High Torque SE25 Slewing Ring With Hydraulic Gearbox, IP66 For Harbor Machine
Advantages
The slewing bearing manufacturer explained that it has the following obvious advantages:
1. Due to the high integration of the slewing drive (rotary reducer), the user does not have to purchase and process each part of the slewing drive device one by one, which also reduces the preparation process at the beginning of product production to a certain extent. Significantly increase labor productivity.
2. The double enveloping worm gear worm drive has the characteristics 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.
3. Compared with the traditional gear transmission, the rotary drive (rotary reducer) can obtain a relatively large reduction ratio. Greatly reduce the host failure rate.

Applications
Harbor cranes are an indispensable tool when transporting goods, commodities and components in ports. These cranes are usually linked by rails and feature proven technology and a long service life. Since slewing ring bearings also meet the highest demands and withstand loads, they have been used in transfer and shipyard cranes worldwide for decades. Port companies demand maximum reliability over the life of their cranes.
Port machinery requires large and robust slewing rings: they ensure the slewing capacity of deck cranes under unfavorable marine conditions. At this time, a variety of solutions are provided according to the different use cases.
We offer a wide range of proven solution options for a variety of uses. We develop slewing bearings for this field of use in detail in cooperation with our customers, design and manufacture them according to valid classification regulations.
