Medical devices impose stringent requirements on bearing reliability, quietness, and sterility. Crossed roller bearings provide precise enabling capabilities in scenarios such as surgical robots and imaging equipment. In minimally invasive surgical robots, the low friction and high positioning accuracy of crossed roller bearings ensure the precise maneuvering of surgical instruments within confined spaces, controlling errors to the micron level, which is directly related to surgical safety and patient recovery outcomes.

In imaging equipment such as CT and MRI scanners, crossed roller bearings are used in rotating gantries and scanning systems. They must withstand high-speed rotation and complex loads while controlling operating noise below 55 decibels to avoid interfering with image acquisition and patient experience. Through raceway surface micro-texture technology and PEEK cage design, a stable oil film can be formed, reducing the friction coefficient to below 0.0015 and ensuring continuous operation for 10,000 hours without performance degradation. Addressing the strong magnetic field environment of MRI equipment, customized crossed roller bearings made of non-metallic materials are available to avoid magnetic interference, making them suitable for special scenarios such as non-invasive treatment robots.
