Triple Row Slewing Bearing

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;

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.

Slewing bearings are widely used in construction machinery, such as tower cranes, excavators, mobile cranes, truck-mounted concrete pumps, etc. Rothe erde slewing bearing products accompany such machines all over the world, the important things is that with the rapid development of India economy, which lead to a strong demand of various kinds of construction machinery. Rothe erde slewing bearings can totally meet the need. Any questions about your this kind of slewing bearing, please contact us, we'd like to discuss it with you.
