Powder metal parts

Miba powder metal components are used in a wide range of industries. Whether in robotics, conveyor technology, compressors and eBikes, in medical technology or in the automotive sector - the high precision and high strength of these components means they deliver impressive cost efficiency and reduced weight. Their implementation reduces the CO2 footprint.

Powder metal technology uses several processes to produce high-strength and high-precision parts. First the Miba mixed powder metal material is pressed with in-house built precision tools to form a compact (also called a green compact), which has sufficient strength to be safely handled to the next process step. Then in the next process step the compact is sintered at a temperature of up to 1250°C. During the heat treatment, the individual powder particles combine and the powder metal component acquires its strength.

To achieve the highest possible precision and density, for some applications the component is sized after sintering and - if necessary - heat-treated, surface-coated, mechanically reworked or assembled.

Hydrodynamic bearing technology

Miba is one of the world's leading manufacturers of hydrodynamic bearings for engines, turbines and compressors. A hydrodynamic bearing also offers advantages in the gearboxes of wind turbines and aircraft turbines.

Miba hydrodynamic bearing technology delivers solutions that push other technologies to their limits

Miba hydrodynamic bearings allow a wide range of applications: At moderate speeds, dynamic loads of up to 140 MPa are possible; at low loads, speeds of up to 160 m/s.
 
Thanks to our extensive expertise in applied engineering and materials, we can offer custom-built and cost-effective solutions where other bearing technologies reach their limits. Our bearings use a hydrodynamic film to contact the shafts. Depending on the application, the use of a hydrdynamic bearing can bring advantages over roller bearings.

Versatile range of applications for hydrodynamic bearings

We have acquired in-depth knowledge over decades on the tribology of hydrodynamic bearings and bearing-mounted drive components. The breadth of our application experience (both in terms of high loads as well as high speeds) is reflected by the range of industries in which we are active with our technology.

From development and choosing materials, to testing and simulation tools as well as excellent application technology, we support our customers in finding the best solution for their application.

• Engine bearings
• Industrial Bearings
• Plain Bearings vs. Roller Bearings

Engine bearings

Markets are changing more rapidly than ever, and environmental requirements and performance demands are evolving constantly. Around the world, manufacturers of high-performance diesel and gas engines face a variety of challenges.
Thanks to its international presence, the Engine Bearing Branch within Miba Bearing Group – as a specialist for engine bearing applications and production – offers its customers flexible and customized solutions. From development to choice of materials and exceptional application engineering, right through to logistics, we stand for innovative problem-solving skills when it comes to engine bearings.

Engine bearings are crucial components playing a significant role in engine function and service life. They help position crank- and camshafts, minimize friction during operation and protect the engine from damage and breakdown. By constantly developing new types of bearings, Miba ensures that modern engines are able to deliver maximum performance efficiently and in an environmentally friendly manner even under extreme conditions.

Over several decades, we have acquired in-depth knowledge of the tribology of engine bearings and the power train components that run on bearings. Thanks to our extensive experience in many areas, we are able to offer the right solution for every bearing application. Our strengths include independence from raw materials, highly advanced, reliable production processes and efficient quality management that is focused on meeting all functional requirements as cost-effectively as possible.

Industrial Bearings

The Industrial Bearing Branch produces hydrodynamic bearings and labyrinth seals for use in critical rotating equipment, such as turbines, compressors, generators, motors, and industrial pumps. Our fluid film bearings are used in power generation as well as in the oil and gas industry and the petrochemical industry.

Plain bearing vs. roller bearing

Plain bearing vs. roller bearing: How plain bearings are successfully replacing roller bearings

In many applications, the question plain bearing vs. roller bearing goes in favor of plain bearings, due to their increase in performance. Our expertise, as one of the world's leading manufacturers of hydrodynamic plain bearings, enables us to use Miba plain bearing technology to your advantage, including in wind power and aviation.

Miba Coatings

High Tech Coatings (HTC) and Miba Precision Components (China) (MPCC) together form Miba's competence centre for coatings. Among other things, we specialize in functional coatings for NVH optimization (Noise, Vibration, Harshness), for improving tribological properties and corrosion resistance, and for increasing friction in fasteners.

As an active development partner for our customers, progress and innovation are our core value. We see complex tasks as a challenge. Our customers benefit from our customized, innovative solutions and our broad product portfolio in the field of surface coatings.

Why coating?

Coating is the process of applying a strong adhering layer to the surface of a workpiece to improve its technical or optical properties.

The coating of workpieces offers a wide range of possibilities for combining the best properties of different materials to create higher-performance products. The variety of combinations but also the adaptability to diverse applications opens up an incredibly wide range of possibilities. Whether it is a matter of classic wear and corrosion protection, electrical conductivity or insulation, friction increase and reduction, optical excellence or the possibility of easier assembly of components, the use of coatings has become indispensable. Not only the application possibilities of coatings, but also the technologies with which they are applied are numerous. Therefore, we also have various technologies at our disposal, which enable us to respond to your individual wishes. We offer various polymer, electroplating, APS and PVD coatings but also the necessary flexibility to equip your product for the desired application.

Coating solutions for increasing the coefficient of friction

With our special coating process, we increase the coefficient of friction of your component surfaces - and thus the performance of your products. Through innovative coating solutions components are for the first time provided directly, partially with a friction value-increasing coating. This saves additional components, increases performance and reduces overall costs.

Gripcoat® Direct – Friction Increase
Coating solutions to prevent friction, wear and corrosion

Our products for reducing friction and wear characteristics are used in a wide range of applications. Depending on the application and individual requirement profile, we offer you a coating solution tailored to your component. The coatings are applied to components, which, depending on the application, leads to better performance, weight savings or even the saving of entire components. Often, this is also accompanied by an anti-corrosion effect, or it is the main requirement.
