The bearing shown in the illustration is designed to carry thrust when applied __________. Illustration MO-0001

Correct Answer: Option A — right to left only

Tapered land thrust bearings are engineered with specific geometry to support axial loads in one direction. The wedge-shaped oil film created between the bearing surface and the collar allows for hydrodynamic lubrication. If the thrust load is applied in the opposite direction, the oil wedge cannot form, leading to immediate failure.
