SKF 22222 Bearing
Mobile Tower Crane Slewing Ring
Using a tower crane slewing ring as rotor,A bearing serves as a connection between two adjacent structures, allowing rotation and transmission of load between them. In addition to satisfying my requirement, a turntable bearing typically includes features for simple and quick attachment to those adjacent structures, and commonly a feature to facilitate the mechanical rotation of one ring and its adjoining structure relative to the other.
The bearing consists of an inner and outer ring made of medium carbon steel. Each includes at least one precision raceway arranged to transfer loads and relative motion from one structure of the equipment to the other.
The majority of turntable bearing applications require the bearing to transmit static load or high loads at slow rotation with operation being intermittent. If a bearing with an integral gear has been selected, the machine designer should work with a pinion manufacturer to select the appropriate mating pinion. It is important to be aware and consider all potential operating circumstances which could be detrimental to pinion and gear life.
