Three row roller slewing ring (13 series) - internal gear type
Structural features, performance and scope of application
The three row roller slewing ring has three seat rings, and the upper, lower and radial raceways are separated respectively, so that the load of each row of rollers can be determined accurately. The three row roller slewing ring can bear various loads at the same time. The three row roller slewing ring is the one with the largest bearing capacity among the four products. The shaft and radial dimensions are large and the structure is firm. The three row roller slewing ring is especially suitable for heavy machinery requiring large diameter, such as bucket wheel excavator, wheel crane, marine crane, port crane, steel water transportation turntable and large tonnage truck crane.
The basic rated dynamic load of The three row roller slewing ring radial bearing and thrust bearing is also called radial basic rated dynamic load and axial basic rated dynamic load.
The rotary table bearing with The three row roller slewing ring， high temperature resistance also includes high-temperature operation machinery such as metallurgy, kiln, glass, blast furnace and painting equipment. The difference between high-temperature bearing and slewing ring ordinary bearing is mainly reflected in the following two aspects: the parts of the bearing are made of bearing steel and tempered at high temperature, and then they need to be selected according to the method specified in code JB / t2974; The parts and components of The three row roller slewing ring ，the bearing are made of heat-resistant steel. According to the provisions of JB / t2974, the post code is Cr4Mo4V, the post code is / HN, the material used is cr14mo4, and the post code is / HN1, the material of slewing ring is cr15mo4v.
