The term total float clearance refers to what?

• A. The total clearance of all bearings
• B. The clearance taken with the thrust bearing shoes removed
• C. The gap between rotor and stator
• D. The maximum allowable axial movement

Answer: (B)

Total float clearance refers specifically to the clearance measured when the thrust bearing shoes are removed. This measurement is significant in machinery, particularly in rotating equipment, as it helps to determine the operational parameters of components such as turbines and pumps. In practical terms, total float clearance helps ensure that any axial (back-and-forth) movement of the rotor within the stator does not exceed safe operational limits. By removing the thrust bearing shoes during measurement, it allows for assessment of the maximum clearance without the influence of those bearings, leading to a clearer understanding of how the assembly will perform under normal operating conditions. This approach to measuring total float clearance is crucial for optimal machinery operation, as it directly impacts the balance and performance of rotating equipment, ensuring proper function and longevity.
