An analysis of centrally pivoted tilting pad bearings in the size and speed ranges of propeller shaft application is given. Temperature distribution in the oil film and pad deformation under load are considered. The analysis is made for finite sector shaped pads and moment equilibrium at the pivot is satisfied. A set of design charts which show minimum film thickness, maximum temperature, hydrodynamic oil flow and horsepower loss as functions of unit load and speed for the range of 19 inches to 50 inches O.D. bearings is included. The effects of pad subtended angle, pad thickness, radial pivot location and groove mixing temperature on load carrying capacity are considered.
