Product description:
1. This series of bearings have three rows of independent rollers, whose normal direction is consistent with bearing bearing bearing direction.Such a configuration can make the bearing capacity, friction resistance reduced.The upper and lower rows of rollers can not only bear the two-way thrust load, but also bear the torque load together when the middle row of rollers bear the radial force.

2. Three-row roller slewing bearing is mainly composed of inner upper ring, inner lower ring and outer ring. It has reasonable design, high working accuracy and large bearing load, and can bear the combined action of axial force, radial force and overturning moment at the same time.

3. This system is listed as a series of cost performance in the operating condition of heavy machinery.

4. The three row roller slewing bearing has three seat, and the radial raceway separate from top to bottom, to make each row roller negative load can be exactly determined, can simultaneously under various load, is one of the four products bearing capacity, axial radial size is large, firm structure, the series of roller bearing with three columns independent, its normal direction and bearing load in the same direction.

Three row roller slewing bearing application:
heavy excavator, crane, port crane, shield machine (tunneling machine), unloading machine, ladle rotary table, stacking machine and other mechanical equipment fields.

Combined rotary disc bearing with three rows of cylindrical rollers
