| Feature | Technical Advantage | Direct Benefit to You |
| High Ratio, Compact Design | Achieves reduction ratios from 5:1 up to 100:1 in a single stage. | Delivers massive torque multiplication while saving crucial space on your production floor. |
| Inherent Self-Locking | Due to the sliding contact angle, the worm wheel cannot drive the worm back (in most ratios). | Enhanced Safety for vertical loads (lifts, hoists) by preventing back-driving when the motor is stopped. |
| Quiet & Smooth Operation | The continuous sliding meshing of the worm and wheel minimizes vibration. | Ideal for noise-sensitive environments like food processing, packaging, and clean rooms. |
| Durable Material Pairing | Worm shafts made of case-hardened alloy steel paired with bronze/brass worm wheels. | Extends operational lifespan and maintains high performance under continuous heavy load. |
| 90o> Angle Configuration | Allows for efficient and flexible power transmission between non-intersecting, perpendicular shafts. | Simplifies machine design and integration into tight or complex assemblies. |
A Kavitsu Worm Gearbox excels in sectors where high output torque and consistent load holding are paramount.
We don't just supply gearboxes; we engineer solutions. Our Worm gearboxes are available in both standard and specialized configurations to meet the demanding requirements of your industry.
Core Specifications (Example Ranges - Adapt to your actual product specs) :
If your application demands extreme torque, a tight-space fit, and an essential self-locking safety feature, a Kavitsu Worm Gearbox is the answer.
Standard sizes and catalog models of our worm gearboxes are typically ready for immediate dispatch or have a short lead time of 2 to 3 days. For heavy-duty industrial configurations or highly customized shaft dimensions, lead times depend entirely on the design specifications and manufacturing requirements.
We offer comprehensive technical customization to match your specific machinery demands, including:
Our standard single-stage worm gearboxes support standard speed reduction ratios ranging from 5:1 up to 70:1. For complex high-torque applications requiring deeper reduction, we manufacture multi-stage or double-reduction paired gear assemblies that can achieve ratios much higher than 4000:1.
Yes, our industrial gearboxes are engineered for continuous duty cycles. Because worm gear units generate inherent heat due to sliding friction, we ensure our units feature high-efficiency heat-dissipating cooling fins, heavy-duty synthetic lubrication compatibility, and rugged cast-iron casings to maintain performance under steady load profiles.
To select the ideal model, you need to determine your required output torque, input motor horsepower (HP) or kilowatts (kW), desired reduction ratio, overhung load capacity, and mounting configuration. Our technical engineering team is available to run full load calculations and assist you in selecting the correct frame size.
