Larger size double row ball slewing bearing exported to South korea
This month we ship the big size double row ball slewing bearing to Korea
This double row ball bearing have three seal ring ,The steel ball and isolators can be directly arranged into the upper and lower raceways .
Double-row ball slewing bearing can carry axial load, tilting moment and radial loads at the same time. The top ball mainly carries the axial load and positive tilting moment. The drop ball takes the opposite tilting moment. This is the reason for the loading capacity of the double row ball slewing bearing being larger than the four-point contact ball slewing bearing; however, the frictional ratio is much larger. than the latter.
