Thermax Limited Operations Engineer Interview Questions, Process, and Tips for Experienced

Bearing failure can be caused by factors such as improper lubrication, contamination, overloading, misalignment, and poor installation.

• Improper lubrication can lead to increased friction and wear on the bearing surfaces.

• Contamination from dirt, debris, or moisture can cause abrasion and corrosion, leading to premature failure.

• Overloading the bearing beyond its capacity can cause excessive stress and fatigue.

• Misalignmen...read more

The gearbox is a mechanical device that transmits power from the engine to the wheels of a vehicle, allowing for different speeds and torque ratios.
