WORM GEAR VS SLEW DRIVE
Selecting the right gear for your application is essential for achieving optimal performance and durability. Double-enveloping worm gears are ideal for applications requiring high torque output and high shock-load resistance, while slewing gears excel in smooth, controlled rotation for handling heavy overhung loads. Understanding the distinct benefits of each can help you make the best choice for your specific needs.
WORM GEAR
SLEW DRIVE
What is worm technology?
Worm technology is based on a worm screw meshing with a gear to transmit motion and torque. The threads of the worm engage with the teeth of the gear, creating a high reduction ratio in a compact space. Worm drives are used when a high reduction ratio and shock-load capacity is required.
What are the advantages of worm gear drives?
Worm gear drives offer several advantages that make them a popular choice for various applications including:
- High reduction ratios in a single stage design, reducing the need for complex multi-stage gear trains
- Continuous or high-duty cycles for sustained loads over long periods
- Smooth and quiet operation due to the sliding contact between the worm and gear
- Compact design that can fit into tight spaces while delivering high torque output
What applications use worm gear drives?
Worm gear drives are used in various applications that require high reduction ratios and compact designs. Common applications include:
- Conveyor systems
- Elevators and lifts
- Steering mechanisms and positioning equipment
- Industrial machinery and manufacturing equipment
- Gate and valve actuators
- Solar and satellite trackers
What is slew drive technology?
Slew drive technology builds upon the principles of worm drives but integrates additional features for enhanced load bearing and rotational capabilities. Slew drives combine a worm gear mechanism with a turntable bearing, allowing them to manage high axial, radial, and moment loads while maintaining smooth motion.
What are the advantages of slew drives?
Slew drives provide additional benefits beyond those of standard worm gear drives. These advantages include:
- Ability to handle high axial, radial, and moment loads, making them ideal for heavy duty applications
- Enhanced torque transmission and load distribution due to the integration of a turntable bearing
- High durability and longevity due to their enclosed design that protects against environmental contaminants
- Simplified installation and maintenance
What applications use slew drives?
Slew drives are widely used in applications that demand high torque and the ability to handle significant overhung loads. Typical applications include:
- Solar tracking systems
- Construction equipment such as cranes and excavators
- Wind turbines
- Aerial work platforms
- Robotics and automation systems
- Satellite tracking systems
How to decide on which kind of drive to use?
Your applications requirements will dictate which option you choose.
If your application requires a compact design with a high reduction ratio, a worm gear drive may be the better choice.
If you need a drive that can handle high overhung loads while maintaining smooth rotational movement, a slew drive is likely the more suitable option. There are multiple uses for each type of drive.

Cone Drive slew and worm gear drive options
Cone Drive provides a wide range of motion control gearing options for use in a variety of industries.
Cone Drive double-enveloping worm gearing options provide high torque capabilities in small packages, available in servo and NEMA driven options.
Our slewing solutions offer low profile turning power, providing smooth rotation and shock resistance.
WORM GEAR SOLUTIONS
Cone Drive’s double-enveloping worm gear technology is unsurpassed where both precision and accuracy are required. We manufacture quality, durable worm gearsets in standard sizes and ratios or we will meet custom specifications. The greater surface area contact of double enveloping worm gearing means the load is distributed across more teeth which allows the worm gear to run cooler, quieter, and more efficiently. Cone Drive’s worm gear design helps provide cost savings with no loss in performance.
SLEWING SOLUTIONS
Cone Drive’s rugged, durable slewing solutions provide a large ratio in a single stage. The slew bearing and gears can be assembled into a low profile, self-retaining, and ready-to-install housing optimized for weight versus performance. These highly-adaptable products feature strong shock resistance, long life performance, smooth rotation, bearing protection, and sealed drive options. We can provide custom slew bearings and drives in addition to drop in replacements that are in stock for select styles.
