Komatsu PC200-5 excavator spare parts slewing bearing slewing circle slewing ring MODEL NO.PART NO.EC140CLVOE14520561EC140BLCV20400EC210SA1155-00061EC210B14563327EC210LC14563328EC210NLC EC240BLCSA115500040EC240BNLC14520572EC290 EC360 EC290BLC14563335EC360B14512787EC700VIN1013214559205 The single row crossed roller slewing bearing is composed of two seat rings, which design in compact structure and light weight, the clearance is small when assembly, so need high precision. The roller is 1:1 cross arranged, it can bear the axial force, tilting moment and relatively large radial force. It is widely used for hoisting, transportation, construction machinery, and the military products.Double row ball slewing bearing has two row rolling balls (with same size), which can bear big axial load, radial load and tilting moment. Safety factor is higher.It can used for different cranes, mining equipment, excavators etc.The three row roller bearing has three seat rings, which separate the upper, lower and radial raceways, it made each row of the roller’s load capacitycan be specified and can bear different loads simultaneously. The capacity load is the largest one compare with the other three models. Due to thelarge size in axial and radial dimension & the solid structure, it is especially suitable for the heavy duty machinery such as wheeled excavator, wheeled crane, ship crane, ladle turrets and the heavy duty mobile crane etc.The Thin Section Slewing Bearing has the same structure with the ordinary slewing bearing, but the weight is lighter, and rotates flexibly, which widelyused in the food machinery, canning machinery and environmental machinery etc. Three types of this kind of slewing bearing:A. Without gear bearingB. External gear bearingC. Internal gear bearing
