High-precision cylindrical roller bearings Cylindrical roller bearings of this design are double-row precision bearings for machine tools. They allow radially rigid, high-precision bearing arrangements and are principally used to provide radial support for main spindles. The bearings comprise solid outer rings without ribs, solid inner rings with three ribs and cylindrical roller and cage assemblies with solid brass cages. For optimum setting of the radial internal clearance, the inner ring has a tapered bore with bore taper 1:12. The cylindrical roller bearings are separable and are therefore easier to fit and dismantle. Both bearing rings can be given a tight fit by this process.
