Premature failure is a common fate for large-diameter bearings in heavy-duty applications where rotations are frequent. In big rotating equipment such as cranes, excavators and tunnel boring machines, a slewing ring bearing must simultaneously handle a complex load spectrum that covers diverse combinations of thrust, radial and tilting moment loading.
The life time of slewing ring bearing is affected by many factors, including but not limited to structure design, manufacturing process, material, load conditions, speed, working environment and maintenance.
Fortunately, there’s an easy way to protect your investment in these custom engineered bearings. It’s called regular maintenance, and it can prevent 96% of slewing ring bearing failures. To maximize bearing life, simply follow these tips — raceway and gear lubrication, torque checks on bolts, and seal inspection — and be alert for four warning signs of potential bearing problems.
The material used for slewing ring bearing are normally 50Mn, 42CrMo and C45. The material will be selected according to its application and load conditions. Wanda can also try to provide the material as per customer’s requirement.
