Journal bearings used with modern turbine rotors are manufactured in two halves in order to _______________.
AI Explanation
The correct answer is D) permit removal of the bearing without removing the rotor from the turbine.
Journal bearings used with modern turbine rotors are manufactured in two halves to allow for easy removal and replacement of the bearing without having to disassemble the entire turbine. This design feature makes maintenance and inspection of the turbine much simpler, as the rotor does not need to be removed from the turbine in order to access the bearings. The other answer choices do not directly address this key benefit of the two-piece bearing design.
