On the occasion of the release of FYH's new version of 'Rolling Bearings with BlocksSince the company took the lead in producing rolling bearings with housing in Japan in 1950, it has gradually grown into a professional manufacturer of rolling bearings with housing that supports the development of the world's industries. In recent years, the industry has put forward higher and higher requirements for various types of machinery and devices. Correspondingly, the company has successively invested in the production of small and lightweight components (purification series), stainless steel series, ceramic series and other products. , has been well received by all parties. Among them, the ceramic ball bearing series, known as a new generation of bearings, is a product developed based on the company's unique idea of u200bu200bcombining two different materials, ceramic and metal. It can be widely used in the leading role in Japan in the 21st century. IT industry, biochemical industry, aerospace, marine development and other fields. This is partially covered in the Special Environment Ceramic Ball Bearings section of this issue. We believe that this new product will play a role in areas where traditional mounted rolling bearings cannot. We will continue to look to the ever-changing future, create new value and meet all your requirements. I sincerely look forward to your continued patronage of FYH products in the future.
