What is the maximum allowable clearance permitted between the bearing, shown in the illustration and the shaft along its vertical axis? Illustration MO-0121

Correct Answer: Option C — 0.80 mm

Marine engineering standards dictate a maximum vertical clearance limit of 0.80 mm for this specific bearing illustration to maintain proper hydrodynamic oil film thickness, prevent metal-to-metal contact, and control excessive shaft displacement under dynamic operating conditions.
