Hypoid Reducer JKM header

Hypoid Reducer JKM

The JKM series hypoid reducers feature a high-efficiency right-angle transmission and are suitable for IEC flange mounting. Within the Euronorm JKM-series motor gearboxes program, various versions are available that are interchangeable on a 1-to-1 basis with other manufacturers. These gearboxes are standardized for IEC flange motors B5 and B14a.

Product Info

The Hypoid Reducer JKM and JKB series represent a new generation of reducers designed for high efficiency, contributing to cost reduction through energy-efficient motor gearboxes. The design takes into account the interchangeability with existing traditional worm gear reducers.

Options for the JKM series hypoid reducers include:

  • Interchangeability with traditional worm gear reducers.
  • Energy savings compared to traditional worm gear reducers (efficiency ranging from 92% to 94%).
  • High transmission capability.
  • Reduced environmental impact.
  • Two- and three-stage versions
  • Rated power from 0.12 to 4.00 kW
  • Gear ratio from 1:7.5 to 1:300
  • Input speed of 1400 rpm
  • Output torque from 100 to 500 Nm
  • Shaft sizes from 20 to 40 mm
  • Equipped with a flange or a solid input shaft

These reducers are developed with a focus on maximizing efficiency, ensuring seamless compatibility with conventional counterparts, and promoting energy savings. With efficiency levels ranging between 92% and 94%, they outperform traditional worm gear reducers, providing not only cost-effective solutions but also contributing to environmental sustainability. The design prioritizes a large transmission capacity, ensuring robust performance across various applications while minimizing the ecological footprint.


Gearbox size:28 ~ 58
Ratio:7,5 ~ 300
Output torque:10 ~ 500 Nm
Power:0,12 ~ 2,2 kW
Output shaft size:20 ~ 40 Ø mm


Product description

Hypoid Reducer Type JKM

The Hypoid Reducer JKM and JKB series represent a new generation of drive products. A new compromise has been found between price, efficiency, and compactness.

The key features are:

  • The hypoid stage offers a large gear ratio, significantly larger than a bevel gear stage, with almost the same efficiency. The hypoid stage has a lower gear ratio than a worm gear stage but significantly better static and dynamic efficiency.
  • High “torque density”; a lot of torque from a small drive and efficient. Additionally, it has low environmental impact and energy costs.
  • Made of high-quality aluminum alloy: Lightweight and corrosion-resistant.
  • Rotates very smoothly and quietly. Excellent “back drive” performance (hardly any braking effect).
  • Suitable for various applications and easy to install.
  • The installation dimensions of the JKM series are interchangeable with, among others, the JRSTD and NMRV series worm gear reducers. The installation dimensions of the JKB series are interchangeable with, among others, W-type worm gear reducers.
  • With the modular design, many different combinations and installation methods are possible. This allows this type of drive to be used in various applications.
Quality – Stock

Hypoid Reducer


The quality of the drive is guaranteed by producing exclusively under UNI EN ISO 9001:2008 standards. Supplied materials are also rigorously inspected and chosen for their proven quality.

The use of A-brand wear parts such as NSK bearings and Simrit oil seals, finely machined components, and the application of precisely hardened and ground gears (grade 6) ensure a long lifespan, minimal noise, and high efficiency.


Euronorm keeps a large inventory of worm gear transmissions in stock and can deliver them quickly. Additionally, there is ample availability of various motors and other drive components.

Euronorm is also capable of making modifications in its own workshop, assembling drives, and painting them in the color of the customer’s choice.All of this is accomplished within a limited timeframe and from existing stock.
