Three-Row Cylindrical Roller Slewing Bearing - Heavy-Duty Load Bearing Solutions
When you're dealing with heavy equipment that demands exceptional load-bearing capacity, the Three-Row Cylindrical Roller Slewing Bearing stands as your ultimate solution. This innovative bearing design features three independent rows of cylindrical rollers that expertly distribute axial forces, radial loads, and overturning moments across your machinery. Unlike traditional bearing designs, this advanced system transforms point contact into line contact, dramatically reducing stress concentrations while maximizing load capacity. You'll discover that this bearing type offers the highest load-bearing performance among all slewing bearing categories when comparing identical outer dimensions.
Superior Engineering Design
The three-row configuration creates a perfect division of labor within your bearing system. Two horizontal roller rows handle axial loads and overturning moments, while the vertical row manages radial forces. This intelligent load distribution means each roller experiences reduced stress compared to alternative designs.
Your bearing consists of precision-engineered inner and outer rings, three distinct roller rows, specialized cages or isolation blocks, and advanced sealing systems. You can choose from no gear, external gear, or internal gear configurations based on your specific application requirements.
Premium Materials and Manufacturing
At Luoyang Heng Guan Bearing Technology, we craft your bearings using 42CrMo and 50Mn special alloy steel for base materials. The rolling elements utilize GCr15SiMn high-purity bearing steel, ensuring exceptional durability under extreme conditions.
Our cage options include brass, steel, or engineering plastic materials. You'll benefit from imported nitrile rubber or fluororubber sealing materials that provide superior protection against contamination.
Comprehensive Size Range
We manufacture Three-Row Cylindrical Roller Slewing Bearing units with inner diameters ranging from 500mm to 8000mm. Outer diameters span 600mm to 10000mm, with heights between 100mm and 500mm. Need something larger? We gladly accommodate custom extra-large sizes for your unique projects.
