Triple-row Cylindrical Roller Slewing Bearing

These Triple-Row Cylindrical Roller Slewing Bearing is a large-scale integrated load bearing, which can bear large axial load, radial load and overturning moment. Slewing ring bearings are generally of inner gear or outer gear, mounting holes, lubrication holes (oil holes), and seals, which can make the host be an compact design, easy to guide and maintain.
Triple-Row Cylindrical Roller Slewing Bearing can be no gear, internal gear and external gear. The slewing bearing types are mainly as follows:
1. Four-point contact ball slewing bearings
2. Double-row different diameter ball slewing bearings
3. Crossed cylindrical roller slewing bearings
4. cross-tapered roller slewing bearings
5. Triple-row cylindrical roller slewing bearings
Of these slewing bearings, four-point contact ball bearings are of high static load capacity,
cross-cylindrical roller bearings are of dynamic load capacity,
cross-tapered roller bearings' pre-interference can can support a greater rigidity and rotary accuracy,
three-row cylindrical roller bearings increase the carrying capacity and can bear a more heavy load, because forces are beared by different raceway. So three-row cylindrical roller bearing is a high carrying capacity of slewing bearings, because, in the same force cases, the diameter of the bearing can be greatly reduced. Hence the characteristics of the host is more compact.
In reality, slewing bearings are widely used in industry and known as "the machine joints".
