Single-row ball slewing bearing
Adopting an integrated internal gear structure, all transmission gears are built into the slewing bearing inner ring. This design does not occupy the narrow central hollow cavity of the sculpture, perfectly saving the space of hollow stacked art structures. Its compact slim profile matches our supporting split flange base precisely, forming a complete and stable rotary load-bearing system.
Features & Performance Advantages
Integrated internal gear space-saving design: the internal gear transmission structure integrates driving teeth inside the bearing ring, avoiding external gear protrusion. It greatly saves internal installation space and maintains the overall minimalist and artistic appearance of stacked metal sculptures without damaging the visual integrity of the installation.
Strong Load-Bearing & Anti-Overturning Performance: adopting a single-row four-point contact ball structure, the slewing bearing withstands heavy axial load, radial load and overturning moment. It effectively resists lateral wind force on high-rise stacked sculptures, preventing shaking and structural deformation during long-term outdoor operation.
