A new graduate working for a local company, is given the task of selecting suitable tapered roller bearings for the application shown in the figure below. He/she is to select the bearing from Timken Co. Catalog given in the textbook. He/She is also given the following information about the applicati 1. 2. The shaft is also subject to a thrust load of 10 kN as shown in the figure. 3. The shaft rotates at 600 rpm 4. The shaft is in a piece of a machine designed for short operations of 5 kh. 5. The reliability goal for the bearing set is 96%. Show all your work. 20 kN radial load Commercial Gear style 10 kN Thrust load H 150 mm -100 mm 250 mm
