SKF C3996M — CARB toroidal roller bearing (C xxxx)
SKF · Bearings & Power Transmission · CARB Toroidal Roller Bearings
SKF C3996M 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. Designation follows the SKF alphanumeric identification convention where the numeric block encodes the boundary plan and the suffix declares execution options.
