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.

High quality ball slewing bearings Composed of rolling elements maintaining separation between the inner and outer rings of a bearing, ball bearings allow for smooth, high-speed motion and reduced friction. Able to sustain both radial and axial loads, they can be developed for many different applications, load types, and speeds. Xuzhou Fenghe Intelligent Technology Co., Ltd. specializes in six types slewing bearings, including single-row ball type, double-row ball type, three-row roller type, single-row cross roller type, double-line ball type and ball-roller combined type. Ball bearings are usually made of stainless steel, ceramic, or chrome steel, but material and overall design can vary widely depending on the specific job at hand. Flange, cages, and multiple bearing rows can also be included to allow for higher performance in order to meet specific application needs.

Slewing bearings are extensively applied in such industries as metallurgy, vessel, oil, chemistry, mine, coal, hydroelectric power, port machinery, heavy machinery and aerospace or some other fields. Regular application areas: Mine machine, port hoisting machine, port oil transfer equipment, onshore and offshore crane, excavator, concrete machine, paper machine, plastic and rubber machine, weave machine, steel plant, electronic power plant, wind power generator, other construction and industry machines or equipment. 1.we can supply various size slewing ring bearings. 2.type: non-teeth, internal teeth , external teeth 4.Diameter range:500mm-----6000mm, weight range::75.8kg--------4000kg 5.Design and manufacture according to customer needs, oem bearing. 6.High quality bearing, competitive price, prompt delivery and best services. 7.Welcome to other customized bearings , miniature bearings , auto bearings , excavator and crane bearings and so on.

Four point contact ball slewing bearing

Single-row four point contact slewing bearing (01 series) 1.Description: The single-row four point contact ball slewing bearing is composed of 2 seat-rings. The balls contact with the circular race at four point,via which the axial force, radial force and resultant moment may be born simultaneously. 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 kraft 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: Compact in structure and light in weight. 4. Application: slewing conveyers, welding arm and positioner, medium duty cranes, excavators and other engineering machines. 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;

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.

We can offer single-row ball slewing ring, dual-row ball slewing ring, single-row cross-roller slewing ring and tri-row roller slewing ring. And each kind of slewing ring has three types, non-gear, outer gear and inner gear. From small size(d=80mm) to large size(d=4000mm) slewing rings that we could make in our factory., standard or non-standard as per customers special requirement.
