Recently, a batch of slewing bearing products produced by our company for a large maritime hoisting crane enterprise were delivered on schedule.

Because maritime cranes work at sea, the environment is complicated, and the safety requirements of the equipment are higher. Maritime cranes are special cranes that perform transportation operations in the maritime environment. They are mainly used for important tasks such as the transportation and transfer of cargo between ships, maritime replenishment, and the release and recovery of underwater operating equipment. The special application environment at sea brings great challenges to the control of marine cranes.In order to ensure the safety and reliability of cranes working at sea and improve work efficiency,Xuzhou XZWD slewing bearing Technology Department chose a double-row four-point contact ball slewing ring for the customer.

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.

We also provides CCS classification society certification for marine products.

It is certified by China Classification Society.
