Hourglass Worm Gear Slew Drive For 120mm Square Tube Single Axis
Tracking System
Hourglass Worm Gear Slew Drive Description
VE7 single-axis slewing drives rotate around one axis. The VE7
slewing drive with 24vdc gear motor can be designed for different
size to fit for all kinds of main tubes. It is also a standard
product, the easiest to install, and the most commonly used. The
VE7 slewing drive offers vertical mounting and a fully-enclosed
drive in one high-powered unit.

Advantages
1. High backholding torque
2. Self-locking to improve the solar tracking system's safety
2. Hard stop inside, range from ＋60°~－60°, if customers have an
application required 360° rotaion, we have flange output type to
supply
3. Enveloping worm drive inside
4. Multi tooth contact to ensure high load and minimize backlash
Customized Services
1. Special design based on different applications and projects
2. Different types of motors could be matched, such as hydraulic
motors, stepper motors, electrical motors etc.
3. Different colors are available based on RAL code; our standard
color is RAL 9006.
Applicatons
Slewing drive bearings are usually found in application such as:
wind turbines, heavy load transporters, solar trackers, harbor
cranes, hydraulic equipment, crane steering mechanisms, automation
systems, heavy load manipulators, yaw and pitch control tables.
Q&A
1. How can i choose?
Please specify the wheel diameter size, width, voltage, power and
no-load speed of the required motors.
2. Could I take samples to test quality and market in advance?
Sure, welcome to take samples to test our quality and service.
3. What's the total cost for samples?
Total sample cost= sample cost + freight
We will give you the best shipping cost after you choose the
suitable gear motors
4. How do you ship samples?
Considering sample quantity is not big, we support ship samples by
EMS, TNT or Fedex
5. What's your minimum order quantity?
10 sets after samples confirmed
6. What's your delivery time?
For standard samples: within 7 days; for batch orders: within 25
days.
