The Worm Reducer is a replacement for the Elecon Double Reduction Worm Gear Unit SFOD 7/170. It is designed to meet the requirements of slow-speed machinery, with a minimum transmission ratio of 75:1 and a maximum ratio of 4900:1. It can be used in under-driven, over-driven, and vertical assembly conditions. Our company offers high-quality replacement worm reducers under the Elecon brand, at competitive prices. Please note that our products are replacement parts and not original equipment. For original equipment, please contact the original supplier.

The Worm Gear Unit consists of two single reduction worm gear units. The main worm unit is specially designed to be installed as a whole on the standard single worm unit that forms the second stage. The entire gear device has a compact and sturdy structure, suitable for slow-speed machinery. The transmission ratio ranges from 75:1 to 4900:1, making it ideal for high torque, slow speed applications. The worm gear transmission meets the BS-721 standard.


The Worm Gear Unit can be applied in various industries and specific applications. It is commonly used in material handling equipment for transporting goods, packaging machinery for efficient packaging processes, conveyor systems for smooth movement of goods, textile machinery for precise fabric production, food processing equipment for hygienic food preparation, and many other applications.
