This series of slewing bearing is mainly made up of in-up rings,in-down rings and outside rings.The diameters of up-row and down-row bails are different; it is suitable for high precision mounting and capable to bear axial force, resultant torque and considerable large radial force. Its loading capabilities are better than single-row slewing rings.
The n1 means the number of lubricating holes, evenly distributed, lubricating nipple M10×1JB/T7940.1.
Gear force of periphery given in the table is its maximum value; nominal force of periphery is taken 1/2 of the given value.
