SE7 Horizontal Small Slew Drive Bearing For Solar Tracking System
With Hourgalss Worm
Small Slew Drive Bearing Description
In the industry of slewing drives, there are many models of slewing
drives with different series. For cranes, the SE series is a
frequently used category. This series of slewing drives is
generally an enclosed design with lip seals, slewing ring
assemblies, 360-degree rotation, and self-locking gear sets. Select
models feature a dual worm gear design for increased torque
capability. Furthermore, the device can also meet the application
requirements in a high humidity environment, so that it is not
easily affected by wet weather or even heavy rain.
