Extensive application and design engineering experience allows EP to consistently provide reliable and cost-effective gear drive solutions for customers globally.

EP offers a wide range of products and services including single, double and triple worm and helical worm reducers, custom-engineered worm gear reducers, standard and special worm gear sets, reverse-engineered gear sets and gearboxes and gearbox rebuilding services.



Double reduction worm gearbox is a practical product developed by our company. This reducer adopts high-quality aluminum alloy casting, light weight, no rust; large torque output, large speed ratio; stable transmission, low noise; high heat dissipation efficiency.1. Efficient and safe operating
2. Compact structure and small volume saves mounting space
3. High load capacity and overload functions give stable transmission with reduced vibration.

NMRV75 worm gearbox
NMRV series worm-gear reductors are important transmission machineries. They are fit for various mounting positions and with the features of light-weight, compactibility and flexibility, they fulfill the demands of customers very well. As the advanced solutions, they are widely used in many fields: food staff, chemical and industrial industry, textile industry, electronic equipments, conveyors equipments, cranes, metallurgy, printing and dying etc.

Worm gearboxes are having cast iron gear case, worm shaft is of Alloy Steel, duly hardened and tempered. The worm wheel is made of Chill Cast Phosphorous Bronze. EP worm gear boxes have liberal ribbing for increasing heat dissipation area, streamlined sump for carrying more oil and fan of ample size which is effective in both side of rotation. Design Standards: Wherever applicable, British as well as Indian Design standards are used. Worm Shafts conform to case- hardening Alloy Steels, Worm Wheels conform to phosphorous-bronze as per BS 1400, While Gear case conforms to C.I. Grade 20, IS210.

The company has a high-tech R & D center. It is one of the professional research institutions integrating worm and worm standards, information, research, development, design, technical and experimental research, and gear failure analysis . In recent years, the company has obtained more than 100 national patents

General Purpose Cast Iron Worm Gearboxes

EP cast iron worm gearboxes (worm gear speed reducers) are mechanical power transmission components that can drive a load at a reduced fixed ratio of the motor speed. Output torque is increased by that same ratio, while horsepower is unchanged (less efficiency losses).
