Product Overview
Dental instruments represent one of the most demanding applications for ball bearings. Not only mechanical stress, but environmental factors also pose significant challenges:
- Extremely High Speeds: Up to 500,000 RPM
- High-Temperature Sterilization: Must withstand autoclave processing
- Chemical Corrosion: Exposure to various cleaning solutions
Optimyn Brand Advantages
Uncompromising Reliability at a Competitive Price
The Perfect Balance of Quality and Price
The Optimyn brand of dental handpiece replacement bearings eliminates the compromise between quality and price, offering a range of standardized replacement bearings covering most common dental applications.
Dental repair businesses face an ongoing challenge: meeting the performance requirements of end users (dentists) while remaining competitive in a price-sensitive market. As a result, many aftermarket customers have been reluctant to purchase high-quality bearings from market leaders like myonic and our sister company NHBB, opting instead for lower-quality solutions.
Now you no longer have to sacrifice market leadership for affordable aftermarket bearings. The Optimyn product line meets the demand for reliable solutions at a lower price point by combining component standardization with the high-volume manufacturing resources of Minebea, the world's leading vertically integrated manufacturer of miniature precision ball bearings. This is a solution that only a market leader with a global manufacturing footprint can provide.
