Dental bearings
Ultra precision made by myonic
A dental bearing must withstand the most extreme conditions and is also one of the most crucial components for the performance of a dental instrument.
Our application expertise
Speeds of up to 500,000 rpm, vibrations, superheated steam, various cleaning media, and penetrating contamination such as blood and dental dust. These are the major challenges for these special ball bearings.
We meet these challenges with custom designs and a targeted selection of materials and lubricants.
The result is a product that is tailor-made for the application and meets all requirements over a long period of time. Challenge us! Our developers look forward to solving new and tricky problems every day!

Development
Custom requirements
Every dental application has its own challenges. myonic specialises in providing solutions for all customer-specific environments.
Market demand
The dental industry is mainly driven by three aspects:
While most OEMs aim for the longest possible product life in order to secure their market position and reputation, there are regions in the world where customers still require a quality product, but the price is absolutely paramount. In the spare parts market, the availability of quality products is the most important factor. None of the above requirements is more important than any other.

Dental bearings
Covering the needs of the entire dental market with a flexible product portfolio
Our customers not only have different applications, but also different needs in terms of volume, lead time and pricing. Dental handpiece manufacturers need customized solutions for new products.
Aftermarket suppliers need a wide variety of established geometries at competitive prices. Both groups have different expectations; therefore, we develop our products to meet the specific needs of customers and their dental applications. We are a proven leader in the market for bearings used in dental instruments. In-depth know-how in the development and production of bearings for OEM applications worldwide, combined with the standardization of components, results in a cost-effective bearing for all common dental applications.
We distinguish between 3 product categories for dental bearings:
Customer-specific solutions
Developed solutions for the next generation of dental tools
Our customized solutions range from the simple integration of new products into existing designs to multi-year projects in which completely new bearing concepts are developed, manufactured and validated.
Customised cover configurations
Unique cage geometries to optimise bearing dynamics

optimyn™ Line
The perfect balance between cost, customization and availability
The optimyn bearing range combines unparalleled customization options with defined standards. If a standard design can be incorporated into a new market or product, the optimyn line is the most efficient way to do it. Some of the most common variations in geometry, material selection and packaging can be customized in the configuration while maintaining an attractive price.

Elemental Line
Standardized products that meet the needs of the low-speed market at competitive prices and quantities
With the Elemental line, simplified product selection eliminates the need to worry about configuring every aspect of the bearing design. MinebeaMitsumi brings together all the expertise within the group to produce high-quality dental bearings with the cost benefits of highly efficient, standardized large-scale production.
EL Linie designation system
A typical reference would be “EL 740 Z”, which would be an elemental bearing with a covered side, steel balls, steel cage, P25 radial clearance and oil.
Special materials for special products
Developing the basis for a precision product
Special requirements apply to the materials used in a dental instrument.
For the production of our bearings, we use the most widely used rolling bearing steels. However, we purchase them with our own specifications in order to achieve a fine-grained structure and maximum hardness. In addition, the MinebeaMitsumi Group has developed nitrogen-alloyed steels that can be used to achieve even higher corrosion resistance.
We use only the highest-precision industrially manufactured balls available on the market. You have the choice between balls made of 440C corrosion-resistant steel or ceramic.
myonic offers a variety of cage materials suitable for a wide range of markets. The standard material is phenolic resin, which has proven itself on the market for many years and is widely used.

has established itself as a high-performance material with a good mix of emergency running properties and autoclave resistance.
is our highest-quality cage material. Our exclusive PI formulation outperforms all other known cage materials on the market.
In addition to the well-known and proven greases used in dental technology, myonic has successfully developed and uses its own high-speed dental greases. If required, even lubricants with H1 approval are available.
Some of the above materials are only available from the MinebeaMitsumi Group due to exclusivity agreements with material suppliers. With ongoing development programmes, we ensure the continuous further development of our products and processes.
Dental spindles
The function of the spindle (Also known as the collet chuck) is to hold the tool, drill or milling cutter securely during operation and to guide it precisely.
Major challenges include tens of thousands of opening operations, corrosion caused by water or aggressive media and high speed.
The durability of this component is the most important factor for patient safety.
Turbine units
The myonic collet offers the unique possibility of perfectly pairing the high-speed bearings established over decades with the adjacent component.
In combination with the rotor, which is also manufactured in-house by myonic, the result is an ideally matched turbine unit that can be installed in the instrument without any further adjustments.
Accessories
The extreme conditions myonic bearings have to withstand in operation require the most ideal environment possible.
Despite a precisely manufactured instrument housing, it is necessary to protect the bearings from being overloaded or having excessive clearance. For this purpose, myonic offers the appropriate accessories such as shims and spring washers, snap rings and bushings for ideal assembly.

Information from our customers
“Exceptional Supplier 2022” at Dentsply Sirona
The “Dentsply Sirona Global Supplier Forum 2022” – a high-caliber supplier conference – was held virtually for the second time in May. Dentsply Sirona Inc. was formed in February 2016 through the merger of DENTSPLY International (USA) and Sirona Dental Systems (DE) and has since become the world’s largest manufacturer of dental products and technology with a turnover of over 4.25 billion dollars/year and is also one of our main customers.
At the event, Dentsply Sirona’s managers gave their presentations online to more than 200 top suppliers, who were connected worldwide via their computers. In 2021, Dentsply Sirona introduced its new “Supplier Awards Program for Exceptional Partners”.
All suppliers have the opportunity to participate in this competition.
The criteria for the award program are based on Dentsply Sirona’s procurement goals: sustainability, quality, delivery performance, innovation, partnership and diversity.
Intensive collaboration has paid off
For the application, myonic worked intensively with the responsible purchaser for several months in order to submit all the required documents on time.
Out of around 12,000 suppliers, only 70 companies were nominated for the title of “Exceptional Supplier Partner”, of which only one was ultimately awarded in each of the seven product groups for “Direct Material”.
myonic was honored in the “Rest of Spend” category, which primarily includes steels and products made of metal, such as bearings.
Award for exceptional performance
In his video message, the responsible director, Todd Dunn, emphasized not only the outstanding delivery and quality performance, but also the very good development partnership between our companies. Our clear concept of becoming climate-neutral by 2030 was particularly emphasized!
It was even nicer to receive the award personally from the Dentsply Sirona team a few months later.
We would like to express our sincere thanks for the many years of successful and good cooperation!
