Details
Super-precision single row cylindrical roller bearings feature a tapered bore design that allows for axial displacement of the shaft relative to the housing in both directions. These bearings are available in both basic and high-speed configurations. The N-design is commonly utilized for non-locating bearing applications as it can accommodate heavy radial loads and high rotational speeds.
