Six Row Cylindrical Roller Turntable With Teeth On The Outer Rings

The six-row cylindrical roller slew bearing with teeth on the outer ring is a key component tailor-made for ultra-heavy machinery. It is commonly used in port cranes, large mining excavators, ultra-large tonnage crawler cranes and other equipment. It consists of an inner ring, an outer ring, six rows of cylindrical rollers, a cage and a sealing device. The outer ring is processed with a high-precision ring gear, which can directly mesh with the pinion of the driving device. In the load-bearing structure, two rows of rollers are arranged along the axial direction to bear bidirectional axial loads; two rows of radial rollers are responsible for carrying radial loads; and the remaining two rows of rollers are arranged at an angle to effectively resist overturning moments. The cylindrical rollers are in line contact with the raceway. Compared with point contact, the contact area is greatly increased and the load is distributed more evenly. This allows the bearing to withstand axial force, radial force and overturning moment several times greater than ordinary slew bearings, and has extremely strong load-bearing capacity.
The outer ring gear meshes directly with the driving pinion to achieve precise power transmission, reducing energy loss during power transmission and simplifying the equipment's transmission system. Due to the large contact area between the rollers and raceways and the stable structure, it can maintain high-precision rotary motion under severe working conditions such as heavy loads and impact loads, ensuring the stability and reliability of equipment operation.Centripetal Bearings,High-Quality Bearings,Industrial Bearings,Explore our premium centripetal and radial ball bearings.
