Inner Rings

Inner Rings are prepared for needle roller bearings without an inner ring, and its outer circle is used as an inner raceway. The outer ring diameter of BSPD’s Inner Rings can be made larger, so that after pressing the Inner Rings into the shaft, users can grind the outer circle of the Inner Rings based on the shaft core to ensure the concentricity of the raceway and the central spindle.
