Description:
Three-row cylindrical cross roller slewing bearing has three seat-rings, which separate the upper, lower and radial raceway, via which the load of each row of the rollers may be specified. Thus it can carry different load simultaneously and its load capacity is the largest one of the four types. mainly made up of in-up ring, in-down ring and outside ring. Three rings are separated so each row roller loads can be confirmed exactly and they can bear axial force, resultant torque and considerable radial force at the same time. This series has the maximum load capacity of these four series.
Features:
Larger axial and radial dimension, compact structure.It features compact in design.
Application:
Especially used in heavy duty machines which require large working radius, such as
© Bucket-wheel excavators,
© wheeled cranes,
© Ship cranes
© Ladle turret
© Marine pedestal crane,
© Ladle slewing mechanism
© Large-tonnage mobile crane,
© Auto cranes
© Heavy duty mobile crane
