Inner Ring Toothed Three Row Cylindrical Roller Slewing Bearing

The three-row cylindrical roller slew bearing with toothed inner ring is the core supporting component in the field of heavy-duty machinery. It consists of an inner ring with an inner ring gear, an outer ring and three rows of independent cylindrical rollers. It integrates super load-bearing and direct power transmission functions. It has a compact structure and is adaptable to complex working conditions. Its core advantages are reflected in two points: First, three rows of rollers are divided into load-bearing units. Two rows of axial rollers are dedicated to bear bidirectional axial loads, and one row of radial rollers bear radial loads. The line contact design evenly distributes the load, and can effectively withstand huge axial force, radial force and tilt. The overturning moment and load-bearing capacity are much better than those of single-row or double-row structures; secondly, the inner ring gear transmission**, the precision ring gear processed in the inner ring can directly m…
