Eight-Point Contact Different Path Slewing Ring Bearings

Eight-Point Contact Different Path Slewing Ring Bearings, also known as Double Row Different Diameter Ball Slewing Bearings, have three seating rings, steel balls and isolation blocks can be directly discharged into the upper and lower seating rings. According to the stress conditions, two rows of steel balls with different diameters are arranged. It can withstand axial force and radial force at the same time.

Double rows of reducer ball slewing bearing usually consists of inner ring, outer ring, rolling elements and spacer block four parts, can withstand axial, tilting moment and radial load at the same time, the upper row of balls mainly to withstand axial and tilting moment, the lower row of balls mainly to withstand the reverse tilting moment, so double rows of reducer ball slewing bearing bearing load carrying capacity than the four-point contact ball bearings, but its frictional resistance is larger than the latter. The contact angle of double-row radial ball slewing bearings can be adjusted to cope with different combinations of axial force, tilting moment and radial force under various working conditions. The inner or outer ring of double-row radial ball slewing bearings is divided into whole and split structure, which can bear axial force and radial force at the same time due to the adoption of slewing bearings as the core component.
