As a professional triple row cylindrical roller combined slewing bearing manufacturer in China, we mainly provide internal gear type triple row cylindrical roller combined slewing bearings, external gear type triple row cylindrical roller combined slewing bearings and no gear type triple row cylindrical roller combined slewing bearings. Characteristics of Triple Row Cylindrical Roller Combined Slewing Bearing 1. Our triple row cylindrical roller combined slewing bearing has super high carrying capacity. 2. It consists of three bearing rings. The adjusting spacer between upper bearing ring and lower bearing ring can adjust the axial internal clearance. 3. Upper row rollers and lower row rollers are distributed horizontally, so as to support the axial forces and tilting moments from two directions. While radial force is supported by the third row rollers that are vertically distributed. 4. Since our triple row cylindrical roller combined slewing bearing is firm in structure and large in axial dimension and radial dimension, it is quite suitable for use in heavy duty machinery, such as bucket-wheel excavators, wheel cranes, ship cranes, port cranes, molten steel operating platforms, and so on. I am pleased to recommend our company and its bearings. Our company was set up in 1998, specialized in the design and production of slewing bearings. We began to export in 2003, users have covered scores of countries. Sales and market has been steadily growing in the passed years.
