They are designed to support heavy loads and enable precise rotation, making them indispensable in various industries. This technical article delves into the engineering aspects, market trends, and applications of slewing bearings.

Engineering Aspects of Slewing Bearings

Slewing bearings

Slewing bearings are engineered to handle significant loads while maintaining rotational accuracy. They consist of an inner ring and an outer ring, with one usually incorporating a gear. The rings are designed with attachment holes for optimized power transmission and simple, quick connections between adjacent machine components. The bearing raceways, in conjunction with rolling elements and cages or spacers, are designed to accommodate loads acting singly or in combination, and in any direction.

Structural Optimization

The structural parameters of slewing bearings, such as ball diameter and the number of balls, are optimized for maximum carrying capacity and service life. Numerical methods based on static bearing capacity and fatigue life are used to optimize these parameters. Finite element models and local finite element models of the slewing bearing are established to analyze the carrying capacity of different structural parameters. The Hertz contact theory and experiments are used to compare the theoretically calculated load distribution, contact stress, contact area, and deformation.

Materials and Manufacturing

High-quality steel and advanced heat treatment processes are used in the manufacturing of slewing bearings. This provides a superior balance between hardness and toughness, enabling longer service life. The manufacturing processes are globally certified to ISO 14001 for environmental management, and OHSAS 18001 for health and safety management standards.

How to select slewing bearing

A slewing bearing is a specialized type of bearing that allows for rotational or slewing movement, typically used in heavy machinery. It consists of an inner ring and an outer ring, with rolling elements (like balls or rollers) between them. Unlike traditional bearings, slewing bearings are designed to handle both axial (up-and-down), radial (side-to-side), and moment (tilting) loads simultaneously.

Selecting a slewing bearing requires careful consideration of the application, load requirements, and environmental factors. Here’s a step-by-step guide to help you choose the right slewing bearing:

Slewing Bearing Selection
