Slewing ring bearing with triple rows of rollers
Three-Row Cylindrical Roller Slewing Bearings
Request a Quote
Three-row cylindrical roller slewing bearings is built for applications requiring exceptional load-handling capabilities. With three rows of rollers, this bearing design ensures that the load is distributed across different rows, each dedicated to managing specific force such as axial loads, radial loads, and overturning moments. This configuration provides superior rigidity and stability during rotation, making it highly effective for heavy-duty and complex load scenarios. However, due to its design, it requires precise installation and is more sensitive to any deformations in the mounting structure.
These bearings are typically manufactured using 42CrMo4 steel with induction-hardened raceways to maximize durability. However, depending on the application and customer needs, other materials can be selected to suit specific operational environments.
Manufacturing Capability
LYXQL has advanced capabilities in producing Three-row cylindrical roller slewing bearings, tailored to meet demanding industrial requirements. We can manufacture integrated structure bearings with a maximum outer diameter of 12 meters, while for split structures, the maximum outer diameter reaches up to 20 meters.
The gear module size can go up to 45mm, accommodating a wide range of design needs.
(We offer customization options to create non-standard products based on specific user requirements)
Options of Slewing Bearings
Our three-row cylindrical roller slewing bearings are designed to be versatile, available in three distinct configurations: external gear, internal gear, and gearless designs. Each option is built with a robust structure that includes inner and outer rings, rollers, spacers (bearing cages), and seals. To further enhance durability, especially in challenging environments, we offer additional dust-proofing features like dust covers or ash shields based on specific application requirements.
This design features gear teeth on the outer ring. Due to the external location of the gear mesh, this configuration generally requires more installation space compared to internal gear designs. It is ideal for applications where external gear interaction is necessary and where space constraints are not a primary concern.
In this configuration, the gear teeth are located on the inner ring, allowing the gear mesh to occur inside the bearing. This design is more space-efficient than the external gear option, making it suitable for applications where installation space is limited.
This gearless design features smooth inner and outer rings with no gear teeth, making it suitable for applications where gear interaction is not needed. This simple design offers ease of maintenance and can be used in systems where simplicity and reliability are key.
