Bearing Selection14 Equivalent Load "P"As previously stated radial and axial loads must be considered separately for split roller bearings. For the calculation of theoretical life only radial loads are = Radial LoadsThe value of Fr is that calculated from standard mechanical formulae, the impact of additional forces resulting from external influences must also be = FactorUnder the influence of the above conditionsP = Fr x FzThe required theoretical Bearing life is based upon a number of factors, including reliability, accessibility and service considerations. Generally life values should be as follows:Dynamic LoadingSelection of SRB split roller bearings must take into account the effects of both radial and axial loads.
