Powder Metal Gears

Powder metal gears impress with their high strength and ability to form complex geometries. They are the cost-optimized alternative to mechanically manufactured parts and are used in reduction gears, decoupling gears, mass balancer gears, camshafts, crankshafts, planetary gears and ring gears. They are function-critical components in many industries, such as: cars, trucks, motorcycles, off-highway vehicles, robotics and industrial applications. The gear teeth can be in straight, helical or bevel configuration - depending on customer requirements and application.

Millions of powder metal gears in motion

Miba’s approach to the development of powder metal gears is based on our understanding of the overall system of the end application. It is our clear goal to provide our customers with the best possible support in every development phase with the latest technology. If required, we can also manufacture prototypes for our customers at short notice. As a leading provider in the field of powder metal technology, we have decades of experience in the design, validation and stable mass production of powder metal gears for a wide range of industries on three continents.

Highest competitiveness through patented densification

When it comes to powder metal planetary gear sets and components for e-drives, high performance powder metal gears combine the highest strength and precision with the advantage of improved damping behavior. This unique combination of properties is achieved by using custom alloys, which are then processed using various densification methods. Miba uses its established expertise as well as patented processes such as Densgrad® and Denscal® in surface densification processes designed for outer and inner splines.


Powder metal gears provide the right balance between porosity and high strength material.

Thanks to surface densification processes, we can virtually achieve the strength of solid steel on the surface of our components. This makes our powder metal gears as resistant as forged or machined gears. At the same time, the weight is lower than that of a steel gear. The porosity of the parts is also an advantage for NVH, as it absorbs vibrations.



The Miba PAD Decoupled Gear consists of an outer gear ring and an inner hub ring, which are decoupled by elastomer elements. In this way, the NVH of the entire gear system can be optimized by designing the required damping characteristics.
