Super Precision N series High-speed Cylindrical Roller Bearings for Robot Reducers N9,N15,N17,N25,N35,N45 Robotics
Cylindrical roller bearings without an outer ring are known as outer ring-less roller bearings. Such bearings are adopted in specific application scenarios, for instance, in systems where space is limited or special configurations are required. The design without an outer ring makes the installation of the bearing more flexible, allowing it to come into direct contact with other parts to achieve specific mechanical functions. In certain industrial applications, such as automotive transmission systems or precision machinery, outer ring-less roller bearings are widely used due to advantages like compact structure, lightweight, and high load-bearing capacity.
