Double Row Ball Slewing Bearing

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. Packing 1 Bearing surface is covered with the anti-rust oil first; and then wrapped with the plastic film; 2 And then packed with craft paper and professional belts; 3 At last, with wooden box totally at the outer packing to invoid the rust or the moist; 4 We can depend on the customers demand to be packed; 3. Features Larger dimension of axial and radial, compact structure. 4. Applications Tower cranes which require working radius over medium range, auto crane and loading (unloading) machinery. Bearing surface is covered with the anti-rust oil first; and then wrapped with the plastic film;and then packed with kraft paper and professional belts; at last, with wooden box totally at the outer packing to invoid the rust or the moist; we can depend on the customers demand to be packed.

The three-row roller slewing bearing consists of three races with its separated upper, lower and radial raceway, to certainly determine the loads of each row of rollers. It can take all kinds of loads simultaneously. It takes the heaviest loading one of the four kinds of products. It has larger axial and radial dimension and stable structure. It is especially used for the large-diameter heavy-duty machinery such as wheel excavator, all terrain cranes, harbor cranes, ladle rotating and big-ton truck-mounted cranes etc.
