High-precision slewing bearings for cranes & excavators. superior load capacity. Factory-direct pricing, custom designs, global shipping. Instant

As a leading manufacturer with years of expertise, we specialize in producing high-performance slewing bearings (also known as turntable bearings or slewing rings). Often referred to as the "joints of machinery," our products are engineered to facilitate smooth and reliable rotation between two objects while simultaneously withstanding significant axial forces, radial forces, and tilting moments.

We offer a comprehensive range of standard and custom-designed slewing bearings to meet the diverse needs of modern industry, all supplied directly from our factory to ensure the most competitive pricing.

• Superior Load Capacity: Our bearings are designed to handle complex, multi-directional loads, ensuring stability and durability in heavy-duty applications.
• Robust Construction: Manufactured from high-strength alloy steel and featuring precision heat treatment (e.g., medium-frequency quenching), our raceways achieve a hardness of HRC55-62 for exceptional wear resistance and a long service life.
• Compact & Efficient Design: The integrated design allows for a more compact host machine structure, simplifying design and maintenance. Options include integrated gears (internal or external) for direct drive applications.
• Low Friction & Smooth Operation: Precision-engineered rolling elements (balls or rollers) and high-quality seals ensure low starting torque and smooth, consistent rotation.
• Direct Factory Price: As a manufacturer, we eliminate intermediaries, providing you with top-quality products at the most cost-effective prices.

We produce a wide variety of slewing bearing types to suit different operational requirements:

1. Single-Row Four-Point Contact Ball Type (01 Series):

   • Compact and lightweight.
   • Handles axial, radial, and tilting moment loads simultaneously.
   • Ideal for welding manipulators,中小型 cranes, and excavators.

2. Double-Row Different-Diameter Ball Type (02 Series):

   • Features two rows of steel balls with different diameters for enhanced load capacity.
   • Suited for medium to large diameter applications like tower cranes and truck cranes.

3. Three-Row Roller Type:

   • Our highest load-capacity model.
   • Uses three rows of cylindrical rollers to separately absorb axial, radial, and tilting loads.
   • Perfect for the most demanding applications, such as large port cranes, ship-to-shore cranes, and heavy-duty construction machinery.

4. Crossed Roller Type:

   • Offers high rigidity and rotational accuracy.
   • Excellent for applications requiring precise movement, such as industrial robots and radar antennas.

Our slewing bearings are critical components in a vast array of machinery across multiple industries:

• Construction & Engineering Machinery: Excavators, mobile cranes, tower cranes, concrete pump trucks.
• Port & Shipbuilding Machinery: Port cranes, ship cranes, container handling equipment.
• New Energy: Wind turbine yaw and pitch systems, solar tracking systems.
• Industrial Equipment: Welding positioners, rotary tables, packaging machinery.
• Specialized Equipment: Radar systems, missile launchers, medical CT scanners, and even revolving restaurants.
