Product Description
SKF C3972KM carb toroidal roller bearing (c xxxx). Single-row roller bearing with long, slightly crowned rollers rolling in a toroidal outer raceway — combines the self-alignment of a spherical roller bearing with the axial-displacement capability of a cylindrical roller bearing. Fitted on the non-locating shaft position of a paired shaft arrangement so shaft thermal expansion is absorbed internally.
