When RC vehicles, precision instruments, or small motors lose performance, excessive friction inside rotating parts is often the hidden problem. Hybrid ceramic bearings provide a low-friction solution by combining ceramic rolling elements with durable steel races, helping you achieve smoother rotation, higher speed, and longer service life.
Shenzhen Xinchangsheng Bearing Co., LTD. (XCCZC Bearing) has manufactured precision bearings since 2002, providing customized bearing solutions for automation, automotive, medical, and energy industries. With a 5,000 m² modern factory, monthly production capacity of 3 million bearings, and exports to more than 20 countries, XCCZC delivers reliable bearing solutions for global OEM customers.
The 688 hybrid ceramic bearing is a miniature deep groove ball bearing engineered for applications where speed, accuracy, and reduced friction matter. It uses precision chrome steel races combined with ceramic balls to reduce rotational resistance and maintain stable operation under demanding conditions.
This bearing is commonly selected for RC racing upgrades, robotics, desktop CNC equipment, and compact mechanical systems.
