Four Point Contact Ball Slewing Bearing Key Features

Four-Point Contact: The special raceway design enables the balls to contact both the inner and outer ring at four points, allowing the bearing to support high loads in all directions.

Compact Design: Single-row construction reduces weight and space requirements while maintaining high load capacity.

High Load Capacity: Can handle axial, radial, and tilting moment loads efficiently.

Low Friction & Smooth Rotation: Designed for stable movement with minimal resistance.

Easy Maintenance: Simple lubrication points and easy-to-install structure.

Structure & Components

Outer Ring: Stationary or rotating component with an integrated raceway.

Inner Ring: Supports the load and connects to the rotating part of the machine.

Rolling Elements (Balls): Typically made of high-quality steel for durability and smooth movement.

Cage or Spacer: Separates the balls and ensures even load distribution.

Seals & Lubrication Ports: Protect against contaminants and enable easy maintenance.

Applications

Four-point contact ball slewing bearings are widely used in various industries due to their ability to handle complex loads. Common applications include:

Cranes (tower cranes, mobile cranes, port cranes)

Excavators & Construction Equipment

Wind Turbines

Robotic Arms & Turntables

Medical Equipment (CT Scanners, MRI Machines)

Defense & Radar Systems

Advantages

Handles multiple load types (axial, radial, moment)

Compact and lightweight compared to other slewing bearings

Lower friction and longer service life with proper lubrication

Easy to install and replace
