With the rapid development of the national economy, lifting and excavation equipment are more widely used, the structure of the main engine is more and more compact, the carrying capacity is more and more strong, and the equipment is becoming lighter and lighter. As an important component, slewing bearing/rotary disk bearing also shows the trend of lightweight. There are customers in the use of slewing support process, the occurrence of jamming, raceway collapse, fracturing and other abnormal failure phenomena.
The reasons for the stuck phenomenon of slewing bearing are complicated, but in a word, it is nothing more than:
1. The material and manufacturing technology of the slewing bearing itself are not qualified.
2. Due to the unreasonable design of slewing bearing/rotating disc bearing, the high-strength bolt connection fails. And once the circumstance mentioned above appears, it will cause unnecessary losses and troubles to customers. We sincerely hope that customers will fully consider the three important factors of quality, technology and price when choosing slewing bearing/turntable bearing, and choose the products with the best performance-price ratio.
