Types of Slewing Bearings

Single-Row Ball Slewing Bearings

These bearings feature a single row of balls designed to handle both radial and axial loads in applications where compact, lightweight design is critical. Single-row ball slewing bearings are ideal for small to medium-sized equipment such as cranes and excavators, where load distribution and ease of installation are paramount.

Double-Row Ball Slewing Bearings

Built with two rows of balls, these slewing bearings offer increased load capacity, handling both heavier axial and radial loads with high precision. Double-row ball slewing bearings are commonly used in applications requiring enhanced stability, such as large cranes, earth-moving equipment, and wind turbines.

Crossed-Roller Slewing Bearings

Crossed-roller slewing bearings provide excellent load-bearing capacity in all directions and are designed to deliver high rigidity and rotational accuracy. This makes them suitable for precision applications like robotics, medical equipment, and satellite antennas, where both stability and smooth motion are essential.

Three-Row Roller Slewing Bearings

These robust bearings consist of three rows of rollers, which independently support axial, radial, and tilting moment loads. This design provides exceptional load-carrying capacity and is typically used in heavy-duty applications like large excavators, offshore cranes, and ship loaders, where the heaviest loads and the most challenging conditions are encountered.

Design and Construction

Slewing bearings are constructed to withstand heavy loads and provide smooth rotation under pressure. Built with precision raceways and either ball or roller elements, these bearings are ideal for supporting radial, axial, and moment loads. The design often incorporates gear teeth for direct attachment, simplifying integration into equipment.

Available in a wide range of sizes and configurations, slewing bearings are manufactured to meet ISO and ANSI standards, ensuring compatibility across different systems. Their robust design and reliable construction make them suitable for high-load, slow-rotation applications, including crane swivels, excavator turntables, and wind turbines.
