Our Slewing Bearings, also known as turntable bearings or rotary supports, are precision-engineered components designed to be the "joints of machinery." They are built to handle complex, multi-directional forces, making them indispensable for any application requiring slow, heavy-duty rotation. We offer a comprehensive range of standard and custom-designed slewing bearings to meet the diverse needs of modern industry.
Key Features & Advantages
Superior Load Capacity: Engineered to simultaneously withstand heavy axial, radial, and tilting moment loads, ensuring stability and reliability under extreme operating conditions.
Compact & Integrated Design: Our bearings integrate the functions of a support structure and a rotation mechanism into a single, space-saving component. This simplifies host machine design and reduces overall weight.
Versatile Configurations: Available with internal or external gear teeth for direct drive integration, or as plain rings. Various mounting hole patterns and sealing options are offered to suit specific application requirements.
Robust Construction & Long Life: Manufactured from high-strength alloy steel and subjected to advanced heat treatment processes, our bearings feature hardened raceways for exceptional wear resistance and extended service life.
Low Maintenance: Equipped with high-quality seals and lubrication points, our slewing bearings are designed for smooth operation with minimal maintenance, reducing downtime and operational costs.
Product Range
We specialize in the design and production of a wide variety of slewing bearing series:
Single-Row Four-Point Contact Ball Series (01 Series): A compact and lightweight solution capable of handling combined loads. Ideal for中小型 cranes, excavators, and welding manipulators.
Double-Row Ball Series (02 Series): Features two rows of steel balls for higher load capacity and rigidity. Perfect for medium to large tower cranes, truck cranes, and other heavy-duty material handling equipment.
Three-Row Roller Series (13 Series): The ultimate choice for extreme load applications. This design uses three rows of rollers to separately handle axial and radial loads, offering the highest load-bearing capacity in a relatively compact size. Commonly used in large port cranes, offshore equipment, and heavy-duty excavators.
Crossed Roller Series (11 Series): Utilizes cylindrical rollers arranged at a 90° angle to each other, providing high rotational accuracy and rigidity. Suitable for applications requiring precise positioning, such as robotics and high-precision turntables.
Applications
Our slewing bearings are widely used across numerous industries, including:
Construction & Earthmoving Machinery: Excavators, cranes (mobile, tower, crawler), concrete pumps, and drilling rigs.
Port & Material Handling: Ship-to-shore cranes, rubber-tired gantry cranes (RTGs), and stacker-reclaimers.
Renewable Energy: Pitch and yaw systems for wind turbines.
Industrial & Manufacturing: Welding positioners, robotic arms, and rotary tables.
Other Specialized Equipment: Radar antennas, satellite dishes, and medical imaging systems (e.g., CT scanners).
