For a Double groove angular contact ball bearing with dimensions as given below: Estimate the following: a. Calculate life of the bearing (in revolutions), by considering the acting radial load as 400 kg. b. The bearing was fixed to a base by using M10 shaft with a tightening torque of 14 N-m. Estimate the effect of tightening torque (axial load) on bearing life. c. Estimate what is the appropriate tightening torque for the considered bearing from the view-point of bearing life. Axial load Base d. Estimate the impact load bearing capacity of bearing, in- case the bearing assembly drops from a height of 200 mm. D D rap T2 r1 d d D D = 24 mm; d = 12 mm B = 10 mm; angle of contact - 30 degrees Dynamic load rating - 7 KN Static load rating - 3.8 KN d
