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.
