Consists of a thrust/centering collar, a thrust/centering shaft collar, a thrust washer, two needle cage assemblies and a set of centering cylindrical rollers. The housing locating washer and shaft locating washer have evenly spaced screw holes for mounting. This type of bearing has a high axial and radial load carrying capacity. High tilting rigidity and high accuracy. They are suitable for use in rotary tables, chucks and iron bits as well as in measuring and experimental bearing arrangements. These bearings also place high demands on the machine parts to which they must be fitted. The torque of the mounting screws must be controlled during mounting.
