When it comes to choosing a slew drive for your application, one of the most important decisions you’ll make is whether to go with a single worm or double worm configuration. Each option has its own strengths and trade-offs, and understanding these differences can help you select the best fit for your equipment’s performance, safety, and precision needs.
At Potesta & Company, our SlewPro line includes both single and double worm slew drives, available with a variety of motor options and modular configurations. Here’s how the two compare:
Single Worm Slew Drives
How It Works:
A single worm drive uses one worm gear to rotate the slewing ring, offering smooth and controlled motion.
Pros:
- Compact design: Ideal for applications with limited space
- Lower cost: Fewer components mean reduced upfront investment
- Efficient for light to moderate loads: Perfect for applications where extremely high torque isn’t needed
Cons:
- Lower torque capacity: Not suitable for very heavy or off-center loads
- Less braking redundancy: Only one worm means fewer mechanical failsafes
Best-Fit Applications:
- Solar trackers
- Small utility lifts
- Light-duty truck cranes
- Agricultural equipment
