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.

Our company specializes in six types of slewing bearings, including single-row ball type slewing bearing, double-row ball type slewing bearing, three-row roller type slewing bearing, single-row cross roller type slewing bearing, double-line ball type slewing bearing, ball-roller combined type slewing bearing. These deep groove radial bearings are used for heavy radial loads and relatively low bidirectional thrust loads. Typically employed in high-speed precision applications, deep groove radial ball bearings can be designed with enhanced metal shields or rubber seals. Multiple internal clearances, tolerance grades, and cages designs are offered to suit specific applications' running precision and speed.

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.
