Ip66 Enclosed Se9 Hydraulic Slewing Ring Bearing For High Accuracy Rotatary Machines
Hydraulic Enclosed Slewing Drive
The slewing drive is a complete system assembly that can be easily installed and integrated into existing system programs.
It is composed of ball slewing bearing or cylindrical roller slewing bearing, worm, shell and other parts that can bear axial, radial and overturning moments at the same time. The worm is driven by a hydraulic motor or motor to drive the slewing bearing to rotate. The surface of the housing is spray-coated and fully enclosed with seals to protect the slewing drive from contamination, damage and grease loss.
These components are assembled together to avoid customers installing various mating components, and we can also provide a variety of size standards.

Advantages
Modularization: Due to the high integration of the slewing drive pair, users do not have to purchase and process each component of the rotating device one by one, which also reduces the preparation process at the beginning of product production to a certain extent, thereby greatly improving labor productivity.
Safety: The worm gear and worm drive (slewing drive pair) has the feature of reverse self-locking, which can realize reverse self-locking, that is, only the worm can drive the worm gear, but the worm cannot be driven by the worm gear to move. This feature makes the slewing drive widely used in lifting, aerial work and other equipment. While improving the technological content of the main engine, it also greatly improves the operation stability of the main engine and the safety factor of the operation.
Simplify the design of the main engine: Compared with the traditional gear transmission, the worm gear transmission can obtain a relatively large reduction ratio. In some cases, the reducer parts can be omitted for the main engine, thereby reducing the procurement cost for customers and greatly reducing the failure rate.
Applications
Other names of slewing drives: rotary drive device, rotary gear device, rotary reducer, rotary turntable device, worm gear drive, turbine worm pair, worm gear pair, turbine worm device, mainly used in aerospace, tower cranes, excavators , construction machinery, satellite receiving systems, solar tracking systems and many other industries. Especially in recent years, the rapid development of solar photovoltaic power generation industry is widely used.
