The large slewing bearing structure is mainly composed of three rows of crossed rollers. The equipment used for the extra-large slewing bearing is obviously high-value, high-performance, high-stability, high-reliability, and high-safety.
The main features of slewing bearings are low-speed, heavy-duty and high-speed precision, such as bucket wheel bearings, stacker-reclaimer bearings, shield machine bearings, ladle bearings, filling machine bearings, and radar bearings.
The process of slewing bearings is very strict and complete. The core process and technical indicators are clearly decomposed in the drawings, and some specific working condition designs and requirements must be adopted.
