[PDF] SIMULATION BASED DESIGN OF A HIGH-SPEED TAPERED ROLLER BEARING …

INTRODUCTION Tapered roller bearings (TRB) show a far higher stiffness and load rating than high-speed angular contact ball bearings, so called spindle bearings (SPB). Thus, TRBs can be a favorable alternative to SPBs in main spindles for appliions with low to medium spindle speeds at high spindle loads as they occur in high performance cutting (HPC) or heavy …
