Three-row cylindrical cross roller slewing bearing 13 series 1. Description Three-row cylindrical cross roller slewing bearing has three seat-rings, which separate the upper, lower and radial raceway, via which the load of each row of the rollers may be specified. Thus it can carry different load simultaneously and its load capacity is the largest one of the four types 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 prevent the rust or the moist; 4 We can depend on the customers demand to be packed 3. Features larger axial and radial dimension, compact structure 4. Application Especially used in heavy-duty machines which require large working radius, such as bucket-wheel excavators, wheeled cranes, ship cranes, ladle turret, auto cranes etc. 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;

Under normal circumstances, slewing bearings have their own mounting holes, lubricants and seals, which can meet various of host need under different working conditions; on the other hand, slewing bearings themselves are compact, easy to guide the rotation, easy installation and easy maintenance, so they widely used in material handling equipments, mining machines, construction machinery, port machinery, wind power generation, medical equipments, radar and missile launchers and other large rotating devices. According to different structure, slewing bearing can be divided into the following types:1, the four-point contact ball slewing bearing2, double row different diameter ball slewing bearing3, crossed cylindrical roller slewing bearings4, three-row cylindrical roller combined slewing bearing. 011.45.1600.Dimensions:1740*1460*110

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.

This type bearing has a very high radial load capacity but no axial load capacity. With relative smaller radial measurements, it gives a higher limiting speed. Fc type has two outer rings with ribs, full set of outer ring(ourter ring, rollers and cages), and one inner ring. Cages are rib-type. Fcd type has two outer rings with ribs, full set of outer ring(ourter ring, rollers and cages), and two inner rings. Cages are rib-type. Fcdp type has two outer rings without ribs, full set of rollers and cages, two inner rings, two rib rings and one middle snap rib ring, Cages are pin-type. In the view of position of lubricating bore, they have following types Fc: the sides of outer ring have lubricating groove Fc/a1: the radial surface has lubricating groove and oil bore¡£ Fcd: the sides of outer ring have lubricating groove. Fcd/a1:the radial surface of outer ring has lubricating groove and oil bore. Fcd/a13:both the sides and radial surfaces have lubricating groove and oil bore. Fcdp:the radial surfaces of both outer ring and middle rib ring have lubricating groove and oil bore. 80x80x80cm
