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.
