حلقه چرخان XZWD برای بیل مکانیکی جهت حفر تونل

The three row roller slewing bearing has three row raceway, the rolling element is steel roller. This structure could bear the heaviest load comparing to other structure bearing type. Usually the triple row roller slew bearing is used for some heavy duty machinery. Three-Row Roller Slewing Ring is equipped with seat-rings, upper orbit. Neither orbit and radial orbit is separated individually, it makes the load of each row of the rollers can be confirmed, making it can undertake all kinds of different load simultaneously. Three row roller slewing bearing's carrying capacity is the biggest among four models and the axial and radial size are rather large to some extent, the structure of the three row roller slewing bearing ring is very firm.

Three row roller slewing bearing is mainly made of 50Mn, 42CrMo, C45.

The triple row roller slew bearing has been widely used in many applications:
1. Wheeled excavator

2. Wheeled crane

3. Ship crane, offshore crane

4. Ladle turrets

5. Heavy duty mobile crane

It can be used for slewing conveyer, welding manipulator, light & medium duty crane, excavator, and other construction machinery.
