External Geared Crossed Roller Slewing Bearings

As precision transmission components, the core structure of external geared slewing bearings typically consists of four key functional units: inner ring, outer ring, rolling elements, and separators. Designed based on slewing bearing technology, these bearings possess a combined load-bearing capacity for both axial and radial loads. Notably, despite the existence of multiple subtypes of cross-roller slewing bearings, their fundamental structural designs maintain a high degree of consistency—for example, the single-row cross-roller type features a dual-ring frame structure. Through precision machining, it achieves advantages of compact structure and lightweight design, while leveraging high-precision manufacturing processes to simultaneously bear multiple mechanical loads such as axial loads, overturning moments, and large radial loads. Additionally, this type of bearing supports the selection and configuration of internal or external gear rings according to specific operational requirements, exhibiting prominent advantages in installation adaptability and operational convenience. Currently, cross-roller slewing bearings are widely used in high-end equipment fields such as hoisting machinery, transportation equipment, and construction machinery.
