Our different diameter ball slewing bearing has three seats ring,the steel balls and the spaces may be directly arranged into upper and lower raceways.two rows of steel balls with different diameters are fitted according to the load.such open mode fiting features are very convenience.the load angles of both upper and lower race are90,which enable the bearingto bear large axial froce and the overturning moment.when the radial force is larger than1/10 of the axial force .the raceways should be especial designed. the axial
The double-row ball slewing bearing The double-row ball slewing bearing has three races. The balls and cages can be directly aligned into the upper or lower raceway. According to force situation, the arrangement is two rows of different diameter balls. This kind of openly assembling is very handy. The loading angles of upper and lower raceways both are 90o. It can take large axial force, and overturning moment. When the radial force is larger than 0.1 times the axial force, its raceway must be designed specially. The double-row ball slewing bearing features bigger axial and radial dimensions, and stable structure. It is especially used for tower cranes with mid-diameter or bigger, and truck-mounted cranes etc loading machinery.
Double-row ball slewing bearing (02 series) 1. Description : The two-row ball slewing bearing has three seat-rings. The steel balls and the retainers may be directly arranged into the upper and lower racers. Two rows of steel balls with different diameters are fitted according to the force. Such open type fitting is extraordinary convenient, the loading angels at upper and lower races are 90 which can carry both of the axial force and capsizing moment. When the radial force is larger than 1/10 of the axial force, the races should be newly designed. 2.

Double row different diameter ball slewing bearing is mainly made up of in-up ring, in-down ring and outside ring, so balls and spacers can be directly discharged into the upper and lower raceway. According to stress conditions, bearings are arranged to two rows of balls of different diameter. This assembly is very convenient. Angle of both upper and lower raceway is 90�°so bearings can bear large axial force and resultant torque. Bearing needs special design when radial force is 0.1 times larger than the axial force. Large in sizes and features compact in design, bearings are particularly application in handling equipments requiring medium above diameter, such as tower crane and mobile crane. Three types of this kind of double row different diameter ball slewing bearings:

Slewing bearing can simultaneously support larger combined load including axial load, radial load and tilting moment etc. General slewing bearing all has mounting holes, oil holes and sealing apparatus, can meet categories of main machine operating under various different conditions. In addition, slewing bearing possess the characteristics of compact structure, guiding rotation convenient, easy installation and easy to maintenance, and widely applied to large size slewing equipment in the industries of engineering, mining, metallurgy, wind power generation, vessel, seaport, petroleum, chemical industry, light industry, medical appliance, foodstuff, vehicle, robot, aerospace, radar and war industry etc. According to different structural style, slewing bearing can be divided into four point contact ball slewing bearing, cross cylindrical (taper) roller slewing bearing, double row four point ball slewing bearing, double row different diameter ball slewing bearing, ball and roller combined slewing bearing and tri-row cylindrical roller combined slewing bearing etc. Above mentioned slewing bearings can also be divided into different structures of no gear type, external gear type and internal gear type as per if exist gear and gear teeth distributing position. According to different structural feature, slewing bearing can respectively meet main machine requirements under various load conditions. Among them, four point contact ball slewing bearing has higher dynamic load capacity, cross cylindrical roller slewing bearing has higher static load capacity. Tri-row cylindrical roller combined slewing bearing is a kind of high carrying capacity slewing bearing, due to leading raised carrying capacity to direction of bearing height, various loads can be respectively supported by different raceways and roller sets, so raceway diameter greatly decrease under the same stress condition, it has the character of making main machine more compact.
