THB combined roller bearings include full complement cylindrical track roller set bearing radial load and full complement rolling needle set bearing axial load, forming radial and axial roller structures with different functions at different parts. Therefore, such bearings have small volumes and could bear combined radial and axial loads. In addition, various standardized flanges tracks could be provided to facilitate the clients to choose and install. The solid tracks are applicable to high dynamic and static loads. The carrying load could be distributed uniformly on the tracks. The combined roller bearings and tracks have long service lives and could be installed with welding bolt sets, ensuring the economical operation and easy replacement of the bearing components.
