Series 11 Slewing Bearings--Single Row Crossed Roller Type

Single row crossed roller slewing bearings, is composed of two rings, compact structure, light weight, high manufacturing precision, small assembly clearance, high requirements for installation accuracy, the rollers for the 1:1 cross-arrangement, can simultaneously withstand the axial force, tilting moment and large radial force, is widely used in lifting and transportation, engineering machinery and military products. This type of bearing pre-surplus has high rotary accuracy, support rigidity and the ability to withstand high dynamic loads.

Series 13 Slewing Bearings--Three Row Roller Type

Three row roller slewing bearings have three rings, upper, lower and radial raceways are separated, so that each row of rollers respectively to bear the shaft, radial load, is the largest of the four products in the bearing capacity of a shaft, radial size are larger, but the relative diameter of the bearings is greatly reduced in size, with a host of supporting the structure of the characteristics of the compact. Particularly suitable for heavy machinery requiring large loads, such as bucket wheel excavators, wheeled cranes, marine cranes, harbor cranes, steel running table and large tonnage truck cranes and other machinery.
