NTN CORPORATION developed a cylindrical roller bearing for high-speed, heavy-duty cutting as part of its new-generation ULTAGE bearing series. It achieves a service life at least 25 times that of conventional products in grease-lubricated environments and is expected to contribute to productivity and energy savings.
NTN CORPORATION developed a cylindrical roller bearing for high-speed, heavy-duty cutting as a new product in its new-generation ULTAGE bearing series. The main-spindle bearing achieves a service life at least 25 times that of conventional products in a grease-lubricated environment, while combining high rigidity with industry-leading high-speed rotation performance.
The new product is designed for use in grease-lubricated environments and is expected to reduce maintenance requirements and improve equipment utilization. The background information explains that the shift to grease lubrication also contributes to energy savings in machine tools and the promotion of carbon neutrality.
The stated background is that faster machining and heavy-duty cutting are increasingly required, while the spread of multitasking machines means that main-spindle bearings must combine high-speed rotation with high rigidity. NTN CORPORATION pursued the development to address this challenge.
The attached release also provides related materials, reference images and the press-release text, and further information is expected to be disclosed.
