Three Row Roller Slewing Bearing
Three-row roller slewing bearing decreases the bearing diameter by distributing the loads in different directions to different rows of raceways and rollers, which makes the slewing ring more compact and improves the load capacity. Three-row roller slewing ring is ideal for lifting, mining, material transportation, marine, and other engineering machinery.
