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.
