Enhancing Efficiency and Stability: Exploring Double Row Ball Slewing Bearings

In industries that require heavy machinery and rotating structures, the importance of reliable and efficient bearings cannot be overstated. Double row ball slewing bearings are specially designed components that facilitate smooth and controlled rotation in various applications. These bearings offer exceptional load-carrying capacity, precise positioning, and durability, making them a popular choice for demanding industrial environments. In this blog post, we will delve into the world of double row ball slewing bearings, their design principles, advantages, and diverse applications across industries.

Understanding Double Row Ball Slewing Bearings:

Double row ball slewing bearings are precision-engineered components designed to support axial, radial, and moment loads while enabling rotational movement. These bearings consist of an inner ring, an outer ring, a set of steel balls, and a cage that maintains the ball spacing and allows smooth rotation. They are primarily used in applications that require high load capacities and precise positioning, such as cranes, excavators, wind turbines, and turntables.

Advantages of Double Row Ball Slewing Bearings:

Load-Carrying Capacity: Double row ball slewing bearings are designed to withstand heavy axial, radial, and moment loads. Their robust construction and optimized ball configuration enable them to handle high load capacities, providing stability and durability in demanding applications.

Precise Positioning: With their exceptional rotational precision, double row ball slewing bearings ensure accurate positioning of rotating structures. This is crucial in applications such as construction machinery, where precise movement and alignment are necessary for efficient operation.

Compact Design: Double row ball slewing bearings offer a compact design, allowing for efficient use of space in equipment and machinery. Their high load-carrying capacity and compactness make them an ideal choice in situations where size and weight limitations exist.

Durability and Longevity: Manufactured using high-quality materials and advanced engineering techniques, double row ball slewing bearings are built to withstand harsh operating conditions, extreme temperatures, and heavy loads. Their robust construction ensures longevity and minimizes downtime due to bearing failures.

Applications of Double Row Ball Slewing Bearings:

Double row ball slewing bearings find applications across a wide range of industries:

Material Handling and Cranes: These bearings are extensively used in cranes, excavators, and material handling equipment. They provide smooth rotation, precise positioning, and high load capacity, enabling efficient lifting, loading, and material transfer operations.

Wind Energy: In wind turbines, double row ball slewing bearings play a vital role in supporting the rotation of the turbine blades. They ensure smooth and controlled movement, allowing optimal wind capture and energy generation.

Turntables and Rotating Platforms: Double row ball slewing bearings are commonly employed in turntables and rotating platforms used in industries such as entertainment, logistics, and transportation. They enable smooth and reliable rotation, facilitating efficient loading, unloading, and positioning of goods or equipment.

Mining and Heavy Equipment: In mining and heavy machinery, double row ball slewing bearings provide stability and durability for applications such as excavators, crushers, and conveyor systems. They withstand the high loads and harsh operating conditions commonly encountered in these industries.

This type of slewing ring bearing is generally chosen where there are heavy loads as compared to single row bearing.  The ball size for this type of bearing varies from 30mm to 50mm.By using proper software and research, the ball size is chosen, which ensures proper selection of axial load and torque. The material selection is done based on the input parameters and the requirement of the customer. The material that is used in this type is generally 42CrMO or C45.  Sometimes, for boom cranes and tower cranes, the material required is 50Mn.  The balls are made of High chromium steel, generally denoted by 100Cr6 and the cages are made of either nylon 6 or nylon 66 depending on the load conditions. Such type of slewing ring bearing are usually used where the static load is high and the installation space is limited. The applications for such types of slew ring bearings are:
