Three Row Roller Slewing Bearing
- Three-row roller bearings with slewing are essential for heavy machinery, known for handling high loads with exceptional stability. Their design efficiently manages axial, radial, and moment loads for reliable performance.
- The compact structure maximizes space efficiency, making them ideal for applications requiring strength and durability. Their versatility and customization options cater to diverse industry needs.
- Widely used in construction, energy, and material handling, these bearings provide robust and reliable support, essential for modern heavy-duty applications.
Three-row slewing roller bearings deliver outstanding performance in mechanical systems that are high-precision and heavy-loaded. The bearings feature a three-row design that provides a greater support surface than a double-row arrangement. This allows for greater load-bearing capability.
Structural features and performance:
The three-row bearing is designed to accommodate axial and rotational loads on each row of rollers. This is one of four products that have the highest carrying capacity. It’s ideal for heavy machinery.
Materials and Construction:
These bearings have an outer diameter ranging from 634mm up to 5282mm. The roller diameters vary from 25mm up to 50mm. These bearings are rated for loads ranging from 275kN up to 6050kN. The rings are typically made of 42CrMo or 50Mn while the rollers consist of GCr15. The cage is made from cast aluminum alloy ZL102 or steel 20. Spacers are nylon 6 or nylon66. The raceway is HRC55 to 62 hard, which ensures durability and reliability.
Applications:
The bearings can be found in many applications including wheel excavators and wheel cranes. They are also used on molten steel tables, port cranes and marine cranes. These bearings are ideal for heavy equipment that is subjected to significant axial and/or radial loads.
Product Advantages
Extremely high load-bearing capacity:
- The 3-row design provides a large support area and is suitable for very heavy equipment.
Excellent stability:
- The distribution three rows of rollers increases stability and provides reliable performance even in environments with high precision or heavy loads.
Compact design:
- By distributing the loads on different rows, bearing diameters are reduced. This makes the slewing rings more compact, and improves load capacity.
Customization and Services
we could provide OEM customized services to ensure that these bearings are tailored to the specific requirements of a project. These bearings come in a variety of standard and customized models to suit the needs of different industries.
