continuous operation under heavy loads.

• Precision performance – Ensures smooth rotation and reduced vibration.

• Cost efficiency – Fewer components mean lower maintenance and a competitive slewing bearing price.

Applications of Flanged Slewing Bearings

Flanged slewing bearings are widely used in various slewing bearing applications, including:

• Construction machinery such as cranes, excavators, and concrete pumps.

• Industrial automation systems and robotic arms.

• Medical and precision equipment requiring compact rotation mechanisms.

• Renewable energy systems such as solar trackers and small wind turbines.

• Marine and defense systems that demand high corrosion resistance and reliability.

Their versatility and load-carrying capacity make flanged slewing bearings a critical part of many modern engineering solutions.

What is the difference between flange bearings and slewing bearings?

While both types belong to the slewing bearing family, their main difference lies in the mounting structure.

• Flanged slewing bearing: Features an integrated flange that simplifies installation and saves space.

• Standard slewing bearing (turntable bearing): Typically requires external bolts or housing to fix the bearing in place.

In short, flanged slewing bearings provide a more compact and user-friendly option for equipment where space and weight are limited, while standard slewing bearings are preferred for larger, heavy-duty machines.
