XZWD high quality Slewing bearing for maritime crane
The double-row four-point contact ball slewing bearing structure is similar to the single-row ball slewing bearing, except that it uses two rows of steel balls as rolling elements, the two rows of steel balls have the same size, and a single isolation block is set between the steel balls. The inner and outer rings are integral, and the steel balls are inserted by plugging the holes. It is the first choice for the main engine with heavy load and limited radial structure size.
Maritime cranes work at sea, the environment is complicated, and the safety requirements of the equipment are higher. So in order to ensure the safety and reliability of cranes working at sea and improve work efficiency,XZWD Technology Department chose a double-row four-point contact ball slewing ring for the customer.
