The three-row roller large slewing bearing is a high-performance bearing product designed to withstand large oil loads, overturning moments and radial loads. Its processing technology is complex but sophisticated, usually including material selection, forging, heat treatment, finishing and surface mounting.
Product detial
1. High-strength alloy steel such as 42CMo, 5sOMn, etc. are often used in materials. After quenching and tempering, the hardness can reach 170HB~340HB, ensuring the bearing's load capacity and wear resistance.
2. In terms of processing technology, in order to improve processing accuracy and reduce stress, segmented and faceted quenching technology is often used, and the geometric accuracy of the bearing is ensured through the shaping process. In addition, special molds are also used for assembly to improve assembly accuracy.
3. Three-row roller large slewing bearings are widely used in many fields due to their excellent load-bearing capacity and stability.
(1) In heavy machinery equipment such as ports and mines, such as bucket wheel excavators, shield machines, port cranes, etc., it is a key component to ensure the normal operation of the equipment.
(2) In the field of wind power generation, this bearing is also commonly used in the gearbox and wind turbine blades of wind turbines, playing an important role in the effective conversion and utilization of wind energy.
(3) In the fields of aerospace, transportation, etc., three-row roller large slewing bearings also show their unique advantages and value.
