It is possible to manufacture bearings incorporating ceramic balls starting from one piece.
In environments where bearings are used in high-speed rotation, such as spindles, motors, machine tools, and centrifuges, bearings incorporating low-density ceramic balls (silicon nitride) are more suitable compared to steel balls. Our company offers a variety of materials not only for the inner and outer rings but also for each component that makes up the bearing, enabling the production of optimal bearings through combinations of materials tailored to specific applications. [Features] - A variety of materials are available for each component that makes up the bearing. - Optimal bearings can be produced through combinations of materials according to the application. *For more details, please refer to the PDF document or feel free to contact us.
