Answer :

  • The vaues of radial and thrust factors X and Y are taken from the Sdt catelogue which are (X= 0.56 and Y = 1.4)
  • Bearing no. 6407 (C 55300 N )
  • Dynamic Load C = 55 300 ...........( 52615 N obtained value from calculations replaced with next value from std table C = 55300 N)
  • Shaft diameter (d) = 35 mm
