SLEWING RING BEARING
The slewing bearings with flanges on the outer wheel make axial positioning simple. The bearing housing is no longer needed, and it becomes more economical. The flanged slewing bearing mainly bears radial force, but it can also bear radial force and axial force at the same time.
The four-point contact ball slewing bearing is a separable bearing, which can bear radial load and bidirectional axial load, and consists of two rings,The steel ball is in four-point contact with the raceway, with compact structure and light weight.
Crossed roller slewing bearing require high installation accuracy and consist of two rings, With compact structure, light weight, high manufacturing precision, small assembly clearance, can bear axial force, large radial force and overturning moment at the same time.
There are two rows of steel balls on the upper and lower sides of the double-row ball bearing, which can bear radial force, axial force and overturning moment at the same time. It is widely used in heavy transport machinery, port machinery, mining machinery, filling machines and other large slewing devices.
The three-row cylindrical roller combination slewing bearing has large shaft and radial dimensions, and has three separate raceways for the upper and lower raceways and the radial raceway, which can bear various loads at the same time, with large bearing capacity and firm structure.
Double row roller slewing ring bearing
Ball and roller combination slewing ring is designed to accommodate axial, radial, and tilting moment loads acting singly or in combination. This kind of slewing ring bearing features long lifespan and large outer diameter and mainly used in applications where eccentricity ratio e(e=2 xMx 1000/Fa x Dpw) is smaller than 1.2.
