Heavy duty lazy susan bearing is a kind of large bearing with special structure, which can bear large axial load, radial load and overturning moment at the same time, and integrates support, rotation, transmission, fixing and other functions in one.
Heavy duty lazy susan bearings are usually composed of four parts, such as inner ring, outer ring, rolling body and isolation block, which can withstand axial force and radial force.Heavy duty lazy susan bearing forms are varied, but the structure is basically the same. The upper part includes an outer ring, a sealing belt, a rolling body and a refueling nozzle, and the lower part includes a plug, a taper pin, an inner ring, an isolation block or cage and a mounting hole.

Single-row cross-roller type heavy duty lazy susan bearings, consisting of two racings, offer compact construction, lightweight characteristics and high manufacturing accuracy. The assembly gap is small and the installation accuracy is high. The rollers are arranged 1:1, which can withstand axial force, tipping moment and large radial force at the same time. Therefore, the bearing has been widely used in the fields of lifting and transportation, construction machinery and military industry.
