LYXQL can produce many different constructers of slewing ring bearings, including single row ball slewing bearings (also called four point contact ball slewing bearings), double row ball slewing bearings (including same ball diameter double row ball slewing bearings and different ball diameter double row ball slewing bearings), crossed roller slewing bearings, three row roller slewing bearings and ball and roller combined slewing bearings.
Among of these slewing ring bearings, ball and roller combined slewing bearing is a special bearing, which has both ball and roller rolling elements.
The materials of the inner and outer rings and rolling elements of the ball and roller combined slewing bearings without teeth generally meet two requirements:
1. The mechanical properties of the slewing bearing material must meet the requirements that the raceway surface must have strong contact strength, wear resistance and erosion resistance. The tooth part of the ring gear must have high gear tooth strength, impact toughness and wear resistance.
2. The heat treatment process performance of the slewing bearing material should meet the requirements. The material should have good hardened ability and proper hardened ability. The raceway surface quenching, gear ring quenching and tempering, and tooth surface quenching are to improve the quality of the slewing ring and prolong the service life of the slewing ring.
The material of the rolling element of the slewing ring is generally the whole hardened high carbon chromium bearing steel GCr15 or GCr15SiMn.
The inner and outer rings of the bearing are made of surface-hardened 50Mn or 42CrMo.
Ball and roller combined slewing bearings without teeth are widely used in engineering, mining, metallurgy, shipbuilding, ports, petroleum, chemical, food, aerospace and other industries
Ball and roller combined slewing bearings can be produced with different gears, with external gears, with internal gears and without gears.
