Slewing Bearings With External Gear

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.

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.

As a professional triple row cylindrical roller combined slewing bearing manufacturer in China, we mainly provide internal gear type triple row cylindrical roller combined slewing bearings, external gear type triple row cylindrical roller combined slewing bearings and no gear type triple row cylindrical roller combined slewing bearings. Characteristics of Triple Row Cylindrical Roller Combined Slewing Bearing 1. Our triple row cylindrical roller combined slewing bearing has super high carrying capacity. 2. It consists of three bearing rings. The adjusting spacer between upper bearing ring and lower bearing ring can adjust the axial internal clearance. 3. Upper row rollers and lower row rollers are distributed horizontally, so as to support the axial forces and tilting moments from two directions. While radial force is supported by the third row rollers that are vertically distributed. 4. Since our triple row cylindrical roller combined slewing bearing is firm in structure and large in axial dimension and radial dimension, it is quite suitable for use in heavy duty machinery, such as bucket-wheel excavators, wheel cranes, ship cranes, port cranes, molten steel operating platforms, and so on. I am pleased to recommend our company and its bearings. Our company was set up in 1998, specialized in the design and production of slewing bearings.
