ISB Italy Slewing Bearings

Product Description

Slewing Bearings are large-diameter, high-performance rotational bearings designed to support heavy loads while allowing smooth rotational movement. They are widely used in applications such as cranes, excavators, wind turbines, robotics, and industrial turntables, where the combination of axial, radial, and moment loads needs to be managed simultaneously. Their robust design makes them ideal for handling extreme loads while maintaining precision and reliability.

A typical slewing bearing consists of an inner ring, an outer ring, rolling elements (balls or rollers), and a sealing system to protect against dust and moisture. Depending on the application, slewing bearings may be configured as single-row or double-row ball bearings, or as crossed roller bearings. Single-row ball bearings are ideal for moderate load applications with high-speed rotation, while crossed roller bearings offer superior rigidity and load capacity, making them suitable for heavy-duty or high-precision applications.

Slewing bearings are manufactured with high-grade alloy steels and undergo advanced heat treatment processes to ensure strength, wear resistance, and long service life. They can be designed with integrated features such as internal or external gears, lubrication channels, and preloaded assemblies to enhance performance and reduce maintenance.

Key advantages of slewing bearings include their ability to handle combined loads, provide smooth rotation under heavy weight, and maintain structural stability in demanding conditions. With proper selection and maintenance, slewing bearings offer long-lasting, reliable performance in industries requiring precise, rotational motion of large components.
